车辆传动系是一个小阻尼的非线性系统 ,具有不同分系统之间相互动态作用的多自由度。具有许多激振源 ,如在动力传动链中的间隙形成的扭转冲击 ,这样的激振源存在于传动系花键和差速器内的小齿轮对冠齿轮的传动间隙中。在慢速行驶中突然增加和释放油门或离合器的快速接合都可随之带来噪音和振动响应 ,涉及工业中的‘微冲’。本文介绍一种车辆传动系的模拟方法 ,它可以证实大家熟知的微振‘Clonk’和‘慢动’现象。这种模拟是以车辆传动系可认为部分集总和部分分散的假定为基础 ,而对于这种装置是完全合适的。由此可以导出控制方程式的一个分析解 ,这是过去不曾研究过的。由该模拟求得的结果与可比车辆传动系总集成模型相比较。
The vehicle driveline is a small, damped, nonlinear system with multiple degrees of freedom in the dynamic interaction between different subsystems. There are many sources of excitation, such as torsional impacts created in the gaps in the power train, which are present in the drive sprocket and pinion-to-crown gear drive gaps in the differential. Sudden increase in slow driving and release the accelerator or the clutch can quickly bring the noise and vibration response, involving the industry’s ’micro-red’. This article presents a simulation of the driveline of a vehicle that confirms the well known micro-vibration ’Clonk’ and ’slow’ phenomena. This simulation is based on the assumption that the driveline of a vehicle may be partially decentralized and completely suitable for such a device. From this it is possible to derive an analytic solution to the governing equation that has not been studied in the past. The results obtained from this simulation are compared with the total integrated model of a comparable vehicle driveline.
