Bio-inspired design of shock absorber for electronic board of satellite

Abstract

In nature, various mechanisms help living organisms to survive. These mechanisms have been optimized over time in nature. Taking inspiration from these mechanisms in different industries can help solve problems. In this article, the chameleon tongue structure is used to reduce the shock on the electronic board of the satellite. To reduce the shock on the electronic board in the satellite, which is subjected to shock during launch and separation, a spring leg has been designed. To increase the range of frequency, in which the acceleration of the board is lower than the input acceleration, and also to improve this structure, conical springs were also investigated for the satellite board system. Various factors affecting shock transmission on the electronic board were investigated. The results show that at low frequencies (high shock duration), independent of the spring structure, the acceleration of the board is equal to the input acceleration. The results show that the designed spring legs reduce the amount of shock on the electronic board compared to the rod leg.
