Optimum Design of LHD Working Device Based on Virtual Prototype

The designs of LHD in China depend on the experience in general,so there is great limitation.This paper introduced the virtual prototyping technology.First the preliminary design of the working mechanism of certain LHD is finished with analytic method,then the three dimension modeling is constructed and transmited to RecurDyn for kinematic analysis.It is found that this mechanism can not meet the capability of automatically flating down the working mechanism.So the optimization model is constituted and called the toolbox of MATLAB to calculate for optimization.Doing motion analysis with improved model,the result displayed that to the design requirement was fulfilled.
