ABSTRACT
Objective To develop a new quasi-zero stiffness isolator for the vibration isolation of the sick and wounded on the ambulance stretcher.Methods The isolator was designed and verified on the basis of the quasi-zero stiffness of slotted disk spring, vibration isolation design method with high static while low dynamic stiffness and co-laminated structure of the spring.Results The theoretical analyses and tests proved the force-displacement curves of the new quasi-zero stiffness isolator fit well. The frequency-weighted acceleration at the buttock and head under different speeds on the asphalt roads was less than 0.315 m/s2.Conclusion The new quasi-zero stiffness isolator developed behaves well in vibration isolation and comfortability for the ambulance stretcher sick and wounded.
