摘要：利用能量解耦法对北汽福田BJ1049轻卡动力总成悬置进行优化，在不改变悬置安装位置及安装角度的情况下，通过改变悬置软垫三方向刚度值，使动力总成空间六自由度运动方向能量相互解耦，减小动力总成振动向外界传递。

Abstract: Using Energy decoupling method to optimize powertrain mount of Beiqi Foton light truck BJ1049. Under the condition of without changing suspension installation position and angle, through changing three direction stiffness value of suspension cushion, causing energy of six freedom degrees movement directions in powertrain space are mutual decoupling, decreasing the the world pass of powertrain vibration.
