The method of vibrating tests which obtain the transfer function of a component in order to analysis the mode of the side drive rotary tilling devices by using the building block method, were investigated. The method of three points supporting for vibrating tests was proposed as a new vibrating test to make the transfer function more accurate, because of the component can not be perfect free state. The proposed method was recognized clearly by the model of spring-lumped mass system and the finite element method of steel plate, and discussed the valuation of error based on reliability for results.
As a results, the transfer function of component was able to be obtained in a higher accuracy and a closer free state. Therefore, it was considered that this proposed method can be applied to the modal analysis for the side drive type rotary tilling devices.
