摘要
通过研究结构参数、齿轮参数对临界转速的数量、分布及其对应的对数衰减率的影响发现 ,在齿轮耦合的转子 -轴承系统中 ,临界转速非常密集 ;在系统达到工作转速之前 ,必须跨越许多临界转速 ;合理地选择系统参数 ,可使最小对数衰减率增大 ,使系统表现出较强的阻尼特性 。
The influence of the gear parameters and gear position on amount, distribution of the critical speed and its logarithm decrement is researched. It is found that in a geared rotor bearing system, before reaching the working speed, many critical speeds must be overcome. When the system parameters are selected reasonably, least logarithm decrement will increase, and more damping will appear in the system, which is advantageous to overcome the critical speed.
