基于激光测量的汽车零件间隙面差计算方法

摘要

提出了激光测量汽车零件间隙处的数据前处理方法和步骤。根据汽车零件间隙面差的定义，分析其几何结构，提炼了间隙面差计算的数学模型，并通过用基准块和实际工程零件的检测，验证了其计算精度。可为自主研发汽车检具激光检测系统做准备。%Pretreatment methods and steps for the gap testing of automobile parts by laser are proposed. Based on the concept of gap and flush,the geometry structures are analyzed and the mathematical model of gap and flush is estab-lished. In addition,the calculation accuracy is verified through experiments of reference block and engineering parts.The method can be used to research and develop laser measurement system for automobile parts testing and fixing.
