Abstract
This paper discusses macro-geometrical, micro-geometrical and biomechanical features of eggshell, and proposes its inspiration for bionic design of submersible pressure hull. The results show that eggshell has excellent bionic performance on the weight-strength ratio, the span-thickness ratio, the aesthetic characteristics, the distribution of material and so on. The pressure endurance of the eggshell under uniform pressure is quite remarkable. Bionic design based on eggshell structure can effectively coordinate variable features of deep-sea pressure hull such as strength, stability, reserve buoyancy, streamline shape, space utilization in the crust and occupant comfort.
