| Abstract: | By synthetically analyzing the load that a certain type of aircraft main undercarriage borne under various experimental conditions,a general undercarriage test bench for static and fatigue comprehensive test was developed. The test bench could meet the requirements of structural static and fatigue tests for undercarriage of medium size transport aircraft weighing 100 t. The ceeative designs of device for changing the distance of run of bumper,device for following the points of load and loading crowbar made it possible for doing tests of various versions and heights of undercarriages,which improved the generality of the test bench.The control systems included test loading control system and the loading points following control system. The two systems could be switched freely according to the test process,promoting test efficiency and automation level. |
