METHOD AND INSTALLATION FOR VERIFICATION ON RIG, THE EFFICIENCY OF TRIM CORRECTOR EQUIPMENT, ACHIEVED WITH ORIGINAL ROMANIAN TRIM ACTUATORS

Abstract

The paper show the method and installation conceived to adjust and verify on rig, the efficiency of trim corrector equipment, made with the original Romanian shock absorbers with cylindrical pneumatic trim actuators - patent application PCT/EP2016/061515, belonging to the first author. The trim actuators are controlled with electro-pneumatic equipment realized according to a solution from the nominated patent application. For simplicity, the installation uses a traction-compression machine between whose ferries is fitted the shock absorber equipped with the pneumatic actuator, it being linked to the three-way valve that realize the connection with air compressor or with atmosphere, function to the wanted floating force. The method is to verify the actuator capacity to realize wanted buoyant force at different elongation, thus assuring possibility to put the vehicle in wanted body ground clearance, for any vehicle load state.
