摘要

汽车衡秤体挠度过大是引起其测量误差的主要原因。将钢结构预应力处理法运用于秤台与U型梁的焊接工艺过程,建立秤体挠度和应力随着预加载荷变化的数学模型,基于有限元法实现秤体预应力处理过程。结果表明:秤体挠度的模拟结果与数学模型的变化规律一致。因此,钢结构预应力处理法的应用能有效提高秤体刚度,进而提高汽车衡的测量准确度。

Abstract

Excessive deflection of the truck scale body is a primary cause leading to measurement error. The prestressedtreatment method of steel structure was applied to the welding procedure of the truck scale body and U-beam. The mathematical relationship model between the preload and the deflection and stress of the truck scale body was constructed. In addition,the prestressed-treatment process was carried out based on finite element method. The results show the deflection of the simulation results is consistent with the changing rule of the mathematical model. Therefore,the deflection of the truck scale body can be improved effectively with the prestressed-treatment method of steel structure,which can be able to improve its measuring accuracy.
