Abstract

The invention relates to a plate spring strength analysis method and system, a readable storage medium and computer equipment. The plate spring strength analysis method comprises the steps that: a preset plate spring model is obtained, griding processing is conducted on the plate spring model, and if the number of plate spring pieces is larger than 1, self-contact setting is conducted on the plate spring pieces; constraint processing is performed on the plate spring model; according to a vehicle durability road test, six wheel center components are collected and loaded into the whole vehicle multi-body dynamic model, a load spectrum of the plate spring model is obtained, multiple working conditions are preset, the load spectrum is analyzed and processed, and the strength load of the plate spring seat is obtained; and the obtained strength load is input into a finite element model for checking. According to the invention, the problem that the stress condition of the plate spring cannot be comprehensively analyzed in the traditional plate spring strength analysis process is solved, so that the stress analysis of the plate spring is more accurate.

Description

technical field [0001] The present application relates to the technical field of leaf spring simulation, in particular to a leaf spring strength analysis method, system, readable storage medium and computer equipment. Background technique [0002] Automobile leaf springs are simple in structure, low in cost, and easy to maintain, and are widely used in passenger cars, trucks, and pickups. [0003] The strength calculation of the traditional leaf spring design is based on the classic material mechanics beam bending theory. This method only solves the leaf spring strength problem caused by the vertical load FZ (vertical load of the leaf spring) or DZ (vertical displacement of the leaf spring). The strength problem caused by the leaf spring is not considered by loads in other directions. [0004] However, since the new energy vehicle is installed on the rear axle due to the electric drive device, the load FX (X axial load), FY (Y direction load), MX (X direction torque), MY ( ...
