RANDOM VIBRATION IMPACT ON TWIN-TUBE HYDRAULIC SHOCK ABSORBER FUNCTIONING FEATURES IN A TWO-STAGE SYSTEM. PART TWO: AN ANALYSIS OF A TWIN-TUBE SHOCK ABSORBER IN A CRITICAL STAGE FUNCTIONING
The paper describes the mathematical model for a kind of twin-tube hydraulic shock absorber. A description of a passive shock absorber and the analytical complexities of the oil flow are discissed. The oil compressibility and the entrapped gas in the oil are considered in the model. It is found that the problem-of-water fraction is increasing while the decreasing of the velocity system.
