Abstract:In order to meet the requirements of aircraft tire temperature automatic measurement immediately after wheel brake or tire roll test,developed a set of tire temperature automatic measuring measurement device which installed in aviation inertia dynamometer with limited local space. Pneumatic system, electrical system, control system and acquisition system were used to drive the probe for the tire crown, tire shoulder, tire side wall measurement temperature automatically. Swing frame structure was used to amplify the motion track of the motion mechanism, then the cylinder with a stroke of 350 mm could be used for the wheel with a diameter range of 380~1 500 mm,additionally designed the angle adjustment mechanism, probe box, roller mechanism, locking mechanism, which could implement function in angle adjustment, plant protection, signal feedback and transfer wheel, and etc. In the pneumatic system, sequence of the action and action safety interlock circuit are designed to realize the mechanism order action and equipment safety protection to improve the test efficiency and to avoid the risk of test.
