ABSTRACT
This dissertation mainly to an open coalmine ground production system, one broken to stand steel construction finite element analysis. Store -give material machine and broken platform- control room two parts make up the crush station. Finite element analysis to the steel construction of two parts comparatively. Find the dangerous part to carry on concrete analysis of the result.
First of all, set up the finite element of Store -give material machine’s entity model. Calculate the equivalent load; solve out the stress and strain of the steel construction under the load and analysis their distribution situation.
The next place, the course of solving is the same as above. But the connections of the broken platform and control room are the hinged joint, so deal with by coupling in the course of modeling.
Finally, carry on mode analysis to two finite element entity models; it is solve the intrinsic frequencies and mode picture of shaking, respectively.
