Hub bearing is a kind of bearing with relatively high technical complexity, which is directly related to the safety and comfort of automobile. The difference between the traditional hub bearing structure and the traditional hub bearing structure makes the stiffness requirements more strict, so it is particularly important to carry out the stiffness analysis and test. Analysis and experimental research provide guidance documents for product development and optimization, save a lot of development costs, provide a good foundation and platform for enterprise product development, and have great economic prospects. The main contents of this paper are as follows:<br>(1) According to the structural parameters of the hub, the ABAQUS three-dimensional parametric model is established.<br>(2) Analyze the load characteristics of the hub shaft, set the corresponding and boundary conditions according to the actual working conditions, and get the corresponding deformation and stress results<br>
