Abstract: The design of emergency communication vehicle involves multiple disciplines such as structural engineering, materials science, mechanics, thermodynamics, acoustics, electromagnetics, and comprehensive cabling. The continuous development of modern design technologies such as Computer Aided Drafting (CAD) and Computer Aided Engineering (CAE) has brought new opportunities for optimization design of emergency communication vehicle. In order to adapt to the new situation of integrated technology development for emergency communication vehicle, improve the overall performance and environmental adaptability of emergency communication vehicle, and introduce comprehensive optimization design methods, the optimal solution for the overall design of emergency communication vehicle can be obtained, avoiding defects and risks in equipment development, shortening the development cycle, and maximizing the overall performance and product quality of the product. Based on CAD and CAE design tools for visual modeling, through multidisciplinary optimization design and analysis such as mechanics, thermodynamics, electromagnetics, and digital wiring virtualization, the development of emergency communication vehicle is further improved, achieving rapid design and one-time success.
