摘要
详细叙述了Lagrange方法的理论体系;针对一种平面双摆机构进行了动力学分析,采用Lagrange方法建立动力学模型;结合纽马克法,用VC++编制了自动建立平面双摆机构动力学模型的计算机程序,通过MATLAB软件模拟了平面双摆机构模型微振动时旋转角位移的动力学响应情况;从而为这种机构动力学特性的深入分析和结构优化设计提供了参考。
It describes the theoretical system of Lagrange＇s method detail. Based on Lagrange＇s method,dynamics was analysed and the dynamic equation of aplane double pendulum model was established. Combinated with Newmarkmethod,a VC＋＋ computer program,which can create dynamic equation automatically of the plane double pendulum model,was produced. Computer simulation of MATLAB was pe^ormed to investigate the dynamic response situation when the plane double pendulum model is microvibrating. The results provided references for, detailed research on dynamic characteristics and optimal design of the plane double pendulum model.
