Finite Element Analysis and Optimum Design of Mining High-strength Flat Type Chain Connector Based on ANSYS

摘要

To enhance and improve structure strength and working life of the existing ladder-type chain connector tooth, the fragile part of chain connector during actual production work is found. The constitutive equation of the three-dimensional elastic body of the chain connector is founded. The contact non-linear module of ANSYS finite element software is utilized to simulate stress distribution of chain connector under the condition of fatigue. And the internal development tool- the Parametric Design Language APDL is utilized to carry out the optimization design, MSC / Fatigue life-cycle method is further utilized to calculate the fatigue life of connectors' structures before and after optimization. Finite element simulation results show that the main part of stress concentration is in teeth roots; optimization design results show that three teeth stress distributions of optimized structure tends to uniform after compared the teeth structure stress distributions between pre- optimization and after- optimization; ca lculation results of fatigue life show that the fatigue life of optimized teeth structure is more uniform. Proved that the optimized structure is more reasonable and provided a theoretical basis for structural improvements.
