Abstract

The principle of the pneumatic servo that composed of pressure reducing valve，solenoid valve，single- flapper valve，single acting cylinder was analyzed，and its mathematical modeling was also built． The influence fac- tors of pneumatic servo-mechanism were analyzed based on the different altitude． The results show that the air sup- ply temperature，ambient temperature and air supply pressure have small influence on the characteristics of the ser- vo-mechanism． When altitude rises，the back pressure of the pneumatic system decreases，resulting in a significant change in the working point of the servo-mechanism．

Key words： pneumatic servo; numerical simulation; mechanism characteristics; influence factors
