Design of the Stand for Experimental Tests of Pneumatic Bellows Actuators
摘要
The article contains an analysis of the possibility of precise position control of a bellows actuator. For this purpose, a special research stand was built. It allows an accurate determination of the static and dynamic characteristics of air springs under variable loads generated by a pneumatic cylinder. The bellows is placed on a prototype base, enabling, apart from precise height measurement, determination of changes in the volume of the bellows immersed in liquid. Based on the experimental data, a formula for the effective area of the bellows was derived, depending on its height and the applied load. Subsequently, a mathematical model of the stand was made which was used to carry out further simulation tests in the MATLAB /SIMULINK environment.
