The structural design of the spacesuit is important in advancing the future of Lunar and Martian space exploration. The spacesuit is designed considering the safety and comfort of the astronauts under various pressure and loading conditions. The design, manufacturing and experimentation of spacesuits require lots of money until perfected. To reduce the dependency on manufacturing the suits for testing, a high-fidelity model is created to simulate the static and low-velocity impact response of spacesuit using MSC NASTRAN and ANSYS, and later perform the experiment using the LVI machine. For this research, materials like intermediate modulus carbon fiber and fiberglass are considered and modeled in the analytical software allowing to perform structural static and dynamic analysis. The model will then be optimized to calculate the shape derivatives and handle multiple variable design and constraints using the continuum sensitivity analysis method.
