Description

technical field

[0001] The invention belongs to the field of electronic equipment, and in particular relates to a structural optimization design method for high-density and complex airborne chassis electronic equipment. Background technique

[0002] The chassis of electronic equipment is a basic structure that assembles various electronic components or mechanical parts inside the equipment into a whole, exempts it from the influence and interference of various complex environments, and ensures electrical performance. As the chassis of modern military electronic equipment used in high-tech products, it must not only meet the functional requirements of the equipment, but also meet the environmental requirements of the equipment. A well-designed electronic chassis can make the equipment withstand strong vibration shock, electromagnetic interference and relatively harsh weather conditions, which is the basis for improving the reliability of modern electronic equipment.
