Validating and optimising bolted joint design delivers safety and performance improvements, alongside streamlining costs. There is now a powerful new vibration test methodology using controlled shear force loading. It is significantly more advanced than traditional – and flawed – displacement amplitude-driven Junker testing. This new approach enables users to test bolted joints for resistance to rotational self-loosening under real-world conditions.
