In combination with research situation of ball screw at home and abroad
a ball screw and nut raceway and the raceway model of analysis and contact finite element model is established.The nut axial elastic deformation data under the applied axial force is obtained and the simulation of ball screw axial contact deformation is carried out.By using finite element contact analysis results
the rationality of simplify model is verified.It has a certain theoretical value and practical significance.
