Millions　of　joints　are　utilized　in　large-scale　equipment　to　interconnect　components.　However,　the　intricate　nonlinear　mechanical　behavior　exhibited　at　joint　interfaces　poses　challenges　in　accurately　modeling　equivalent　joints.　The　Jenkins　element　with　viscoelasticity　is　built　upon　the　Iwan　model,　and　a　novel　Iwan-Stribeck-RIPP　(Reduced　Iwan　Plus　Pinning)　model　is　proposed　to　depict　the　slip　velocity　and　pinning　effects　concurrently.　Analytical　expressions　for　force-displacement,　energy　dissipation-displacement,　and　force-energy　dissipation　under　microslip　and　macroslip　were　derived.　A　joint　interface　experimental　platform　was　constructed　to　reveal　the　influence　of　slip　velocity　on　the　joint　interface.　The　results　indicate　strong　alignment　between　the　analytical　solution　of　the　Iwan-Stribeck-RIPP　model　and　the　experimental　outcomes　of　the　joint　interface.　Moreover,　the　model　effectively　captures　both　slip　velocity　and　pinning　effects.　Introducing　slip　velocity　into　the　new　model　promises　to　enhance　the　accuracy　of　force-displacement　analysis　at　the　joint　interface.　This　enhancement　is　attributed　to　the　inclusion　of　both　frictional　energy　and　kinetic　energy　dissipation　resulting　from　the　slip　velocity　in　the　analytical　model　of　the　joint　structure.　©　2024
