[0005] In fact, during the torsion process of the leaf spring, the torque is mainly borne by the first leaf and the second leaf. When the leaf spring bears the Y-direction force, the first leaf spring bears most of the force. When calculating the properties, each The influence factors of the leaf on the force are different, and the direct superposition of the properties of all leaf springs may lead

Abstract

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.

Description

technical field [0001] The invention relates to the research field of leaf spring stiffness simulation calculation, in particular to an analysis method for establishing a leaf spring model and simulating stiffness curve by using the mechanical simulation analysis software ADAMS. Background technique [0002] Leaf spring is the most widely used elastic element in automobile suspension. Its function is to connect the frame and axle together in the form of suspension, bear the load impact of the wheel on the frame, reduce the severe vibration of the body, and keep the vehicle Driving stability and adaptability to different road conditions. Stiffness is an important physical parameter of leaf spring, which directly affects the performance of vehicle suspension and vehicle. [0003] With the development of modern theory and the improvement of calculation level, the traditional concentrated load method and common curvature method are replaced by modern computer software simulatio...
