实践表明,用力法计算底架,只要计算过程不过分简化,其结果是能相当准确地反映实际应力的分布情况的。而对于车体(指底架以上部分,多属薄壁结构)用现在简易的计算方法所得结果,则一般与实际应力相差太大,但此缺陷可以利用设计规范中比较齐全的约束数据来弥补。所以,底架的力法计算对于车体设计是有着实用意义的。本文 Practice shows that the force method to calculate the chassis, as long as the calculation process is not too simplistic, the result is able to fairly accurately reflect the actual stress distribution. For the body (referring to the chassis above the part of the mostly thin-walled structure) with the present simple method of calculation of the results obtained, the general and actual stress is too much difference, but this defect can use the design code more complete constraint data to make up . Therefore, the method of calculating the chassis for the body design is of practical significance. This article
