摘　　要：利用ADAMS软件建立某型叉车整车在怠速工况下的振动仿真模型,并进行实验验证,实验表明通过采用对连接螺栓的柔性化方法可以有效提高叉车仿真模型的准确性。在此基础上利用ADAMS试验设计方法,对整车动力总成悬置刚度阻尼匹配进行优化,结果表明通过刚度阻尼的合理匹配能在一定程度上改善整车车架上的振动情况。The model of a forklift truck is built for vibration simulation in idling condition by means of ADAMSsoftware. The result of simulation is verified experimentally. It shows that the accuracy of the forklift truck simulation can beeffectively improved by raising the flexibility of the bolt joints. On this basis, the match between stiffness and damping ofthe powertrain suspension of the forklift truck is optimized by using ADAMS software. Results demonstrate that thereasonable match between stiffness and damping can improve the vibration condition of the truck.
