摘要
建立了一种求解非对称系统周期性动力学响应的数值方法,该方法不局限于具体的机械系统,而是由非对称系统动力学方程的特点推导而来,具有普适性,可应用于求解复杂机械系统的动力学响应。最后通过算例分析验证了该方法的有效性。
A numerical closed-form algorithm is established to solve the solutions of asymmetrical systems periodic dynamic response. This algorithm is not deduced from a specific mechanical system but from general dynamic equations, so that it has universality and can be utilized to calculate dynamic response of complicated mechanical systems. The algorithm is analysed by an example, and its validity is proved.
