Abstract :
Dual-chamber pneumatic springs are widely in the vibration system for precision instruments, its controller design and structure optimization requires an accurate model. The top chamber model is an important and complicated part of the model for its volume variety caused by piston movement and rubber deformation. In order to obtain top chamber volume characteristic, a hyper-elastic constitutive model of rubber has been established firstly, then a fluid-structure model of top chamber is built in ADINA. By analyzing simulation results, the influence of piston displacement and rubber deformation on top chamber volume is concluded finally.
