説明

In this paper, we present a method for reducing shocks experienced by patients when ambulances pass over humps which have been built on roads as a means of reducing speed of vehicles. It seems that the shocks affect ambulances that rapidly arrive at a scene of an accident and transport patients to hospitals, when the shocks are large. As a result of optimization of air springs and dampers of vibration isolaling beds for the ambulances, the optimum values of stiffness of the air springs and damping coefficients of the dampers are obtained and the shocks are reduced. The effect of variation of the factors on the maximum acceleration of patients is clarified, and the acceleration is compared with the maximum acceleration of drivers in passenger cars.
