Abstract:

Hybrid-driven mechanism is one kind of controllable mechanism. The characteristics and advantages of moderate flexibility and reducing the cost of driving and controlling of hybrid-driven mechanism make it become one of the important branches of modern mechanisms. The theory and application of hybrid-driven mechanism are constantly developing and innovating along with the further research of hybrid driving mechanism. Analyzing and summarizing the existing research results will be beneficial to promote the further development of the theory and application of hybrid-driven mechanism. The connotation of hybrid-driven mechanism is analyzed. The research progress of two-DOF and multi-DOF hybrid-driven mechanism is discussed, respectively. The main contents are follows type synthesis and mobility of hybrid-driven mechanism, trajectory characteristics of hybrid-driven mechanism, kinematics and dynamics of hybrid-driven mechanism, applications of hybrid-driven mechanism, etc. The key issues of in the research of hybrid-driven mechanism are presented. The future development trend of hybrid-driven mechanism is summarized. The results have important significance to expand the design space of hybrid-driven mechanism, and to open up new application fields of hybrid-driven mechanism.

Key words: controllable mechanism, development trend, research progress, hybrid-driven mechanism
