摘要
拖拉机挂车机组工作时的动态载荷按其频率结构可分成四类。本文着重讨论了第二类和第三类载荷的识别方法及其对发动机工作的影响,识别结果与试验基本相符。探讨了一种发动机动态运用载荷系数的选择方法,给出了动态运用载荷系数的工程计算用的经验公式。
The dynamic loads of engine in tractor-trailer unit are classified into four kinds with frequency structure. In this paper, how to distinguish between the second and the third kinds of load and their effects on behaviour of engin e are discussed in particular, with the analyses comforming to experiments. The method for determining the load coefficient is pretented. And the empirical formula used to calculate the coefficient in engineering is given out.
