| A flexible screw drive mechanism named as FDM is an engaging novel drive structure which is composed by a flexible shaft and a nut body inserted with several rollers each installed with two bearings. FDM resembles ball screw and but also supports curved path transmission with high efficiency and stability, which has broad application prospects. In this paper, the dynamic and kinematic experimental platform is established, which helps make relevant experiments on the flexible drive mechanism's driving performance under different working conditions.In this paper, according to the comparison of traditional flexible drive mechanisms and related experimental research methods, the overall design of driving performance test platform on FDM is proposed, and its overall frame, hardware structure and software function are designed.Many driving performance tests on the soft drive mechanism is performed using the experimental platform, including tests of the driving force, driving stroke, driving stability, slipping rate of rollers and the driving efficiency. It compares different effects of driving speed, size and direction of load, drive path on the transmission performance of FDM and displays in charts. Experimental results show that the soft screw drive mechanism has an excellent transmission performance and can be optimized to meet different transmission requirements by reasonably designing the structural and transmission parameters.The research of this paper provides some experimental basis and theoretical value for the practical engineering application of the FDM. |
