In order to optimize the design of the orifice of the adjustable linear hydraulic shock absorber, a hydrodynamic model was established between the actual size of the orifice at all levels and the maximum adjustable damping force of the corresponding typical operating point. The relationship between the parameters of the model The relationship between the impact of research at all levels of the orifice precision machining requirements of the design method. The example design and the experimental study show that the requirements of the processing precision of the damping holes at all levels of the hydraulic shock absorber are not very high, but the design of the damping holes is optimized to ensure that the hydraulic shock absorber has sufficient adjustment Margin, but also a good rated working performance
