Abstract

Hydro-pneumatic transform (short for HP transformer) wastes a lot of compressed air when working, and its power efficiency is low. To improve its efficiency, we carry on the parameter optimization which influences the power efficiency of HP transformer system. Firstly, we build up a mathematical model and use the MATLAB software to simulate. Next, we establish the test bench to experiment and verify the mathematical model. Through simulation we set different values to study the relationship between the efficiency and key parameters. We can get some conclusions that, when the input compressed air pressure ranges from 0.5MPa to 0.55MPa, or the area ratio of piston ranges from 4 to 6, the efficiency will exceed 30%. The efficiency nearly keeps constant when the stroke of the piston varies. What's more, with the increase of input pressure and effective piston area ratio, the output power will be rising. When the piston's stroke increases, the output power decreases a little bit. This paper can be a reference of researches on the design and optimizing of HP power system used on air-powered automobile.
