Analysis on Efficiency or Advantage of Lifting Mechanism for Loader 921747

In the recent years, the design on the link-mechanism of working device in a loader is gradually being prefected, but the design on the link-mechanism of boom-cylinder is seam to be still at the cut and try level. In order to further improve the design method of boom cylinder, in this paper, using a concept of “dfficiency” or “advantage” and a method combining the theoritical analysis with the computer computation, we make an attempt at analyzing and discussing this problem. And finally we obtain some conclusions for increasing the design quality of the link-mechanism.
