Study on two dimensional base-isolating device for sick person´s bed in ambulance

This paper deals with two dimensional base-isolating device for sick person´s bed in ambulance. This device does the reduction response acceleration by using pendulum type inclination chassis on horizontal direction. And, this device does the reduction of relative displacement and response acceleration by using restorative force from compression spring and friction force on vertical direction too. The performance check of a base-isolating device is shown from experiment in a base-isolating device by an ambulance and Conduct simulation analysis and the experiment using vibration exciter using the experimental result by an ambulance.
