Analysis of the anti-vibration qualified rate of relay considering manual debugging process

As an important switching device, the relay's mechanical resistance has been receiving much attention. However, the manual debugging process has an important impact on it. This article starts with the analysis of manual debugging factors that affect the anti-vibration qualification rate. The quality characteristic parameters of the debugging process and their thresholds that affect its anti-vibration qualification rate are obtained by designing contrast tests. Secondly, the object's qualitative characteristic parameters and debugging parameters are constructed by a approximate calculation model based on the virtual prototype. Finally, the impact of manual debugging process on product quality characteristics is analyzed. And suggestions on the parameters to be controlled by manual debugging are given. The adjustors strictly control the parameters of the debugging process according to the above suggestions. And the current qualification rate of the product has been greatly improved. It shows that the research on the manual debugging process based on the anti-vibration qualification rate is great significant.
