The Method of Dynamic Design and Reanalysis on the Structure of Woodworking Machine Tool Based on Sensitivity Analysis

According to the characteristics of woodworking machine tool,this paper treat the order of inherent frequency at which may resonant in the working process as the dynamic optimum target.Then found out the location and parameter which to be revised by calculating the sensitivity of mass,stiffness and damp to the frequency respectively and introduced a kind of reanalysis method to calculate the shake type after revised.The result of dynamic design on the backstop of A503 shows that this method may increase the inherent frequency which be treated as the optimum target,and weaken the swing effectively.
