This paper presents research on numerical simulation of the micro-assembly of MEMS devices. Recent developments in MEMS devices ñ making use of multiple deposition layers, micro-fabricated hinges, and actuators ñ have enabled fabrication of MEMS devices that can deform out of plane. Applications include latching mechanisms and tilting mirrors. The simulation methodology has been developed which allows a MEMS designer to take into account the required actuation forces, interfacing mechanisms, and time constraints for micro-assembly. The simulation results rely on multi-stage contact analysis, dynamic analysis, and large displacement theory. Results will be presented for two case examples.
