Optimization Design of Nickel-Titanium Shape Memory Alloy Anti-Loose Gaskets Based on ABAQUS Numerical Simulation

The shape memory effect and superelasticity of nickel-titanium shape memory alloys offer substantial benefits for anti-loose devices. This study presents the design of an anti-loose gasket utilizing these alloys. A finite element numerical model of the gasket is developed using ABAQUS software, incorporating the superelastic constitutive model, to examine its deformation and stress under three distinct loading conditions: pre-tightening, tightening, and unloading. Based on the findings from the numerical analysis, we propose an optimized design for the gasket's size and shape to augment its anti-loose efficacy and adaptability. This investigation lays a foundational theoretical framework and offers technical insights for employing shape memory alloys in anti-loose device engineering, underscoring its significant practical implications.
