Abstract
The article describes the creation of a 3D model of the steering knuckle of the “Formula Student” class car using the SolidEdge CAD / CAE system application, named generative design. The initial data are a model of an overly strong steering knuckle, previously calculated load values for various operating modes, information about the properties of the material. In the process of optimization, technological settings are varied in order to obtain a geometry that is as suitable as possible for cutting on a three-axis milling machine with a CNC and without an additional rotary axis. The result of the generative design is used to build a model of a knuckle that can be milled with repositioning and clamped into universal fixtures such as a vise. The construction is carried out using standard solid modeling tools (lofting by sections, adding thickness, etc.). Fastening elements have been added to the part, in the form of rectangular bodies, which will need to be removed using manual cutting and grinding operations after the milling operations are completed. Additionally, holes are removed parallel to the Z axis, which can only be made after cutting the fasteners.
