摘要
针对某皮卡车振动剧烈、噪声较大等问题,建立动力总成悬置系统多体动力学模型。通过模态分析、动力总成质心加速度和悬置支撑处响应力的仿真,优化悬置的主刚度,使其隔振效果得到明显改善,不仅提高了车辆乘坐的舒适性,而且延长了发动机与其他部件的使用寿命。
Aiming at some problems that one pickup＇s violent vibration and the greater noise etc.To build the multi-body dynamic model of powertrain mount system.The mounting＇s stiffnesses are optimized by modal analysis,powertrain centre of mass acceleration and mounting response force simulations.Its vibration resistance performance is improved markedly.It is not only improve the comfortability,but also prolong the durability of engine and other components.
