Topology Optimization of Thermally Actuated Compliant Mechanisms Using Node Design Variables
The topology optimization method of thermally actuated compliant mechanisms using node design variables method is presented.The projection function within defined sub-domain is used to represent the relationship of node design variables and node density variables in the method.It can impose the minimum length scale control during topological design.The topology optimization model of thermally actuated compliant mechanism is established by maximizing the output displacement and restricting the structure volume.The adjoint approach is applied to perform the design sensitivity analysis,and the method of moving asymptotes is adopted to solve the topology optimization problem.The numerical examples are presented to show that the proposed method can avoided the de facto hinges in the obtained thermally actuated compliant mechanism.
