摘　　要：分析了发动机悬置系统振动特性,建立了悬置系统振动数学模型,给出了悬置系统固有频率和主振型的计算方法,提出了采用双直线型隔振元件的发动机悬置系统,通过合理选择隔振元件弹性系数,能使发动机悬置系统的隔振性能得到提高.The vibration characteristic of engine mounting system is analyzed, the vibration model of engine mounting system is established, and calculation method of natural frequency and main vibration mode of mounting system is put forward. Then an engine mounting system with double - lined type isolator is presented. Isolation performance of engine mounting system is improved greatly by selecting elastic coefficient of isolator reasonably.
