BPN370: MEMS Metal Gimbal: Design and FEM


The long range goal of this research is to analyze the a UC Berkeley designed MircoGimbal with a finite element method (FEM) simulator, ANSYS, to achieve design optimization. A fundamental design goal of the MicroGimbal is to maximize the rotation angle (current target is +/- 30 degrees) while minimizing the stress. TheorticallyTheoretically, it can be obtained by having cross section with low moment of inertia and long length . However, low moment of inertia and long length reduce the beams ability to support the payload in z-direction. Due to these competing phenomena, optimization of the UC Berkeley MicroGimbal elements is essential.
