Abstract—The tension study of accumulator is a critical factor in designing hydraulic system. The accumulator regarded as air spring when connected with cylinder plays the role of shock absorption and energy storage. Based on the luffing mechanism of crane, this paper structures mathematical model of accumulator-cylinder, simulates and analyzes the frequency response characteristics of the accumulator, and verifies the constant tension characteristics in experiments. The results show that the volume of accumulator decides the compensation effect. But no matter how large the volume of accumulator is, complete compensation could not be achieved. The comparison between system pressure and the boom motion shows the superior constant tension characteristic of the accumulator.
