Dynamic Characteristic Study As A Whole Of High-Speed Tire Experiment Machine

Through the modern theory of mechanical design, dynamic approach to the complex structure of the sub-mechanical systems - high-speed tire experiment machine for dynamic analysis, simulation models, structural changes and dynamic optimization has been achieved.According to the dynamic substructure method can be divided into high-speed tire testing machine to rack and wheel. Tire Rack which is a high-speed test bench important component of its direct impact on the performance test-bed in the high-speed, high-load of security, reliability. Through the ANSYS software for dynamic analysis of the calculated rack dynamic targets. The hub, based on the statics and through finite element software ANSYS secondary development of the APDL had linguistic ANSYS order flow establishment, the establishment of a Renzi Jia structural parameters of the finite element model, circulation and use of statements extracted branch Renzi Jia Roll movement in the process of a different magnitude of stress and strain in an important position and image of the stress changes in the curve, Renzi Jia realized the structure of the movement simulation; Finally, ANSYS and Pro / MECHANICA drum on the structure of dynamic analysis to be Point of low-level mode and vibration mode, an analysis of the structure of the main parameters of the drum dynamic characteristics of the end of the drum to determine the reasonable parameters of the structure.Based on the wheel and rack dynamic analysis, confirmed the rack and wheel bound manner, the paper also high-speed tire testing machine and rack wheels are calculated as the overall analysis, modal analysis found that high-speed tire testing machine Overall first-order natural frequency not only with the constraints, but also with the constraints and access to relevant way. In meeting the natural frequency, intensity, stiffness, and other required conditions, so that the high-speed tire testing machine and the wheel rack of the quality of the smallest, is another research paper topics. First of all, to identify constraints in the way, the use of finite element analysis on the mode wheel rack and had a dynamic and static analysis, has been high-speed tire test platform for the overall deformation, stress and vibration mode and frequency bands.
