| Abstract: | In this paper, vibration modal characteristics of 1G-180A rotary tiller are studied with ex-perimental modal analysis.The vertical vibration, side vibration and rotary axle vibration ofrotary tiller are analysed by means of experimental data. The upper limit of analysis frequen-cy is 3100H_z. By means of modal shapes and modal frequencies, the side motion stability androtary axle stability of rotary tiller are studied. The problems dealing with the use of modalparameters and frequency response functions in the design of rotary tiller are discusseTheviews that strength reliability and stiffness reliability should be considered integratively inthe design of reducing weight of rotary tiller are advanced, and three kinds of methods to re-alize stiffness compensation of rotary tiller are suggested. |
