摘　　要：利用VB开发的柴油机单层隔振系统隔振参数优化软件,以振动理论为基础,采用柴油机隔振参数对比优化的方法,计算柴油机离心力、简谐颠覆力矩、固有频率和振幅,通过柴油机的共振频率和振幅的计算比较,分析不同隔振器的隔振效果,选择隔振效果最优的方案。研究结果表明:柴油机隔振参数对比优化的方法,能够避免单一型号隔振器在柴油机隔振优化时,隔振参数优化效果没有其他隔振器好的错误;可使柴油机的减振效果最优化,且优化计算的时间短、效率高。VB was adopted to develop the software for the optimization of single layer vibration isolation system parameters of diesel engines, based on vibration theory, using the method of diesel engine vibra- tion isolation parameters comparison optimization, the diesel engine centrifugal force, harmonic overtur- ning moment, natural frequency and amplitude were calculated, through the resonance frequency and the amplitude comparison, vibration isolation effects of different isolators were studied, and hence the best vi- bration isolation programme was selected. The research results show that, the parameters comparison and optimization method of vibration isolation of diesel engine could be used to avoid the problem that when u- sing a single type vibration isolator, the optimization effect is worse than the ones of other vibration isola- tors, thus ensures the best optimization of vibration isolation, and achieves quick calculation and high el-ficiency.
