商用车试制PT至SOP快速验证方法研究

目前商用车的开发主要分为骡子车试制、工程试制和试生产几个阶段,与乘用车不同,商用车存在车型配置繁多,而且不同的配置之间可能会对整车在底盘的布置产生影响,进而影响整车在量产线的通过性,因此有必要在PT(工程试制)和SOP(试生产)阶段间加一个验证阶段,文章首先介绍了PT转SOP试制线的布局及工艺编排,然后对PT转SOP快速试制验证流程进行了介绍,最后对PT转SOP量产通过性的判断指标进行了说明,对PT车型如何更好的过渡到量产,减少量产线的停线及线下返工具有一定的参考意义。

Commercial vehicle quick examination research from PT to SOP

Divided into 3 processes as mule vehicle trail,engineering trial and production trial,commercial vehicle is different from PVs,there are too many commercial vehicle types,and the different dispositions may lead the effect on the chassis,finally it will impact the throughput capacity in the volume production line.Therefore,we need to add a examination stage between PT&SOP.This article is into 3 parts,first is the introduction of production line layout and technology arrangement,second is the quick trial examination introduction,last is the discrimination of PT to SOP throughout examination which is meaningful for the transition of PT to SOP,stopping line time waste reduction,and repair work off-line guidance.
