摘要
建立内燃机悬置系统的动力学模型,以刚体模态的解耦率及频率合理分布为优化目标,运用Matlab编制解耦率和模态参数的计算和优化程序,以实例验证优化方法和计算优化程序的实用性,为内燃机悬置系统的设计提供参考。
The dynamic model of the internal combustion engine mounts system was established. By discussing the decoupling rate and the frequency distribution of the rigid body modal, the basic optimization method of engine mounts system was presented. Based on this method, the computation codes were programmed in the Matlab environment. In order to verify the practicability of the method and the program, a typical case was demonstrated in detail.
