摘要
以额定转速为2 400 r/min,额定功率6 KW柴油发电机组为试验样机,对带有橡胶隔振器的机组振动性能进行研究。采用有限元法得到了机组的固有特性和振动响应,分析了隔振器参数变化对机组振动性能的影响。结果表明:隔振器橡胶杨氏模量和阻尼系数增大到一定数值后,对机组的振动起到良好的抑制作用,隔振器两端的振动差距部分缩小,其它呈增大趋势。
Vibration properties of diesel generator set with a rubber isolator were investigated,which has a power of6 KW and rated speed of 2 400 r / min. Inherent characteristics and dynamic response of the units have been acquired by finite element method( FEM). The influence of different parameters of isolator on vibration properties of diesel generator set was analyzed. The results show that when the Young's modulus and damping coefficient of the rubber isolator increase to a certain value,vibration amplitudes of the units are inhibited well. Except this,vibration gap at both ends of isolator is narrowed in part,and the other trends to increase.
