Then four different design options of the overall structure of the high temperature high-speed owel-on-disc type friction and wear testing machine are given , then a more reasonable option is got after the analysing and comparing of the four options. And the relevant calculations and structural designs of the testing machine's overall mechanical structure are based on this options . The ProE software is used to complete the testing machine’s 3D assembly plans . Finally the 2D assembly of the testing machine and friction disc, friction dowel, and other important components of the assembly are also drawn.Keywords: friction and wear ; testing machine ; mechanical structure ; ProE
