Academician prof zhong wan - xie presented precise integration method firstly in 1993 , and ordinary differential equation can be solved precisely by this method . in this article , improved precise integration method is given firstly . then on the basis of improved precise integration method , a new method for calculating the response of dry friction system is presented , and the calculation precise degree of this method is tested by the comparison with ihb method
1993年钟万勰院士提出了精细积分法，它可以精确求出常系数常微分方程的数值解，本文首先提出精细积分改进算法，进一步提高了其计算精度，然后在改进的精细积分法基础上对于摩擦系统响应的计算方法进行了研究，并用ihb法对这种计算方法的计算精度进行检验，结果证明这也是计算干摩擦隔振系统响应的有效方法之一。
