Abstract：

The portable stiffness testing instrument for automotive panel was developed,and the defects,such as heavy inconvenience and non-standard in the process of stiffness measure were avoided.In order to complete the normal load test,the testing instrument could be performed on the arbitrary point of three-dimensional space of curved surface by adjusting the stiffness testing instrument,and the accuracy and normatively of evaluation on automotive panel stiffness was achieved.The portable stiffness testing instrument can be widely used in the production of automotive panel at the scene,and it plays an important role on guiding the production.
