Stress Distribution Behavior of Spherical Plain Bearing Fabricated by TiAl-Based Composite Materials Based on the Finite Element Analysis

Article Preview

Abstract:

Spherical plain bearing is a sliding bearing have a spherical contact surface,it can bear larger load and automatically adjusted to the self-alignin. TiAl-based composite material is a material that be used to lightweight spherical plain bearing. The Simulation used the finite element software Ansys for the bearing’s static analysis.The material of outer ring using normal bearing steel, one group used the TiAl-based composite materials as the material of the inner ring, Another group the inner ring material is bearing steel 9Cr18. The law of the stress and strain produced by the two groups is consistent,the deformation of the composite materials is bigger under the same load, its elasticity modulus and density is smaller compared to the ordinary bearing steel,the composite material has the advantages of high specific strength especially in the occasions have strict requirements of the bearing weight.
