Hemming, especially curl hemming, is required along the wheel housing for safety. Robot roller hemming is suitable for it. In this paper, both the flat hemming and the curl hemming along either the straight profile or the curved profile are analyzed using finite element program MSC.Marc to verify the hemming test results. Both the inner panel and the outer panel are modeled using 3-D solid elements and the roler is modeled using rigid surface. In the curl hemming, there is a case that the curl is not formed if the pre-hemming force is not sufficient. It agrees with the test results.
