Modeling of the Stress-Strain State of Load-Bearing Structures in Abaqus and MeshFree Software Systems at the Stage of Design of Aviation Equipment Products

The results of the study of stress-strain state of the “shock-absorbing strut” part, which is a load-bearing element of the aircraft landing gear structure, are presented. A monolithic rod structure exposed with complex loading was considered as a mathematical model. Approaches in the study of the stress state of the structure by the finite element method and the finite point method are proposed. Numerical algorithms of approximate solution of differential equations of elasticity theory are implemented in software packages Abaqus and Midas MeshFree for modeling the stress-strain state of a shock-absorbing strut. Comparative analysis and accuracy assessment of the obtained results are given.
