Kinematic pairs clearance of cam mechanism has an important effect to system dynamics response of Gatling gun. In order to study effecting law of driving clearance to Gatling gun's system resistance moment and core's force, based on dynamics theory of mechanism system with clearance, and through analyzing motion and force of cam drive mechanism, dynamics coupled equation of cam mechanism with clearance is built by Dubowsky's impact model. It discussed the effect of cam drive clearance to Gatling gun's dynamic characteristics using ADAMS emulation analysis. The calculating result indicates that to reasonably control cam drive clearance is the important factor to reduce Gatling gun's system power loss and system resisting torque.

This paper concerns the digital watermarking technology on three different processing stages in order to enhance the robustness of digital watermarking under the premise of invisibility. (1)The first stage is watermark signal pre-processing. The watermark signal created using binary gray images is taken the highly nonlinear processing by the chaotic function first and then by the neural network, which enhances the degree of watermark confidentiality greatly; (2)The second stage is watermark embedding strength degree. First a neural network is constructed and trained. The trained neural network can be used in watermark embedding and extraction by which a watermark algorithm can be achieved to do blind detection; (3)The third stage is watermark embedding and extraction. The treated watermark signal is embedded into the airspace of the original image through the trained neural network. And the neural network is also used to extract and detect the watermark. Proved by experimental results, this algorithm has good robustness.

At present, the design of port machinery is mainly relied on the method of static design. It sometimes makes the design unprecise and unreasonable. On the basis of vitual prototype technology, this paper takes adventage of Solidworks to build a boom system model of the 40t/33m protal crane. Then inport the model into Adams for the dynamics simulation analysis. At last, we get the variation curves of several hinge-forces(take hinge-forces for a example because it is important in the crane design and complex and unprecise by the former methods) in luffing process. From the curves we obtain the maximum values and in which radius and situation the maximum value occurs.

In order to enhance openness and flexibility of industrial robot control system, an open control system based on double-CPU was designed. An embedded industrial computer based on ×86 CPU with Windows XP worked as the upper-system, which implemented HMI and management of the open control system. A FPGA(Field Programmable Gate Array) and another same embedded industrial computer with RT-Linux worked as the lower-system, which implemented realtime motion control of the open control system. Ethernet based on a user-defined Ethernet type was used for exchanging data between the two CPU. Experimental results of the open control system being used for controlling a 5 DOF(Degrees of Freedom) flexible-joint manipulator demonstrate that performance of the system can satisfy requirements of different industrial robot application.

Energy saving is of great importance and energy-efficient optimal is considered as a critical element in battery design. In this paper, a novel static voltage scheduling algorithm for battery-aware dynamic voltage scaling (DVS) systems is presented. The proposed algorithm pays fully attention to the relationship of the factors (the increase of the slack time and discharge) related to battery consumption by taking the nonlinearity characteristics of the battery into account. We focus on the decreasing speed of the cost function which is a critical parameter in energy saving. The proposed algorithm can get the fastest speed in cost function decreasing and finally return a profile in accordance with the profile obtained by brute-force searching. Aperiodic and periodic tasks on uniprocessor and multiprocessor are considered in the proposed algorithm to make our algorithm widely used.

A simulation method for dynamic response analysis of mooring system based on virtual prototype technology is presented according to its characteristics of multisystem coupling and nonlinearity. Anchor chain is regarded as catenary to get the initial conditions of mooring system through its static analysis. According to the dynamic analysis of mooring system, we apply Morrison equations to simplify the mathematic analysis model of mooring system, and solve it using perturbation method. Mooring system fits a nonlinear system according to the experiment data in different conditions, and is simplified to nonlinear spring constraints to construct a virtual prototype model of offshore platform in ADAMS software. Its feasibility of dynamic analysis based on virtual prototype technology is demonstrated by an application example showing the simulation analysis of grab dredger. The simulation results show that the simplified model of mooring system provides a reliable analysis platform for the virtual simulation of offshore platform, and decrease its analysis complexity of the theory research on dynamic performance.

Owing to the tamping mechanism of asphalt paver, the shocks towards flatiron-box are produced by compound motion of tamping beam. This significantly influences the road paving quality. In this paper, we adopt the multi-mechanical system simulation software ADAMS to establish the dynamics model of the tamper mechanism, and carry out the analysis of the mechanism based on virtual prototyping technology. Through the simulation analysis of tamping mechanism, we can get the impact regularity of the vibrating beam inertia force and moment of inertia as a result of the vibration frequency and amplitude. It provides a reference for the design of tamping mechanism for paver and the adjustment of construction parameters.

Active front steering (AFS) system has been the trend of steering technology in recent years by improving the steering comfort and active safety. In this paper, a new layout AFS system combining column mounted AFS actuator with pinion-type electrical power steering (EPS) system is proposed and its dynamic characteristics are analyzed. Three typical variable gear ratio (VGR) actuators are discussed in detail, including a new VGR actuator proposed. Then, the mathematic dynamics formulas of all main parts of the AFS steering system are induced. With Laplace transform, the block diagram model of each part is introduced. The whole dynamic block model of AFS system is built by combining each part's block systematically. Simulation of the model developed by using PID feedback control is conducted in the environment of Matlab/Simulink to verify the proposed AFS system model.
