This paper presents the results of tests conducted on a pneumatic system using medium and high pressure actuators. These tests aimed to:-detect the behaviour in dynamic regime of the drive system with medium pressure pneumatic actuators, pneumatic spring type load, achieved by installing throttles on the piston and rod chambers of the pneumatic drive actuator, respectively controlled using the pressure regulator valve, for step, ramp and sine wave signal (plotting the BODE diagrams: attenuation vs. frequency and phase vs. frequency);-identify the methods and ways for optimization of dynamic and energy performance of drive systems with medium pressure pneumatic linear actuators.
