Design and Mechanical Test for Helicopter-borne Display Console

In this paper, a lightweight display console with high stiffness and strength is designed for the helicopter platform. The vibration environment characteristics of helicopter platform are introduced first. Then the composite material display console is designed according to requirements, and the modal analysis is carried out. On the basis of the research, choosing appropriate vibration isolation system and using stiffness method to realize the decoupling of the whole system. Finally, the vibration and shock test for the display console and its installed devices is conducted, and the test is passed successfully. Results show that the design is reasonable and the vibration isolation system chosen is proper, satisfying the requirements of the strict helicopter platform environment. The method can provide a reference for the design and optimization of similar products.
