Numerical Simulation of Re -Extrusion Process for Self -Lubricating Spherical Plain Bearings
Translated Abstract
The forming process for large self -lubricating spherical plain bearings is numerically simulated by using software Abaqus.The assembly forming mechanism for self -lubricating spherical plain bearings is studied by analyzing equivalent stress distribution,equivalent plastic strain distribution,variable curve for extrusion force and contact pres-sure distribution curves of liner for bearings during extrusion process.The result show that compared to second extrusion forming,the change of extrusion force is more stable and the equivalent stress and plastic strain is smaller during first extrusion process.After first extrusion,the waist of liner has the biggest contact pressure while both ends of liner have bigger contact pressure after second extrusion.
