As a floating raft air spring system tends to be large, the structural stiffness of the raft will inevitably decrease.Under the influence of external disturbance, the raft will deviate from the balance position and generate a large elastic deformation, which will result in relative displacement between devices on raft and affect operational safety.In this paper, a flexible raft response model of a floating raft air spring isolation device was established and a control method was proposed based on air spring parameter identification.The attitude and elastic deformation of the raft was controlled by adjusting the air spring pressure distribution.The test results show that this method can not only control the attitude balance of the raft, but also restrain the elastic deformation of the raft effectively, and has high control accuracy.
