Abstract

Abstract: Aiming at the limitation of load testing technology， this paper proposes an analytical method for the dynamic analysis of engineering structure using the acceleration information. The test acceleration is used as input excitation of the battery frame assembly model， then the simulation analysis of dynamic characteristic is used to calculate the strength distribution and dynamic response of the battery frame assembly model of heavy tractor. At the same time， the accuracy of the method is verified by comparing with the test results of actual roads. Research results show that the proposed method can be used to solve the dynamic characteristics of engineering structures accurately and effectively， and the method has important engineering application value for enterprises in shortening the research and development period of products.

Key words: acceleration response, dynamics characteristic, tractor, base motion, simulation analysis
