【Abstract】 A deep study had been carried out on the design of the thickness of throttle valve plate of oil-pneumatic spring and of throttle chink.This paper also carried out research on how to design the damping coefficient of oil-pneumatic spring according to damping ratio,the damping force and the pressure difference for opening the valve of oil-pneumatic spring in accordance with coefficient of damping force,and on how to design the throttle valve plate thickness of oil-pneumatic spring by means of pressure difference for opening the valve.Mechanics model for bending deformation of throttle valve plate was presented and creatively put forward the coefficient method of bending deformation for the design of valve plate thickness.A study on the design of throttle chink has been carried out;a simulative analysis on the damping characteristics of all oil-pneumatic springs has been conducted,and finally the laboratory test on characteristics of resistance was performed on the being designed oil-pneumatic spring.更多还原
