摘要
通过对某二轮摩托车振动信号的在线测量和摩托车架的试验模态分析，找出了摩托车发生共振的原因及其共振频率。本文首次将最大熵优化法用于工程结构──摩托车架的优化设计，这是一个有尺寸、应力及频率约束的动力优化问题。自编程序，在ＶＡＸ型机上经４次迭代得最优解。
The resonant causes of the motorbike and the resonant frequencies were found by measuring the vibratory signals of a two-wheel riding motorbike on line with telemeter and the test model analysis of the frame. In this paper, the maximum entropy optimum method was first induced the engineering structures──optimum design of motorbike frames.This is a dynamical optimization problem with sizes, stresses and frequency constraints. The computing programme was made by oneself,and the optimum point has been obtained through 4 iterations on VAX.
