基于电路模拟解决多杆机构弹性动力学建模问题

Circuit Simulation and Solution to Flexible Organization Dynamics

多杆机构的弹性动力学的传统建模方法采用拉格郎日第二类方程、虚功原理和有限元方法建立,针对传统建模方法相对复杂等问题,提出了应用电路模拟方法解决多杆机构的弹性动力学建模问题。从研究电学与机械振动学数学相似性入手,研究了一个等值电路,归纳了电路模拟建模方法的一般规则,并应用上述原理解决了多杆机构的弹性动力学建模问题,给出了一般求解公式。

Traditional modeling methods in the flexible dynamics analysis always apply the Second Lagrange Equation, the principle of virtual and finite element method. In the traditional method, the model establishment of flexible dynamics, broad sense force ,broad sense coordinate and the relation conform of broad sense coordinate are relatively complex. In allusion to these problems the article puts forward a new flexible organization dynamics modeling method and applies this method to resolve the modeling of many_ pole organizations of the flexible dynamics.
