    Abstract
  • For the auto-body panel parts characteristics, a test method of dent resistance was introduced. Based on the test method, an automatic tester system for dent resistance test was developed. The tester indenter can be adjustable with arbitrary posture in space and load reliably by integrating "5-axis motion + 1-axis loading". Control hardware system with "PC + motion controller" structure was constructed based on programmable multi-axis motion controller(PMAC). The corresponding control software was developed. Six-axis tester was controlled accurately. The normal vector of a test point on parts was obtained with one approximation method. The motion data of tester indenter adjustment from initial position to test point normal direction was calculated based on the principles of robot kinematics, so the tester was able to load automatically in normal direction of test point on panel parts. Calibration and application indicate that the testing system works stably and reliably.
