Abstract

Symmetrical rubber buffers mounted on a tracktype bulldozer are used in passive damping for the reduction of vibrations. As heat accumulation due to hysteresis  may occur in continuous operation distributions of three typical cases were  evaluated by FEM. The simulation result shows that hysteresis–related heat  accumulation occurring near the contact region of the rubber pad remains unchanged in different cases. The maximum temperature in the case of  earthmoving somewhat exceeds the range. The value of cutting and bulldozing is below the range. The value of loosening obviously exceeds the range. The great conductivity gap of heat flux between steel and rubber, which caused the most  heat, was dissipated through the steel plate. Superficial temperatures were  measured with a non-contact thermometer for the convenience of calculation that revealed a fair agreement between simulation and measurement in the case of  earthmoving and cutting andbulldozing case. A lot of hysteresis-related heat  produced due to excessive load caused a large error.
