The Experimental Study on Modal Parameters Identification for Motorman-HP20 Robot

Abstract:

The dynamic characteristics of light-weighted structure are more important due to its flexible property. In this paper, the experiment of modal analysis for Motorman-HP20 robot is carried out. The method of one location for response and multi-locations for excitation are applied in the experiment. The orthogonal polynomials curve fitting method is used for modal parameters identification. The first six order modal parameters are obtained. The results show that the structure of L-shape arm may be re-designed due to the modal shapes due to severe vibration of L-shape arm in modal frequencies of some prior orders and the poor base frequency.
