发动机悬置系统优化设计

Optimization Designof Engine Mount System

以某大功率柴油发动机悬置系统为研究对象,为了解决整机振动烈度和隔振效率这一对矛盾,应用振动理论和最优化原理和方法,将设计问题由物理模型转化为能反映实际问题和设计要求的悬置参数的优化数学模型,并采用适当的优化算法,求解数学模型,得到悬置系统的优化设计参数,为发动机减振技术研究提供修改意见。

In order to solve the contradiction of the engine s vibration severity and vibration efficiency of a high power diesel engine s mount system,theory of vibration and optimization are used to translate the physical model of the design problem into optimal mathemati cmodel which can reflect reality and parameters of the requested mount system.On these bases,a reasonable optimization method is used to solve the mathematical modal and the engine mount system s parameters are optimized.The results give amended op...
