Abstract

The invention provides an up-down stress bench test method for a plate spring. The bench test method comprises a stiffness characteristic test, a dynamic stiffness characteristic test and an up-down fatigue test. According to the test method provided by the invention, the up-down stress and the movement of a plate spring assembly on a vehicle are fully simulated, so that the performance of the plate spring assembly can fully meet the needs of the movement of the whole vehicle. The test method, including the stiffness characteristic test, the dynamic stiffness characteristic test and the up-down stress fatigue test, is scientific and precise, and the influence of torque generated by the tilting of the plate spring assembly on a bench is eliminated by the up-down stress bench structure of the plate spring, thereby ensuring the safety of the test process.

Description

[0001] This case is a divisional application [0002] The original application number is: CN201610703550.9 technical field [0003] 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 [0004] 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. [0005] Longitudinal leaf springs are divided into symmetrical and asymmetrical. If the distance between the fixed center of the middle part of...
