摘要
本文研究了200型发动机配重的质量分配对自振频率的影响,提出了集中质量对单节频率的影响比分布质量要大的结论.在保证原系统总惯量不变的前提下,当曲轴配置平衡重后,可以通过调整飞轮惯量,使系统的自振频率不但不下降,还能略有提高.
After discussing the effect of the balance of 200-type diesel engine on its natural frequeucy, this paper draws a conclusion that the concentrated mass has a greater effect on 1-Node natural f equency than the distributed mass. In a certain inertia of the system, the natural frequency can be increased a little by adjusting the inertia of the flywheel when the crankshaft is fitted with a balancer.
