Article Title Numerical and Experimental Research on Pitch Mechanism of Gun with Clearances
Keywords Clearance, Gun, Dynamic, Firing Concentration.
Abstract The clearances in pitch mechanism of gun have an important influence on firing concentration. The present study designs a set-up of experimental research on pitch mechanism of gun with clearances and carries out corresponding numerical simulations and experiments. The clearance in slider-guide joint, a typical clearance in pitch mechanism of gun, is considered in the set-up. Sinusoidal excitation is used to get dynamical response signals of gun; results of the experiments show that the response signals in time domain reflect clearance size. In the same intensity under sinusoidal excitation, the peak value of gun barrel’s time-domain signal is larger with the clearance enlargement. The current work can be referred as a basis for dynamical clearance adjustment and the gun design.
