This study presents stress analysis of sheave wheel by a finite element analysis model and experimental tests. Simulation of stress field under two kinds of load condition was carried out with ANSYS. The corresponding relationship between stress and load of hoist as well as sheave wheel´s phase angle were obtained. Then field experiments of sheave wheel stress under three kinds of conditions, which were no-load, heavy-load and rope-slack, was conducted using the wireless stress monitoring system and the experimental data were analyzed and compared with simulation results. It is found that the spoke of sheave wheel is the ideal position for stress measurement. Moreover, the spoke´s stress increases linearly with the hoist load and changes periodically as sheave wheel rotates. Consequently, it is verified that the hoist parameters such as load, displacement and velocity can be monitored real-timely by calculation of the detected stress changes of sheave wheel, which proves the validity and feasibility of this novel monitoring method of hoist.
