【Abstract】 The parameters correction method of dynamic design model in construction machinery presented in this paper has been successfully used in the design of shovel loader model ZL40. This method is based on the finite element dynamic analysis and model testing. Through the creation of dynamic sensitivity analysis program, the sensitivity of inherent frequency versus various structural parameters is obtained and dynamic design model parameters are effectivily corrected.更多还原
