刚弹耦合建模在汽车转向轮摆振问题的应用 总被引:6,自引:0,他引:6
为了增加模型的准确性,考虑悬架承载体系统对轿车转向轮摆振过程的影响,采用刚弹耦合建模的方法解决转向轮摆振问题,即将多刚体系统动力学分析软件(ADAMS)和有限元分析软件(MSC/NASTRAN)相结合的方法进行建模。将汽车悬架多刚体动力学模型的仿真结果、多柔体动力学模型的仿真结果与道路试验数据相比较,结果表明刚弹耦合建模的方法能更有效地研究转向轮摆振。 相似文献

A conveyor belt driven by wound rotor motors produces dynamic tension, velocity and acceleration during starting. The terrible situation (such as resonance) in dynamic analysis and design is that system natural frequencies are equal to those for switching off electric resistances. This paper analyzes and determihnes system natural frequencies based on a modeling method of receptances with the analysis of sub-systems model and of the principle of their addition and conveyor loop closure. It also puts forward to calculate the time interval for switching off electric resistances. The starting of one conveyor is simulated by lumped-mass-spring-model software to further illustrate the influence of time interval for switching off electric resistances on conveyor dynamic behavior. Two methods are also compared. The receptance model is proved to be an excellent alternative. 相似文献
