Concurrent Multiscale Topology Optimization for Designing Displacement Inverter

Abstract

Structural light-weighting is vital for increasing energy efficiency and reducing CO2 emissions. One of the mechanical structures that are used in numerous applications and can utilize light weighting is the displacement inverter. The displacement inverter is producing a mechanical reaction as the reverse of the input actuating action. In this research, multiscale topology optimization of compliance mechanism is used to design a lightweight displacement inverter. In this research, a hybrid topology optimization of SIMP for macroscale and ESO for microscale was used to obtain porous displacement inverter designs. Several numerical examples were investigated, and an experimental case was conducted by printing the design displacement model using 3d printer.
