Abstract

The invention provides a vertical force-bearing bench testing method for a plate spring. The vertical force-bearing bench testing method comprises a rigidity characteristic test, a dynamic rigidity characteristic test and a vertical-direction fatigue test. The testing method of the invention realizes sufficient simulation of vertical force bearing and motion of a plate spring assembly on a vehicle so that performance of the plate spring assembly sufficiently satisfies a requirement for whole-vehicle motion. In the rigidity characteristic test, the dynamic rigidity characteristic test and the vertical-direction fatigue test, scientific performance and high accuracy are realized; and furthermore through a vertical force-bearing bench structure for the plate spring, influence of a torque which is generated after inclination of the plate spring assembly to the bench is prevented, and high safety in the testing process is ensured.

Description

technical field [0001] The invention belongs to the technical field of leaf spring detection, in particular to a test method of a leaf spring upper and lower force bench. Background technique [0002] Leaf springs (referred to as leaf springs) can be placed vertically or horizontally on the car. Because the horizontal leaf spring needs to transmit the longitudinal force, an additional guiding force transmission device must be provided, which makes the structure complicated and the mass increased, so it is only used in a small number of light and miniature vehicles. Longitudinal leaf springs can transmit various forces and moments, have a guiding function, and have a simple structure, so they are widely used in automobiles. [0003] Longitudinal leaf springs are divided into symmetrical and asymmetrical. If the distance between the fixed center of the middle part of the leaf spring on the axle (bridge) (here the bolt is called the center bolt) and the center of the ears at ...
