Dynamic Model and Simulation Analysis of a 3-DOF Parallel Mechanism

In order to study the dynamic response of shipborne missile vertical launching under high-wave-level environment, the rigid-flexible coupling dynamic model of launching system was built by ways of virtual prototype technology. According to simulations for different launching conditions, missile attitude parameters were acquired, and interference of various parts was analyzed. The result shows that the dynamic model and simulation method proposed in this paper are effective and practicable.

Model And Simulation

This paper presents a novel Rotary Steerable System which used a universal joint to avoid the alternating press in the drilling process. The mechanics model is established on the basis of simplifying structure and supporting of rotation axis in directive RSS. Dynamic model of the offset mandrel is derived by means of Hamilton principle, which could be used to control system design. Location of offset force acting on the offset mandrel is optimized and vibration equation of universal joint is deduced by means of transfer matrix method, then the results of natural frequency are compared with the calculated results of the finite element to verify the kinetic model. Both dynamic model and simulation analysis are expected to provide useful good guidance for the design of control system, detail design, structure optimization and the dynamic vibration of the RSS.

Unloading Time

This paper mainly analyzes the hydraulic system principle during the monorail braking, and come to a conclusion that the spring stiffness and the throttle valve flow area are main factors affect the brake system. Then we use the MSC.EASY5 to modeling the hydraulic system, and simulate the unloading time of hydraulic cylinder under the spring force, the result shows that, the response time of a braking system can meet the requirement of the coal mine safety regulation, and change the flow area of throttle valve will affect the brake system.
