Abstract: Virtual assembly is one of the main contents of the virtual manufacturing; assembly process simulation is an important part to product virtual assembly. The establishment and optimization technology of three-dimensional assembly simulation scene have been studied to develop a virtual machine assembly simulation system, which achieve a virtual simulation of assembly and disassembly of the machine and the integration and improvement of existing collision detection library, design and implement a graphical simulation system collision detection module, which can real-time interference checking to machine parts motion. The system has good human-computer interaction and visual interface, versatility, can be applied to any organization's assembly simulation, and through examples of the validity of the system.

Abstract: The structure of the sensor endurance test station is designed. Satisfied with the request of the performance, structural parameters of the spindle and bearing are calculated to minimize the spindle mass using optimization theory. By the static analysis, fatigue analysis and frequency analysis of spindle and bearing using the FEM, the simulation results indicate that the optimized structures can meet the demands for the strength and dynamics of the flywheel system, which leads to safe and stable work, improve design efficiency effectively, shorten design cycles, and reduce production costs. In order to reduce the eccentric force of inertia and intensity of the vibration source, the need for computing unbalance spindle, and a mechanism for balancing, allowed reaching equilibrium precision. After commissioning test station, running at high speed working in good condition, system run more smoothly, to meet the requirements.
