LOAD CONTROL POSSIBILITIES OF EXPERIMENTAL LINEAR DRIVE

Abstract

The article describes a load drive extension for an existing laboratory experimental equipment for testing of linear drives with ball screw. The main aim is to simulate the static component of the load, and therefore the pneumatic actuator has been selected. The control elements (electro-pneumatic valves) and appropriate control strategies are also investigated. The experiment was performed with two valves exactly on the extended device and comprised of examining the behavior of the monitored system and basic capabilities of pressure-force regulation. The experiment set-up directly corresponds with the proposed use of this extension. The achieved results illustrate the ability of the load system to simulate primary the static forces. Finally, the adaptation and development are presented to improve not only the dynamic abilities of the loading system.
