Analysis of Crimping Process of Turbo Actuator Based on Multi-target Orthogonal Test

This paper mainly studies the crimping process of turbo actuator at passenger vehicle. Firstly design a series experiments with a method of orthogonal test, then study and analysis the crimping results both by single factor visual analysis and multi-factor orthogonal matrix analysis, finally it concludes the influence tend of the main three process parameters at crimping including surface bevel beta and contour radius R of upper die and stamping pressure P on the main three forming quality indicators including E, F and thickness T of actuator's cross section dimension. Moreover it puts forward an optimal process parameters combination of one actuator's crimping process and verifies the conclusion by sample statistical analysis in continuous trail run production.
