TEAM 13432
MSD 1 System Level Design Review
Biomass Compressor
Terminology
Biomass – any grown organic matter to be used in the system Compressor – increases pressure on the biomass FVP – force versus power TIE – team industrial engineering TC – team compression TSP – team slicing and packaging
Goals
• Present design criteria and customer needs for approval by customer
• Update customer in regards to concept generation
• Settle upon final systems architecture for approval by customer

Feasibility Analysis
Feasibility Analysis
What the mechanical testing will answer1. What does the force v. displacement curve look like?2. Does moisture have an effect on the results?3. Is the compressed material isotropic or an-isotropic?4. What are the effects of the three different materials?5. What is Poisson’s ratio for the materials tested?6. What are the effects of the orientation of the material on resulting
forces?7. What is the force needed to eject the brick from the compression
chamber?8. Do the results scale?9. What are the effects of dwell time in compression chamber?10. What is the maximum achievable density of brick?11. How does friction affect the compression and ejection of the
biomass?
