Abstract: The design of airplane, when plane is in the flight mode it is because of wings on both sides. While operating at the greater speed the wings are subjected to load which includes whole weight of the aircraft and environmental weather conditions. But also during flying the wings are subjected to much higher loads and stress. This stress should be sustained by the wings as per the limit load without causing any permanent deformation to the structure. In order to find how much the stress the wings are subjected to, the procedure for the testing wings on the ground which is called as static test. Static test are carried on the test rig. Wings are mounted on this test rig to analyze the stresses. However these test rigs should be much stronger than the object to be tested on it. In this paper the design parameter such as design configuration given more importance in the development of the test rig. A finite element analysis was done on the model of the test rig to verify the parametric design. So by using ANSYS workbench analysis was performed. There is much deformation in the test rig. By making a suitable alteration on the existing model of the test rig the deformation can be minimized to a small value. Alteration was made to compare if the initial design was good or can be made better.
