Abstract


Hydraulic support is fully mechanized coal mining face one of the most important equipment is mechanized mining support equipment in the largest investment , the use of the largest number of devices. As technology continues to improve and gradually intensified market competition , the design of hydraulic support required to improve the performance of the work under the premise to ensure as much as possible to reduce weight and improve economic efficiency. Based on a hydraulic support for the study, using Pro / E software to establish a hydraulic support machine model and interference checking was carried out , and then through the middle IGES files will cover the three-dimensional solid model of the beam into ANSYS software , completed its structural finite element analysis . In finite element analysis , based on the establishment of a shield beam optimization model , using ANSYS software to complete its structural optimization . First through the Pro / E software to establish a three-dimensional modeling of hydraulic support each component model , make full use of the machine after assembly interference checking to check the reasonableness of modeling . Three-dimensional solid model allows designers intuitive understanding of their key components of hydraulic support structures and assembly relationships , shorten the design cycle and improve design efficiency. Then through the IGES file will cover the intermediate beam model into ANSYS finite element analysis software, the model meshing properly , according to the load imposed constraints and load analysis results , the establishment of screening beam finite element analysis model through in ANSYS analysis and calculation , the beam spots obtained cloud stress and strain , the resulting data consistent with the actual situation . Finally shield beam finite element analysis , based on the established shield beam structural optimization design model , using ANSYS as an optimization designer , using its parametric design language APDL, the use of zero-order optimization method, effectively completed the screening beam structure optimize the design. Meet the iterative precision , based on the optimization results satisfactory , the optimized design of the original design to reduce the weight compared to 6.53% , the effect is obvious optimization . This topic is of key components of hydraulic support is designed to provide a set of precise , reliable and fast modern design methods .
