Parameterized modeling and selection analysis of geometric parameters:
According to the GB/T 1972-2023 standard, input the thickness (t), outer diameter (De), inner diameter (Di) and free height (ho) of the disc spring, and calculate key ratios such as ho/t and De/t to determine the A/B/C series selection. Material properties:
Define the elastic modulus (E), Poisson's ratio (μ) and yield strength (Os), and the nonlinear correction coefficient (K) must be adjusted accordingly according to different series (A/B/C series).
Finite element simulation and verification Model construction: Use professional tools such as SolidWorks to build a geometric model of disc springs. End processing: Perform self-contact analysis of the closed end to ensure that the model does not have merging during the simulation process. Boundary conditions: Apply axial load, simulate the compression and rebound process of the disc spring, and monitor the stress distribution and deformation amount in real time. Set limit displacement constraints (for example, Slim=0.75ho) to prevent failure caused by overload. Verification: By comparing theoretical calculation data and simulation data, quickly verify the feasibility of the solution.
SUNZO has it’s own researching and development team and test center, has participate in rule-making of the latest national industry standards and the international ISO standards for disc springs.
