ISS Model

ISS 3D model

In the CAD class in 2020 fall, we tried our best to construct a 3D model for the International Space Station (ISS). Each mechanism and dimension was carefully researched so that it could be as close to the actual ISS as possible.

Harmony

This module is equipped with the Pressurized Mating Adapter (PMA), which serves as a docking port with modules or spacecraft, long- or short-term.

Pressurized Mating Adapter (PMA)

With an intricate mechanism capable of six-degree-of-freedom movement, this adaptor is crucial for docking in space.

The passive and active hooks are used to lock the other side up so that the passage could be safely pressurized for the astronauts to go through.

There are multiple components to facilitate this docking mechanism. To complete this model, I had to refer to the official NASA files describing the docking system. 

Static Analysis

When a module is performing the docking mechanism, a sudden force would exert on the receiving rings when the two spacecraft touch. It is therefore important to know how the structure would perform when this happens: the stress, the deformation, and safety factors.
