【Abstract】 The main excitations and characteristics of the vibration transmitted by handles of GN5 walking tractor were studied by means of theoretically analysis and test.The vibration of handles were evaluated in reference to ISO 5349-1986(E).It was concluded that the main excitation of vibration was engine,and the vibration on the handles of GN-5 walking tractor was very strong and affects the health of drivers seriously. These results furnish theoretical basis for designing the absorber of vibration transmitted by handles of walking tractor.更多还原
