Abstract

In this research, the laptop stand made from waste drum brake shoe material will undergo variations in mass reduction through the stages of static structural simulation and topology optimization using Ansys Workbench to achieve mass reduction, total deformation, equivalent stress, and safety factor for each mass reduction variation. The laptop stand geometry will be subjected to a load of 44 N and supported as needed. Based on the simulation, the initial design of the laptop stand produces an equivalent stress of 2.07 MPa, total deformation of 0.08 mm, and a safety factor of 12.46. For the 50% mass reduction variation, the data obtained was: equivalent stress 2.78 MPa, total deformation 0.11 mm, safety factor 13.858. For the 75% mass reduction variation, the data obtained was: equivalent stress 3.06 MPa, total deformation 0.26 mm, and safety factor 8.42. For the 80% mass reduction variation, the data obtained was: equivalent stress 3.88 MPa, total deformation 0.40 mm, and safety factor 6.63. For the 85% mass reduction variation, the data obtained was: equivalent stress 14.14 MPa, total deformation 0.89 mm, safety factor 1.82.
