【Abstract】 In view of functional requirements for a Φ2 m size-reduced test stand TBM a propelling system was designed there-for,which includes a mechanical assembly and a hydraulic system.What to follow includes brief description of the test bench in general assembly and the data,how the TBM’S propelling system was designed and how the components were stressed while operating,with details for the hydraulic system,working principles,and critical components so chosen.Finally,simulated analyses were done of stressed components in the mechanical system,and in the hydraulic system with an AMESim initial model.The simulation results showed that such a TBM test bench was reliable and strength of the mechanical assembly in the propelling system was sufficient,so was the hydraulic system in terms of driving force,speed stability,and controllability.更多还原
