Embodiment Construction

[0028] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0029] The main solution of the embodiment of the present invention is: applying loads of different sizes on one end of the rod of the piston rod structure to drive the capsule to stretch axially with different amplitudes and frequencies; During the stretching process, collect multiple displacement and force values ​​of the capsule under different amplitudes and frequencies; according to the multiple displacement and force values ​​of the capsule under different amplitudes and frequencies, calculate the displacement change value and force value change value; the stiffness of the air spring bladder is calculated based on the displacement change value and the force value change value. Therefore, through the above solution, the stiffness of the air spring capsule can be calculated only by applying a load at one end...

Abstract

The invention discloses a rigidity measuring method and system for an air spring bag skin and a storage medium, and the method comprises the steps: applying loads of different magnitudes to one end of a pull rod of a piston pull rod structure, driving the bag skin to axially stretch at different amplitudes and frequencies, and carrying out the axial stretching of the bag skin at different amplitudes and frequencies in the axial stretching process of the bag skin at different amplitudes and frequencies, a plurality of displacement and force values of the bag skin under different amplitudes and frequencies are collected, a displacement change value and a force value change value are calculated according to the displacement and force values of the bag skin under different amplitudes and frequencies, and the rigidity of the air spring bag skin is calculated based on the displacement change value and the force value change value. According to the method, few steps are needed, complex operation treatment is not needed, and the rigidity of the air spring bag skin can be simply and rapidly measured.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to a method, system and storage medium for measuring the stiffness of an air spring bladder. Background technique [0002] When the car is driving on a bumpy road, the entire car and its occupants will be subjected to a certain impact force. The air spring can absorb this impact to a certain extent. The appropriate air spring stiffness during the vehicle driving process is conducive to improving driving comfort. and handling stability. [0003] The working stiffness of the air spring includes two parts: the air stiffness and the skin stiffness, and the air stiffness can be calculated by aerothermodynamics and aerodynamics. The existing method for measuring the stiffness of the pure bladder during the working process of the air spring has many steps and complicated operations. If the contribution of the bladder to the stiffness during the working process of the air spring can be c...
