摘要
本文研究了200型柴油机转动惯量的分布对自振频率的影响,提出了集中质量订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,使系统的自报频率不但不下降,还略有提高。
Effect of rotary inertia of type 200 diesel engine on its natural frequency has been discussed.and conclusion drawn that the concentrated mass has a greater effect on l-node natural frequency than the distributed mass.Presupposing that the total inertia of existent system being kept unchanged,and with the crankshaft fitted with balance weignt,slight increase,instead of decrease.in the natural frequency of the system can be expected through adjustment of flywheel inertia.
