Problems encountered :
An equipment of analysis uses a disk in very fast rotation and illuminated by a laser. The disk is mounted on its axis by heat shrinking. The laser thermal solicitation must not overheat the axis and the motor, nor questions the shrink fit. Therefore, the set is validated by thermo mechanical simulation
Objective
Validate the shrink fit’s design in term of heat insulation and mechanical strength
Solutions
- Thermal simulation with the laser’s illumination averaged by the rotation.
- Mechanical simulation considering the preload due to the shrink fitting, and the dilation due to the heating during the laser’s illumination.
- Sensitivity analysis to mounting components sizings.
