In this paper, the basic principle of modal analysis by hammering method and the experimental technique of measuring the transfer function of walking tractor by hammering method are briefly described. Some modal parameters are directly identified from the measured transfer function data. The result It shows that the hammering method is a simple and feasible method to measure the dynamic characteristics of some tractors.
