This article presents the modeling and optimization design of a large load magnetic levitation gravity compensator. The proposed compensator comprises three layers 2-D permanent magnet (PM) arrays. middle mover layer can generate passive force to compensate for loads in some systems, such as measurement framework lithography machines or space optical equipment be tested on ground. To accurately predict force, an improved charge model is proposed, which actual working points each PM are...
With the advancement of manufacturing, precision requirements for various high-precision processing equipment and instruments have further increased. Due to its noncontact nature, simple structure, controllable performance, electromagnetic levitation has broad application prospects in ultra-precision ground testing aerospace equipment. Research on vibration isolation technology using is imperative. This paper reviews latest research achievements three types passive isolators five active...
Magnetic springs, which can be used to replace traditional mechanical have many advantages, such as necessitating no physical contact, generating friction, vibration or noise, and having a long lifespan. Nevertheless, their strong nonlinearity limits widespread application. In this study, we developed novel permanent magnet spring address issue: Halbach magnetic spring, with large levitation force an approximately linear characteristic curve. First, introduce the structure parameters of...
