Identification of Clearance and Contact Stiffness in a Simplified Barrel-Cradle Structure of Artillery System
In gun barrel-cradle structure, the presence of clearance usually changes the dynamic response of muzzle and results in shooting dispersion (under continuous firing condition).The parameter estimation of such clearance nonlinear system is the prerequisite for establishing quantitative relation between the clearance and muzzle disturbance.In this pa
