Polohování dynamometru otevřeného zkušebního stavu

Abstract

The Juliska Laboratories of Czech Technical University contain testing equipment for both in-house as well as commercial collaborative researches undertaken by the Automotive Department. One such apparatus is the Open-Loop test stand. The open-loop test stand has a set of dynamometers installed on it for various testing purposes. The dynamometers are required to be moved linearly on their rails as per the test requirements. For this, the present work proposes a new system that accommodates the proper positioning of one of these two dynamometers within the rails. The proposal includes choosing of physical parts, including but not limited to sensors, valves, actuators and an electric motor. The physical parts make up the pneumatic and electric sub-systems also a part of the proposed work. The physical parts include the stepper motor and its controller, draw wire sensor, limit switch, solenoid valve, electromechanical relay. All the necessary changes required to be made to the test stand are also incorporated into the proposal. These include the mountings for the gearbox and stepper, mounting for the draw-wire sensor installation. Lastly, the present work also proposes a virtual setup of the above-mentioned physical parts in the LabView environment, providing an alternative means of control. This includes one program through which all physical parts, that are a part of the system can be controlled/monitored. Hence, giving the user choices of both manual as well as automated ways of operation.The Juliska Laboratories of Czech Technical University contain testing equipment for both in-house as well as commercial collaborative researches undertaken by the Automotive Department.
