Hydraulic test control system with LabVIEW

The steering system ensures that the vehicle is steered smoothly and in the desired direction. When the vehicle is to be turned, the parts between the steering wheel and the wheel are subjected to stress under certain loads. Steering parts used in suspension and steering systems are parts that work by pushing the limits of mobility. Thanks to the steering system, this movement is converted to the wheel cutoff angle at the rudder. The steering system must be durable, responsive and sensitive about the vehicle's various parameters and to communicate changes in these parameters to the driver as much as possible. It is necessary to determine the torque and clearance values of the articulated parts on the vehicle by subjecting them to the wear and fatigue test, and to idealize the life with the optimum part geometry and material selection by referring to the original parts. However, these parts operating in the bearing environment are faced with wear problems caused by friction. Fatigue damage is frequently encountered due to the fact that articulated parts are exposed to dynamic stresses in the service environment beyond wear. Both the wear and fatigue service environment and the presence of multiple components in the system make technical analysis of the system nearly impossible. However, the performance of ball joint suspension and steering systems needs to be tested, including wear fatigue tests. In this study, it is aimed to develop a hydraulic dynamic test system by using the graphical programming language LabVIEW for fatigue testing of the parts used in the steering system. The data collected from the sensors used in the test system were transferred to the computer environment and the results obtained were compared with the data obtained from the original parts. After the fatigue test, the wear, torque and clearance values of the suspension parts between the steering wheel and the wheel and the operating conditions on the vehicle were successfully simulated.
