Dynamics Simulation Analysis of Artillery Traversing Mechanism Contact with Clearance

The artillery traversing mechanism with clearance contact rigidity coefficient is simulated applying finity element method and validated by ceasing firing dynamic simulation and experimentation aiming at the calcuating problem of contact model of artiUery firing dynamic simulation. Firstly, the artillery traversing mechanism export gear and barbette circle gear single degrees-of-freedom model is built up and the contact formula is defined, then the contact pressure, penetrate and friction with a certain original load are calculated applying finity element method and the contact coefficient is dispelled based on the contact force formula Lastly, the dynamic contact response of firing process is simulated applying ADAMS software and the simulation model is validated based on the ball firing dynamic parameter experimentation. The result can afford guidance for artillery traversing mechanism structure design and check and afford theory accordingfor firing precision analysis.
