General profiles chosen from worn wheel profiles and railheads (briefly, worn wheel and rail profile) measured by wheel-rail profile admeasuring apparatus were used to build the finite element models, and the new/worn wheel-rail contact problems were analyzed respectively on the tangent and curved track. Variable regulations of contact area’s size,(More)
In this paper, tailor-welded blanks (TWBs) of three dissimilar gages for the automotive body inner side panel were analyzed. The basic mechanical properties were measured through the tensile test. Based on this, a method of “rule of mixtures” for measuring the properties of weld metal in TWBs was introduced. Moreover, the error between the(More)
