Additive manufacturing of Airless tyres l based on polymer extrusion technique in Abaqus(AM PLUGIN)

In FEA basic aim of 3d printing simulation is to predict thhe excessive distortion and residual stresses during rapid heating and cooling of the part during printing. The airless design taken in this study is from Bridgestone tyres. This airless tire technology features a unique spoke structure designed to support the weight of a vehicle, effectively eliminating the need to periodically refill the tires with air.
Additive Manufacturing (AM) is an appropriate name to
describe the technologies that build 3D objects by adding
layer-upon-layer of material. In this simulati0n progressive material addition based on polymer extrusion technique is used to deposit layer of material. In Polymer extrusion technique an extruder puts down molten beads on top of a previous layer and as they solidify, they fuse to the
existing part
Abaqus Modelling
A coupled thermo-mechanical simulation is performed in abaqus using Polyurea as a base material. First, a heat transfer analysis is performed on the part with appropriate and specific temperature boundary conditions and flux
loads(laser) Once the heat transfer analysis is complete, the temperature profiles are used to drive a static analysis of the part to predict distortions. Position and time of the laser is specified by entering event series data that comes from the NC codes generated by conventional Softwares Replicator/creo-CAM. Also from the stress analysis of the tyres for the existing material model it was observed that these tyres can easy withstand load of 700-1000kg with deformed excessively.
