Mechanical Modeling of Local Variable Load and Deform of Valve Slice
The damping valve structure of shock absorber usually takes throttle slice as the main part, when the pressure difference at both ends of the valve and the pretightening force of the valve slice can be overcome, annular gap will be formed between the valve body and slice to form throttle channel, so as to achieve the purpose of attenuating external vibration. In this case, the valve slice mechanical model is established, and the deflection formula under the nonuniform load is deduced, which can calculated the deformation of valve slice at any position, and the analysis of the influence factors is carried out, which lays a foundation for study the performance characteristics of the damping device.
