Roller mechanism on SH37D tobacco dryer was the key equipment of roller mechanism of tobacco dryer, aiming at the SH37D roller support connection had fracture phenomenon during the working condition, carry on tobacco dryer roller mechanism based on ADAMS. Use Solidworks and ADAMS software, set suitable virtual work environment, carry out dynamic simulation for tobacco dryer mechanism, acquire tension curve of support connector, use material mechanics technology to carry out mechanical analysis for support connector, get reason for connector damage, and improve connector structure. The simulation results show that the analysis can support connector part mechanical calculation and strength check with theory, and it had great engineering value.
