The power system of electric-drive truck equipped with hybrid energy storage is proposed to efficiently utilize the engine power and braking regenerative energy. The truck power system model including the hybrid energy storage system is built in which the energy management of mining truck is designed with the minimizing fuel consumption. The optimal output engine power under the cycle working condition of the truck can be predicted by the model predictive control method. Taking the advantage of battery and supercapacitor, the power distribution strategy of hybrid energy storage system is suggested to make the engine operating around the optimal fuel consumption curve. This energy management strategy of the truck is executed in realtime with the driver-in-loop. The results indicate that this energy management strategy can reduce the fuel consumption up to 13%~15% comparing with that of traditional electricdrive truck.

In order to eliminate the tooth surface errors and ensure precision of spiral bevel and hypoid gears generated by the duplex helical method, two new methodologies for the format gears and the generated gear or the pinion manufactured by the duplex helical method are proposed. Firstly, the cutting characteristics of this method is analyzed, both mathematical models for the format gear and the generated gear or the pinion generated by the duplex helical are established, one includes 8 machine settings, the other one includes up to 40 universal motion coefficients. Furthermore, the tooth surface errors of the grid points are represented by up to 6th order polynomials, then Constraint Least Square Method for determining the appropriate changes of the corrective machine settings is proposed to minimize the tooth flank form errors. Finally, new tooth flank form error correction software for spiral bevel and hypoid gears has been developed and a hypoid gear set generated by the duplex helical method is used as an example to validate the effectiveness of the software. The results reveal that the flexibility and efficiency of the tooth flank form error correction for both format gear and pinion generated by duplex helical method are greatly improved. In addition, the new approach can also be applied to the tooth flank form error correction of bevel and hypoid gears generated by other process methods.

The guiding mechanism is the key structure to ensure the lateral stability of the maglev vehicle. It is designed to bear large static and dynamic loads. In this paper, the finite element method is used to analyze the strength, stiffness and fatigue life of the simplified guiding mechanism. The calculation results show that the stress, deformation and fatigue life of the guiding mechanism meet the design requirements, ignoring the plastic deformation in a small range and the explainable stress concentration phenomenon near the constraints, loads and connections.

In order to predict the variability of modal parameters and dynamic responses of container cranes' trolley-boom system with both structural and load interval uncertainties. This paper solved the motion equation of the trolley-boom system using mode superposition method and Duhamel's integral, and the closed-form solution of the bounds on modal frequency, mode shape and modal coordinate, is derived according to interval analysis and the mechanical characteristics of container cranes. The method utilizes an interval formulation to quantify uncertainty presented in structural and load parameters, including span length, area moment of inertial, load amplitude and load moving speed. This new method was then utilized to analysis the interval dynamic response of two numerical examples. The results confirm that the relevant functions are taken as functions of time and/or spatial position, and therefore can reveal the variation of the bounds on dynamic properties with time and/or spatial position. Efforts are also made to evaluate how the uncertainty of load and structural parameters attribute to bounds on modal parameters and to dynamic responses.

The control of the concrete manipulator is a challenge, considering its highly nonlinearity and coupling and the uncertainty from the internal and the external, which will effect the efficiency directly. In this paper, the kinemics and dynamics of the whole concrete delivery manipulator are analyzed firstly. An advanced control strategy, nonsingleton fuzzy neural network, is utilized on concrete delivery manipulator for the first time. Then the simulation study is conducted based the Simulink. It can be found that the establishment of dynamic model is appropriate and the proposed NSFNN controller can follow the target signal better. The result shows that the NSFNN controller can solve the uncertainty to some extent in the constrain of the frame of the type-1 logic fuzzy control.

Concluding that the grinding near the pin rod and the cylinder wall is more fully obtained. With an appropriate speed, the grinding structures near these areas can be optimized to enhance the grinding effect.

ABAQUS, as a large-scale non-linear finite element analysis software, is widely used in mechanical engineering structure calculation. Among them, the plastic damage model of concrete is recognized as the most effective model to simulate the inelastic behavior of concrete under repeated loads. It is widely used in the time history calculation and analysis of high-rise buildings, In mechanical engineering, this model is also needed to study the failure mechanism of mechanical cutters on concrete. But in the application of ABAQUS concrete plastic damage model, users need to input the tensile and compressive damage factor-inelastic strain parameter table. ABAQUS does not give the corresponding parameter table of concrete with different strength. Based on the research results of the former and the uniaxial constitutive relation of concrete recommended in the Code for the Design of Concrete Structures, this paper further studies the fitting equation of the tensile and compressive damage factorinelastic strain curve of various strength concrete by means of numerical analysis method, which makes up for the vacancy of ABAQUS and makes the plastic damage model of concrete more suitable and more accurately. The damage factor equation under this study can provide an effective reference for concrete research and greatly facilitate the concrete analysis of later scholars.

Supply pressure control of the aircraft hydraulic pump is of great importance. However, the pressure control system of variable displacement axial piston pumps is significantly affected by fast changing, unknown loads and time-varying parameters. In the present paper, PID control strategy based on BP neural network was proposed to improve the tracking performance of the piston pump outlet pressure. First, the working principle and the mathematical model of the aircraft variable pressure hydraulic system are described. Then the architecture of the BP neural network and the structure of the PID controller are established. In this control strategy, the PID controller parameters kp, ki, kd can be adjusted online through the neural network in order to achieve an excellent control effect. Finally, simulation results demonstrate that there is a good supply pressure tracking performance under the proposed control strategy.

The Internet has promoted the development of the sharing economy, and construction machinery is usually leased because of its high price and single use. In order to find a suitable supplier, it is necessary to evaluate the supplier according to information of construction machinery from the Internet platform. This paper proposes a method to select construction machinery suppliers by real-time and historical data. Firstly, the evaluation index of construction machinery quality is established. Secondly, the weight of each index is determined by entropy AHP. Thirdly, the service capabilities of each supplier are sorted by grey correlation analysis. Finally, we take ten excavator suppliers as example, and illustrate the basic steps of the quality evaluation of construction machinery. Further, this evaluation method also provides reference for selecting cloud service provider and matching service.
