摘　　要：悬置系统的减隔振性能与悬置的刚度、安装位置和安装角度直接相关,悬置系统的匹配效果决定减隔振性能。以设计难度较高的搅拌车低怠速发动机悬置系统为例,建立系统动力学和能量解耦计算模型,通过案例和实测结果分析验证模型和方法的有效性。研究结果表明所建立的计算模型和分析方法能够显著提升悬置系统的减隔振性能。The vibration damping and isolation performance of the suspension system is directly related to the stiffness,mounting position and mounting angle of the suspension,and the matching effect of the suspension system determines the vibration damping and isolation performance.Taking the suspension system of the low idle engine of a mixer truck,which is difficult to design,as an example,a dynamics and energy decoupling calculation model of the system is established,and the effectiveness of the model and method is verified through the analysis of cases and test results.The research results show that the established calculation model and the analysis method can significantly improve the vibration damping and isolation performance of the suspension system.
