Passive magnetic gravity compensation may be a very feasible alternative to commonly used mechanical or pneumatic solutions for vibration isolation systems. The final paper discusses a study on the optimal design of a magnetic spring with passive gravity compensation. For vibration isolation systems it is often preferred to combine a certain force level with very low spring stiffness to achieve a low resonance frequency. Several optimization methods are used in the paper to optimize the dimensions of planar magnet structures to exhibit a certain vertical force with low stiffness and the optimized results are compared. The results from this study give insight in the influence of topology choice on the achievable vibration isolation performance of permanent-magnet based springs.
