The Study On Mechanics Analyze And The Design Of The Main Structure Of The Dropping Top Coal Hydraulic Powered Support

For the reason of the manufacture of high dependability dropping top coal hydraulic powered support is one key of whether the high yield and high efficiency-which is the collieries pursue today-can achieve, systematic study is necessary for top coal reverse four connecting-rods hydraulic powered support. Starting from the design point of view, elaborate the design technology of top coal reverse four connecting-rods hydraulic powered support, then according to VB, compile the system of movement of hydraulic powered support and force analysis, and analyze the structural intensity of the main stressed part of hydraulic powered support by the finite element method, point out the feature of the stress on the hydraulic powered support . At last, optimize the box body on the top beam of the hydraulic powered support using the optimizing design in matlab and ansys, provide the foundation of scientific and reasonable design for the hydraulic powered support.
