Three Dimensions Construction Model and Finite Element Analysis of Hydraulic Support and Relevant Model

Abstract

Hydraulic support is an important equipment of coal mine production. Its design and manufacture level affects the safe production and economic benefits of coal mine directly. This paper took ZT6500/19.5/34 hydraulic support as an example. First, three dimensions solid models of the type simplified hydraulic support prototype and its 1:5 model were constructed by three dimensions construction model software SolidWorks. Then, three dimensions solid models were led in ANSYS software. Finally, the strength test of the type hydraulic support prototype and its 1:5 model were proceeded under base torsion working condition by ANSYS software. The relevant total displacement distribution rule and equivalent stress distribution rule of the type simplified hydraulic support prototype and its 1:5 model were found. The proportion relation of total displacement and equivalent stress between the type simplified hydraulic support prototype and its 1:5 model were confirmed. This provides an effective way of design and research hydraulic support.
