The research was conducted in the frame of the project “Metamorphosis”. The project objective is to develop a prototype of an intermodally transportable space environment testing facility. The research is focused on development of the Vacuum Chamber for the Space environment simulation for smallsize satellite system CubeSats testing purposes. The Vacuum Chamber should be designed to be mobile or intermodaly transportable. A basic transport unit for the Vacuum Chamber was taken a vehicle that will be designed as a mobile laboratory. This research phase focuses on the Vacuum Chamber rigidty testing on transportation loads caused by vibration. The testing is conducted using the analytical approach into virtual environment with ANSYS software. The analyses procedure in the virtual environment is completed in several steps that are necessary to obtain the desired results. The main work is in preparation of the model, defining materials, connection types. The obtained results will be avaluated and used in the further design process. If it is necessary, revisions will be made in the Vacuum Chamber CAD design model to make the system design rigid enough to withstand transportation vibration loads like truck transportation, railroad transportation and others as well. The obtained results showed that some system construction redesign is necessary.
