Analysis and Experimental Determination of Cable-Driven Stiffness
Abstract— The current reach of transmission mainly focuses on the gear drive. Compared with the typical gear transmission, cable drive has been widely used in many fields because of its advantages of large transmission torque, simple structure, smooth transmission, being easy to install and maintain. The accuracy of cable-driven stiffness calculation is increasingly required. Aiming at the problems of the calculation of equivalent stiffness lacked the analysis of preload mode and wrapped angle, a cable-driven preloaded device is designed in this paper. By analyzing the distribution of cable tension in different preload modes, the variation of slip region of tight side and slack side after loading is deduced. The equivalent stiffness equation of cable drive is obtained. The influence of design parameters on the stiffness of cable drive is analyzed. Experimental equipment was designed to measure parameters related to cable stiffness under different design parameters. The correctness of the theoretical analysis was verified experimentally. These results can provide reference for engineering design.
