Bearing-Load Modeling and Analysis Study for Mechanically Connected Structures

By: Nasa, National Aeronautics and Space Adm

Bearing-load response for a pin-loaded hole is studied within the context of two-dimensional finite element analyses. Pin-loaded-hole configurations are representative of mechanically connected structures, such as a stiffener fastened to a rib of an isogrid panel, that are idealized as part of a larger structural component. Within this context, the larger structural component may be idealized as a two-dimensional shell finite element model to identify load paths and high stress regions. Finite element modeling and analysis aspects of a pin-loaded hole are considered in the present paper including the use of linear and nonlinear springs to simulate the pin-bearing contact condition. Simulating pin-connected structures within a two-dimensional finite element analysis model using nonlinear spring or gap elements provides an effective way for accurate prediction of the local effective stress state and peak forces.Knight, Norman F., Jr.Langley Research CenterMATHEMATICAL MODELS; BEARINGS; MECHANICAL PROPERTIES; HOLES (MECHANICS); JOINTS (JUNCTIONS); AXIAL LOADS; NONLINEARITY; TWO DIMENSIONAL MODELS; FINITE ELEMENT METHOD; PINS; SIMULATION; STRESS DISTRIBUTION; RIBS (SUPPORTS); PANELS
