摘　　要：汽车零部件单件及总成公差设计的目的是保证功能目标的实现,因此公差设计方法的基本流程是先对零部件单件及总成进行功能分析;然后通过尺寸链等辅助工具将目标公差分解到每一个影响功能目标的链环上;最后综合考虑工序能力评估和工艺成本优化定义出合理的公差,最终实现功能目标。研究过程与结论对于汽车零部件公差设计方法建立具有参考意义。The purpose of tolerance design for single parts and assemblies of automobile parts is to ensure the realization of the required functions.Therefore,the basic process of tolerance design is to analyze the functions of single parts and assemblies,decompose the target tolerance to each link ring that affects the target function of the requirement through auxiliary tools such as dimension chain,and then define a reasonable target tolerance through comprehensive consideration of process capability evaluation and process cost,so as to ensure the realization of the final function.
