摘要
由表面接触理论,在MSC.ADAMS中建立了包含多个实体相互接触的链传动多体动力学模型。针对多接触问题的求解需时量大,提出了以近似力代替接触力的模型简化方法。该方法的求解速度提高一倍以上,并在一定程度上减小了仿真的整体误差。对链传动的机构优化分析及整机仿真提供了合适的虚拟样机模型。对于带传动、履带传动等同类模型的优化提供了方法和依据。
Multibody dynamics model of chain drives including objects＇ contact was established by MSC. ADAMS software base on the contact mechanics theory. In view of the long time simulation as multi-contact was involved, the method to simplify the situation by replacing the contact with approximate force is proposed, which speeds up the simulation beyond one time, and to some extent reduced the simulation overall error. It provided the appropriate virtual prototyping model to the chain drives＇ mechanism optimization analysis and the whole machine simulation, and offered optimization reference for similar models sach as belt drives and track drives.
