| 摘 要： | 以国际ＧＢ４９７０（修订稿）中载货汽车货厢振动的检测方法为基础制订了货厢振动等级及其限值的方法，其中包括样本的建立和分布检验，确定评价等级与制定限值线等，并举出了应用实例，由于采用等级和加速度均方根值的车速特性评价货厢的振动水平，所以既方便又合理。

| Abstract: | Based on the measurement and inspection method of medium duty truck body vibration in the national standard GB 4970 (modified version),the article presents in detail the method of instituting class and limit for truck body vibration, which includes setting samples and examinating their distribution, determinating grades of evaluation and formulating the limitation line etc., and also giving out example of application. As the truck speed mean square root value of acceleration are used to evalute the truck body vibration, the evaluation method has been instituted not only easy to use but also rational. |
