Abstract

Tolerance analysis of mechanical assemblies is an important tool in reliable design of products at low cost and good quality. Using this tool, it is possible in manufacturing stage to observe the effect of parameters on assembly requirements. The direct linearization method is a useful method which runs based on vector loop analysis. In this research, the DLM method is used to analyze the tolerance chain in triggering mechanism assembly. Furthermore the percent contribution of various manufacturing dimensions on the design requirement of the assembly in determined.
