【摘要】 根据汽车车身薄壁件的功能要求，推出了车身薄壁件采用形位公差的必要性，并指出了现行形位公差用于车身设计时所存在的问题。在对现行形位公差标准进行适当补充的基础上，建立一个比较切合实际和较为完善的汽车车身薄壁件形位公差体系，并在南京汽车制造厂得到实际应用。更多还原

【Abstract】 篈ccording to the functional requirements of auto thin-wall body parts, the neccesity of adopting the shape and location tolerance for the thin-wall body parts is presented in this paper, the problems of currently-used shape and location tolerances for body design are also presented. On the basis of moderate supplement for the currently-used shape and location tolerance, an actual and more perfect shape and location tolerance system for auto thin-wall body parts is deve loped and is in application in Nanjing Automobile Works.更多还原
