By using finite-element analysis software-Ansys, finite-element static analysis and modal analysis are conducted on the main frame of track-laying vehicles in this article. And the stress, strain and dynamic characteristic of all parts of the main frame under operating condition are calculated too. Meanwhile, the maxi- mum stress and strain at carling joint connecting hydraulic motor installation rack and frame are obtained. Besides, the optimum proposal based on the actual situation is presented, thus laying a solid foundation for manufacturing the experimental prototype.
