Numerical analysis of leaf spring stacks, often used in freight wagon design. 2. Key Input Parameters A full technical analysis using OPRUGA typically requires: Material Properties: Shear modulus ( ), tensile strength ( Rmcap R sub m ), and allowable shear stress ( τallowedtau sub a l l o w e d end-sub ). Common materials include spring steel (e.g., 51Si7). Load Requirements: Minimum ( F1cap F sub 1 ) and maximum ( F2cap F sub 2 ) operating forces. Dimensional Constraints: Maximum outer diameter ( Decap D sub e ) or minimum installation length ( L0cap L sub 0 3. Typical Output (Report Content) Numerical analysis of leaf spring stacks, often used
