摘要
研究了一般形式的弹性连杆机构的动力稳定性问题，在忽略结构阻尼的情况下，从理论上研究了低价临界转速的分布规律，给出了低价临界转速与机构一个运动周期固有频率平均值的显式关系表达式。用这一关系式求得的低价临界转速和数值方法得到的识别结果进行了比较，说明了本文方法的有效性。
In this paper, the dynamic stability problems are investigated for flexible linkage mechanism systems. The distributions of the unstable running speeds of the system are studied based on the Floquet theory. The explicit relationships between the unstable speeds and the average frequencies of the system in a period are derived. The relationships are suitable for any flexible linkage mechanism system. Numerical verification for the relation obtained in this paper is provided.
