摘要
汽车在行驶时的振动是一个复杂现象。欲模拟汽车的振动,首先应该建立1个能尽量反映汽车实际振动状况的数学模型,将车辆看作1个多自由度振动体系,把汽车简化到由质量块代表车体和轮轴质量、弹簧和阻尼器代表轮胎和减震系统,从而通过能量法建立汽车本身的振动方程。
When a vehicle is driving, its vibration is very complex. Firstly, to simulate the vibration of a truck, the mathematic model that reflects considerably the actual vibration performances should be established. This paper views a truck as a multi-freedom vibration system, simplifying a truck by standing for masses of vehicle＇s body and wheel axle with mass blocks, and standing for tyre and absorption system of vibration with elastic spring and shock damper. Consequently, the vibration equation of vehicle has been established with energy method.
