摘　　要：针对公司开发的某款7m前置校车出现怠速共振的问题,利用Adams仿真软件对其动力总成悬置系统进行解耦计算,然后进行优化设计,减轻了发动机的怠速共振,满足公司的测评标准要求。Aiming at the problem of idling resonance for a 7 m front-engine school bus developed by the author’s company,the decoupling calculation of its powertrain mounting system is carried out by using simulation software,and then the optimization design is carried out. The result is the idling resonance of the engine is reduced and meets the requirements of the company evaluation standard.

关 键 词：前置校车 动力总成 悬置系统 怠速共振
