摘要
基于产品设计中的尺寸管理思想,结合计算机仿真分析软件VSA和分析技术,对塑壳断路器的触头超行程理论值进行公差分析。通过预测和控制制造偏差、优化设计,提高了产品尺寸、质量,降低产品生产成本。
Based on the thought of dimension management in product design,also combined with computer simulation software VSA and analysis techniques,the tolerance analysis on the theoretical values of contact over-travel was made as taking moulded case circuit breaker（MCCB） for example.the dimension quality of the products was improved and the production costs by forecasting and controlling production deviation and optimizing design were decreased.
