The goal of this project is the development of a computer aided system for the design of actuator systems for laser micro adjustment. This system will speed up the conventional time consuming design process. A powerful, evolutionary algorithm is used to optimise an actuator system regarding several quality criteria. These include the suitability for the adjustment task, simplification of design and geometric constraints. A fast simulation of the effects of laser forming on actuator systems is needed for the assessment of the suitability for the adjustment task. Simple actuator systems can be handled by treating them as small robots and using inverse kinematics calculations. For complex actuator systems a tailored fast finite-element simulation system has been developed. This simulation system can calculate the effects of laser forming on actuator systems with the needed speed. Most used actuator systems are complex due to the high adjustment capability requirements. That is why it is important to be able to represent the effects of elastic bending and upsetting which come to the fore in complex actuator systems. The system produces the pareto-optimal set of best compromises between the criteria and enables the design engineer to select the best fitting alternative.
