【Abstract】 This paper describes briefly the basic theory of the model analysis with ha-mmering method, and the testing technique for measuring the transfer func-tions between tyre and handle of walking tractor.Some modal parameters were directly identified from the measured data of these transfer functions. The results show that the hammering method is an easy and feasible approach for measuring dynamical characteristic of some parts of a tractor.更多还原
