Abstract


The use of ambulances transporting patients or severely disabled person , in order to avoid the deterioration of the illness or injury of the patient in the course of delivery , the movement for a smooth and high- speed . Data indicate that about 10% of the patients in the way the inevitable condition some deterioration , mainly because of the stretcher is directly connected to the ambulance bodywork vehicle during operation bumps up and down and the car starts , braking, acceleration, deceleration generated the impact directly acting on the patient , give the patient all the insecurity this has made ??a variety of attempts to try to minimize the adverse effects of vehicle vibration or shock to the patient . The use of modern design methods to the subject of research and development of a high quality and low price , to meet the market demand for the product , the theoretical analysis and computation and damping system . The main contents are as follows : ( 1 ) the use of a systematic design method , and program design of the the ambulance stretcher damping system . The study design the gas spring (2) , the use of its low rigidity to obtain a lower resonant frequency , thereby obtaining a comfortable transporting effect . VRLA two different cross - sectional area of orifice (3) According to the damping vibration damping characteristics , to generate airflow damping amplitude , so that the damping effect optimum . (4 ) to the ambulance floor bumps up and down and back and forth pitch as the vibration input , the calculation model for vibration analysis . The design methodology and calculation methods have the common sense , provides a theoretical basis for the design calculation of the vibration system .
