Experimental Investigation on Single Person’s Jumping Load Model and Its Parameters

Abstract:

This paper aims to develop the load model for single person’s jumping. The three dimension motion capture technology was employed in the experiment in conjunction with force plates to record the jumping load curves. One hundred subjects participated in the experiment and every subject completed five test cases including one free jumping case and four fixed frequency jumping cases. Based on the experimental results and the classical Fourier series function, the jumping load model was developed and its parameters could be determined by the preset jumping frequency or the jumping contact ratio. Maximum order of harmonics of the model was proposed to be as six. Advantages and disadvantages of the two ways were discussed as well as the detailed application procedure of the model.
