Motion and Static Simulation of Rowing Machine

Abstract

In this paper, a rowing machine is designed according to rowing action. Then, on the one hand, motion simulation is finished by using SolidWorks to obtain its displacement and velocity, and verify the size of each rod of the rowing machine. On the other hand, static simulation is finished by using SolidWorks to obtain its stress during one cycle and then optimize the diameter of the handrail for ensuring the comfort and safety. The results show that the motion simulation curve is basically consistent with the motion analytical curve of the rowing machine, it verifies rationality of the optimal parameters. The rowing machine can drive the coordinated movement of the upper limbs, lower limbs, waist and abdomen, and back joints of the human body, which is consistent with the traditional rowing movement. It achieves the purpose of training and fitness. Moreover, the speed of the pedal and tailstock remain basically unchanged and no sharp acceleration or deceleration exist, so the rowing machine meets the uniform speed requirements of traditional rowing action and the comfort of use.The maximum stress of the rowing machine appears on the rod L1. It is less than the yield stress of stainless steel AISI-304.
