Thesis focuses on the process of dimensioning, designing, and manufacturing a wiring harness for an electrical race car, used in a Formula Student competition, utilizing the NX software from a German company Siemens. The work provides a detailed description of the design approach to designing, the use of software and its functionalities.
The content is divided into three main sections that build the knowledge required for independent wiring design of a vehicle. Every section is further divided into subparagraphs for clarity and easier understanding. The first section describes theoretical foundations of electrical engineering necessary for designing the wiring harness and provides and overview of the components used, such as wires, connectors and shielding, emphasizing their importance in integrating them into an electric race car. The second section introduces the concept of CAD, a summary of Siemens' and NX's history. Continuing with a detailed description of software's functionalities, including basic program settings, 3D space creation, assembly design, importing components and applying constraints. Further it illustrates the process of wiring harness design and the creation of a formboard with a simple example. The third section presents a practical example designed and developed using NX. It covers dimensioning for use in a race car, selecting automotive connectors, positioning of connectors and circuits as well as the final implementation of the wiring harness on the 3D model and its installation in the vehicle.
