The invention discloses a method for solving rigidity of a plate spring by using an automatic dynamic analysis of
mechanical system (ADAMS). The method comprises the following steps of: step one, determining
basic dimension parameters of the plate spring according to a design paper of the plate spring; step two, establishing a three-dimensional model by employing CATIA
software to perform reasonable segmentation, and selecting necessary coordinate points; step three, establishing a Point hard-point, a Box block and a Beam beam in an ADAMS / View, putting forward an equivalent middle surface method in attribute setting of the Beam beam, and establishing
contact force Contact; and step four, setting a
simulation analysis environment of a stress-deformation curve of the plate spring, and employing a method for loading loads through contact of a flat plate and a
spheroid to obtain a
simulation curve. The method solves the problems in establishing a plate spring flexible body model through the ADAMS
software, and the problems in performing
simulation setting on the stress-deformation curve of the plate spring flexible body model, and has important meanings for improving the modeling, analyzing and solving accuracies and the calculation speed of mechanical
simulation software.
