Lateral Stiffness Simplified Calculation for Flexicoil Spring with Rubber Pad on One End of Railway Locomotive and Rolling Stock

Article Preview

Abstract:

Based on classic lateral stiffness analysis theory of flexicoil spring and rubber pad, the mechanical model and mechanical relationships of flexicoil spring with rubber pad on one end are established, and the simplified calculation formula for the lateral stiffness of flexicoil spring with rubber pad on one end is derived. By contrasted with experimental results, the theoretical lateral stiffness values of the derived simplified formula are in good agreement with the experimental results, so the derived lateral stiffness simplified calculation formula is correct and accurate. The result of this simplified lateral stiffness calculation formula can meet the requirements of engineering theoretical analysis, this calculation method can provide theoretical basis for such structures design and application, and provide parameters for dynamic calculation of railway locomotive and rolling stock.
