Multivariate Modeling of Design Parameters of Elastic Clips of Modern Rail Fasteners, with Analysis of Their Stress-Strain State

Purpose: To determine the influence of geometric parameters on most common elastic rod clip used in modern intermediate rail fastenings — B-shaped (such as reinforced concrete (RCR) and anchor fastening (ARF)) changes its stress-strain state. propose a further direction improving design clips fasteners to increase reliability structure. Methods: The article presents results multivariate modeling (RCR 20 pcs., ARF 13 pcs.) with analysis their state, using methods software computer systems SolidWorks Ansys Workbench. Results: Analysis has shown that intervals for varying (rod diameter, vertical radius, horizontal radius) have small limits significant limitations associated requirements ensuring strength, elasticity operability entire fastening. necessity considering options radii less than 60 mm been revealed, which entails need radical change shape themselves. Practical significance: As result calculations multivariant models, degrees variation state determined. It is established order clips, it necessary develop new type fundamentally different (different from B-shaped) does not parameters.
