Based on this,damaged gear modelswith abrasion,pitting and crack were developed respectively and the meshing temperature field was compared with that of the intact one. The results show that the meshing temperature field of gear tooth can be given accurately using high precision infraredradiationthermocamera. Thetemperature inspection couldbeoneof thenovel methodsfor thenonde鄄 structive inspection of the rack and pinion ofjack鄄up platforms. Key words:finite element analysis;jack鄄up platform;rack and p
