The Design of Four-Bar Linkage of Large Inclined Angle Hydraulic Support

摘要

Four-bar linkage is one of the most important components of shield-type powered support or chock-shield-type hydraulic support. Parameterized modeling, simulation and optimization of four-bar linkage is firstly accomplished by use of ADAMS software in designing a large inclined angle hydraulic support. Then based on three-dimension model of the whole hydraulic support, applying COSMOS/Works software, finite element analysis is made under the front torsion load of roof beam. The analysis result validates the feasibility of four-bar linkage design and meets the design requirements very well. This method can effectively shorten the design cycle and improve design efficiency of hydraulic support.
