This finite element thermal analysis (FEA) examines the heat tolerance for a robotics component.
A single domain heat conduction analysis is performed on the nearest robotic component to the heat producing circuit board. The analysis is then extended to perform a parallel Design of Experiment (DOE) analysis to calculate temperature as a function of thermal conductivity. A desired thermal conductivity of the composite material is chosen through linear fitting to keep the robotics component below shut off temperatures.
The robot arm model was created in Onshape. The exported CAD STL is provided with this entry. To learn more about Onshape go to:
