External gear synchronous motors are widely used in hydraulic synchronous systems due to their robustness and low cost. However, the noise of the motor is one of the limiting factors. The main source of noise comes from the pressure and flow pulsation during gears meshing. One of methods to reduce the noise is to analyze and optimize the tooth profile and meshing volume. However, the accurate measuring and modeling of the tooth profile are the preliminaries required for the accurate determination of the relationship between tooth profile and pressure pulsation. This paper reports a non-contact measurement method using optical CCD and laser displacement sensors to measure the tooth profile of an external gear synchronous motor. Tooth profile testing device is set up and the actual tooth profile model is measured. Regional numerical simulation of the internal flow field with the actual tooth profile is done using CFD (computational fluid dynamics) software. Preliminary results showed that different gear teeth profile functions could affect the pressure pulsation properties of an external gear motor, and CFD resulting using the actual gear profile is more comparable to the measurement.

An approach is proposed for improving the position precision and superior dynamic performance in a twin direct-drive motor system with a wire rope in the arc guide rail. For the position control motor, 2-DoF controller is introduced to the system, where the inner loop controller combined the Fuzzy-PID with velocity feedforward and the outer loop controller combined the disturbance observer (DOB) with PID, to improve the position precision and superior dynamic performance. For the motor providing pre-tightening force, PID controller is utilized to keep the wire ropes in a state of pre-tightening. The simulation result shows the high tracking performance and the effectiveness of the proposed algorithm.

The energy dissipation mechanism of hydraulic viscous damper was studied considering the shear thinning effect of dimethyl silicone oil. The analysis indicates that most of the energy loss occurs in the damping hole, which is mainly manifested as the damping loss along the path. The calculation formula of damping loss is simplified by assuming boundary conditions and the theoretical curve is drawn. The result shows that for the damping holes with the same size, the velocity and viscosity of oil are the key parameters to determine damping loss. But for different sizes damping structures, length- diameter ratio is the main factor affecting the energy loss, which in essence affects the pressure capacity of damping holes. Subsequently, the rationality of the above conclusions is verified by experiment, and two kinds of low-index hydraulic viscous damper were designed. The experimental results show that the algorithm can predict the mechanical properties of the damper well.

A composite electro-hydraulic heave compensation system that can work under two modes, i. e., the passive mode and the semi-active mode, based on an asymmetric servocylinder controlled by a servo-valve is investigated in this paper. Firstly, this composite heave compensation system, which is scaled according to the principle of similarity from its prototype system, is introduced about the system configuration and its working procedure. Based on the transfer function of the electro-hydraulic system and the nonlinear relationship between input voltage and output velocity of the asymmetrical cylinder, a piece-wise feedforward controller is obtained to improve the dynamic performance. The two modes of this composite heave compensation system are then built and simulated in the AMESim environment, lastly, the scaled ship have motion is reproduced, the resonace zone and the compensation efficiency is discussed. The simulation results show the effectiveness of the system.

The Autonomous Underwater Vehicle (AUV) is a submersible with energy, autonomous navigation, and a wide range of sensors, which is an important means of marine observation. More and more attention has been paid to the long-term observation of the marine environment using AUVs. Due to the restriction of energy and operation mode, traditional autonomous underwater vehicle can work very short time. In order to meet the long-term observation requirements of marine environment, a new type of autonomous underwater vehicle named Long Term Station-keeping Profile Observing AUV with variable buoyancy system has been developed. By carrying the variable buoyancy system, the AUV can be adjusted to neutral before travelling which will help to reduce the resistance; When vertical profile observing, the AUV’s diving and surfacing are realized by VBS without continuous power consumption; During the observation interval, AUV is adjusted to neutral in water, and by closing the carrying equipment, the AUV gets into sleep state so as to save energy. Through these measures, it is expected to achieve long-term observation by AUV for one month. The key is the high precision variable buoyancy system with bidirectional regulation ability, which can adjust the residual buoyancy and pitch angle at any working depth. In order to realize the precise adjustment of buoyancy, a seawater piston cylinder is adopted. By measuring the position of the piston in the sea water cylinder accurately, the precise control of the amount of buoyancy adjustment can be realized. Through laboratory proofing and sea tests, the variable buoyancy system has attained its design targets expected. The AUV equipped with this system can realize underwater suspension at fixed depth, diving, surfacing and low energy sleep, which has carried out many marine applications in the Yellow Sea, the South China Sea and the East China Sea, and it proved to be stable and reliable. The results of laboratory and sea tests show that the variable buoyancy system with seawater cylinder features high accuracy and reliable operation.

The large flow rate high speed on/off valves (LFHSV) have often been used to control flow or pressure in large power applications due to its fast switching. However, the applications of LFHSV are limited by vibration and noise. In this paper, CFD simulations of a two-stage LFHSV are conducted to analyze the flow field characteristics of the main poppet valve, including flow simulation under fixed opening and the transient flow simulation. Results showed that there are two vortexes formed in the flow channel which extract the energy from the main flow and intensify the fluid noise, and that the inlet pressure peak increases by 8.6% in the closing stage. The results will provide guidance for the optimal structural design of high speed on/off valves.

The multistage throttle orifice plate is a fluid pressure reducing device in the pipeline, its depressurization effect is affected by different parameters, such as the position and diameter of the holes in the throttle orifice plates, the distance between the throttle orifice plates. A numerical computational resource is required to achieve the flow characteristic with different parameters by computational fluid dynamics (CFD). Based on the neural network model of CFD simulation, the prediction of flow characteristic of multi-layer throttle orifice plate is realized in this paper. In the procedure, an automatic CFD simulation procedure of multilayer throttle orifice plate is constructed. Through the Latin Hypercube Designs (LHD) method, the parametric geometric model is generated. Then the flow rate of throttle orifice plate under different parameters are achieved under adaptive mesh generation technology and CFD simulation. The relationship between geometric parameters and the flow rate of throttle orifice plate is studied by multi-layer back-propagation neural network algorithm, and the flow characteristic predictive model is established. Compared with CFD simulation results, flow rate predicted by the predictive model and the maximum predictive error is 0.5%.

In order to improve the adaptive capacity of hydraulic drill rigs under complex geological conditions, a novel load-sensitive control valve based on a reducing valve with load-sensitive control module is proposed. It solves the problems existing in the propulsion of mining drills and realizes the thrust adaptive function. The fluid simulation model of the load-sensitive control valve is established. The variation of the pressure at the outlet of the reducing valve under different starting pressures and feedback spring stiffness is studied. The simulation data are compared with the experimental data. It demonstrates that the load-sensitive control valve can effectively adjust the driving force of the oil cylinder and reduce the bit wear when the load pressure is raised suddenly.

Aiming at investigating the fluid-solid-dynamic behaviors of the liquid-end of high-pressure and high-flow-rate reciprocating pump in pure water medium, the dynamic characteristics of the suction and discharge valves of liquid-end based on AMESimhydraulic system simulation technology and the flow field distribution in the liquid-end based on FLUENT CFD technology are established. Three-dimensional finite element (FE) analyses on the strength of liquid-end manifold were carried out by the use of ANSYS commercial code. The AMESim simulation results show that the maximum impact velocity of the discharge valve is 0. 347m/s and the volumetric efficiency is 99.53%. Based on the CFD results, the effect of the configuration of flat valve on the vibration and noise behavior during the suction and discharge processes of the liquid-end manifold is discussed. The FE results suggest that the maximum stress in a value of 198 MPa occurs at the intersecting holes of the liquid-end manifold. The FE-based safety factor is 3. 21, which meets the fatigue strength requirements for important parts.
