-rocker planetary gear train was discussed, and the mathematical model of the seedling pick-up mechanism was established. The static trajectory of seedling pick-up mechanism was analyzed and optimized through MATLAB programming, four main parameters influencing the trajectory characteristics of seedling pick-up arms were optimized by choosing different numbers, and a series of optimal structural......
Semi-solid microstructure and its evolution of LC9 aluminum alloys prepared with directly heating-isothermal treatment methodWANG Wei-wei(王卫卫)1, SONG Jian-li(宋建丽)2, HAN Fei(韩 飞)1(1. Department...:directly heating-isothermal treatment; aluminum alloys; semi-solid; microstructure evolution......
of the mechanism was compared with that of non-redundant mechanism. The results show that the performance of the mechanism is improved by adding redundant actuators. Taking circular curve as a trajectory, the simulation of the circular trajectory motion process of this mechanism is carried out. The simulation results verify the feasibility of this design and show the ability of the mechanism to realize......
