摘要 提出环形阀片受相关载荷作用时挠曲变形量的一种研究方法。建立阀片的物理模型,利用薄板变形微分方程以及内外径处的边界条件推导环形阀片受均布载荷作用时的挠曲变形解析式,整理得出了便于理论分析和工程应用的表达形式。与现有技术中环形薄板近似解对比验证了公式的正确性及其优越性,研究了不同载荷以及节流阀片相关结构参数和材料特性对其任意半径处变形量的影响规律。得出的解析式和结论为减振装置阻尼阀的精确设计提供了依据。 We present a method for computing annular slice deflection. The physical model of throttle slice was built. The equation for deformation under a uniform load was deduced by using a deflection differential equation for throttle slice and boundary condition, which was convenient for theory analysis and engineering application. Equation correctness was validated by comparing the approximated result in the existing technology. We subsequently studied the rules of different loads, structure parameters, and material characteristics of throttle slice influence on the deformation at any radius. The equation and conclusions can serve as references for accurately designing shock absorber throttle valves.
