Abstract:
In order to solve the problem of high incidence of work-related musculoskeletal disorders (WMSDs) in upper limb lifting workers, a wearable auxiliary device which could be used in upper limb lifting operation was designed. The auxiliary device could be used in upper limb lifting through torsion spring device to reduce the tension of the arm muscles. The back bracket could be adjusted to adapt to the wearers of different height. The 3D model of the auxiliary device was constructed by using SoildWorks software. And the relative position and constraint between the auxiliary device and the digital simulation human were adjusted by using Jack as the main simulation tool. And then the virtual model of upper limb lifting were simulated and analyzed. Through the comparison of Rapid Upper Limb Assessment (RULA) scale, Krist comfort score and simulation results of two-handed reachable domain before and after wearing the auxiliary device, which proved that the wearable auxiliary device could reduce the risk of WMSDs in upper limb lifting workers.
