Research on the Performance of Piston One-piece Two-stage Compressors for Suspensions
In order to understand the working performance of the piston one-piece two-stage reciprocating air compressor for air suspensions,and to provide a basis for the design,optimisation and physical prototype experiment of the new model,the compressor kinematics mathematical model was establshed according to the overall size,and the modelling and simulation was carried out for the air compressor system filling process based on AMESim.The pressure change characteristics of one or two cylinder filling process of the new type of air compressor was got through simulation and compared with the traditional single-stage compressor type.The simualtion results show that the new two-stage piston one-piece air compressor in higher filling pressure can maintain higher filling efficiency.In the setting of 17 bar working conditions,the peak values of the gas force on the piston and the resisting moment are 56％and 47％of those of the traditional model,and the curve changes more gently,which indicates that the use of the new two-stage compressor model can effectively improve the volume coefficient,reduce the load fluctuations,and improve the stability of compressor operation.Physical prototype tests were carried out on the two models,and the test results show that the new model takes 27.3 s less time to ramp up than the traditional model under the condition that the storage tank is 3.7 L and the pressure is charged from atmospheric pressure to 17 bar.The new model's filling performance is better than that of the traditional model,and the simulation charging law is in line with the test results in the high-pressure section.
