Topology Optimization

Desk Specifications and Assumptions

1. Given dimensions: 30" high, 24" deep, 60" wide, 2" thick (made of nylon)
2. Setup for optimization
   • The legs are fixed to the ground
   • Gravity is the only external load centered on top of the table
   • Keeping the overall leg shape so the outlines are set as preserved regions
   • Cutting the mass down by 80%

Desk After Optimization

Chair Specifications and Assumptions

1. Material is also nylon
2. Should fit under the table with room for a person’s legs
   • Cut down by 8" to model a real chair/table
3. Must have some form of backing
4. Must be able to hold a 150 kg person
   • Ran an FEA to determine stresses and FOS
5. Setup for optimization
   • The legs are fixed to the ground
   • The external load of the person is present
   • Cutting the mass down by 60%
   • The outlines of the legs are preserved regions
