Comparison of methods of finite displacements calculation under static bending of flat and leaf springs
It is determined that linearization of displacement equation of a bent beam makes a significant relative error in the definition of displacements for flat metal and leaf springs. It is found that modeling of behavior of flat springs and beams using the ANSYS ED 10 must be carried out with the use of BEAM188 and SHELL18 1elements and with the enabled LargeDisplacementStatic option. It is because of non-linearized equation used for determination of displacements that corresponds to large deflections and displacements of elastic line.
