Abstract

The invention discloses a method for predicting a service life of a rubber shock absorber; the method comprises the steps: combining aging factors, influencing the use of the rubber shock absorber, and fatigue factors; firstly, establishing an aging service life prediction mathematic model of the rubber shock absorber in use of a hot air accelerated aging test; secondly, establishing a model relationship between static rigidity of a new absorber and fatigue times by means of the aging service life prediction model and the existing performance parameter of an old absorber; further, establishing a relation model between the static rigidity and the time and obtaining a service life prediction model of the rubber shock absorber, thereby realizing prediction of the service life of the rubber shock absorber. The aging factors and the fatigue factors are combined well to predict the service life of the rubber shock absorber, and the prediction precision is high.

Description

technical field [0001] The invention relates to the technical field of life prediction of rubber shock absorbers, in particular to a prediction model of service life of rubber shock absorbers used for vibration reduction and noise reduction. Background technique [0002] Rubber shock absorbers have adjustable elastic parameters, can attenuate and absorb low-frequency, high-frequency vibration and noise, impact stiffness is greater than dynamic stiffness and static stiffness, and have the advantages of small size, light weight, and maintenance-free, so they are widely used in various fields. use. However, due to the fatigue damage of stress and strain and the aging of rubber materials in the actual use of rubber shock absorbers, there is a problem of service life. Once fatigue damage and aging of the rubber material occurs, the stiffness and damping parameters of the rubber shock absorber will gradually deviate from the design value, and its vibration isolation and impact re...
