First, ensure the realization of product technical indicators.
In the process of chassis design, electromagnetic interference and thermal influence between components in the chassis should be considered to improve the stability of electrical performance; Be sure to pay attention to the strength and rigidity of the chassis to avoid deformation, poor electrical contact, truck doors and connectors, and even damage after vibration; According to the actual working environment and use conditions, corresponding measures should be taken to improve the reliability and service life of equipment and ensure the realization of product technical indicators. ?
The second is to facilitate the operation, use, installation and maintenance of the equipment.
In order to operate and use the equipment effectively, the structural design of the chassis must conform to people's psychological and physiological characteristics, and at the same time, it is required to be simple in structure and convenient to disassemble and assemble. The controller and display device on the panel must be selected and arranged reasonably, and the personal safety of the operator should be considered.
Third, good structural manufacturability.
Structure and technology are closely related. Different structures will lead to different technologies, and the quality of chassis structure design must be guaranteed by good technical measures. Therefore, designers are required to consider the manufacturability of their structures in combination with production practice.
Fourthly, modular and standardized design.
Standardization is an important technical and economic policy and management measure of the country, which plays an important role in improving product quality and productivity, facilitating use and maintenance, strengthening enterprise management and reducing production costs. In the structural design of chassis, it is necessary to reduce the number of special parts as much as possible, increase the number of general parts, and adopt standardized parts and size series as much as possible (using standard library and national standard parts as much as possible).
Modularization is the development and advanced form of standardization, which can be combined into a new system and easily disassembled and replaced from the system. Modules are typical, universal, interchangeable or compatible. Standardization and generalization are interchangeable only at the component level, while modularity is interchangeable at the component level, even at the subsystem level, thus achieving a higher level of simplification.
It should be noted that machine obstacles will inevitably be encountered during the use of the chassis. At this time, we need to disassemble and maintain it, so modular design is particularly important at this time. In the chassis, the calculation module is the core component, and the maintenance rate accounts for 80% of the whole machine. In order to facilitate maintenance, a three-layer quick release mechanism is designed at the front end of the module: panel quick release; Fast release of fan module; Quick release of computing module. The design of these three mechanisms should support unarmed operation, and the structure space is compact, convenient and practical.
