机箱机柜减震设计要注意什么?

发布时间:2021-12-10 来源:http://www.tongyuhengcheng.com/ 浏览量:

机箱机机柜的机械条件主要指的是在电子设备中使用的运载工具不相同条件下,离心加速度,冲击和振动的机械动作。机械条件的影响主要是在电子设备组件得电气参数、变化的电子元件,结构损伤,变形虎断裂失效。
The mechanical conditions of the cabinet mainly refer to the mechanical actions of centrifugal acceleration, impact and vibration under the conditions of different vehicles used in electronic equipment. The influence of mechanical conditions is mainly in the electrical parameters of electronic equipment components, changing electronic components, structural damage, deformation, fracture and failure.
1.降低振源强度
1. Reduce vibration source strength
高速操作的电子设备,为了有效地保证其动态平衡,可以通过减少生成不平衡位置振动,从而达到减震能力;对于舰载天线,可以把它的迎风面积优化设计,减少面积大小,从而减少风荷载减少振动;雷达电子设备、旋转等将和相关组件的生产轴承摩擦振动,有效缓冲设计需要配置精密轴承,从而减少摩擦。
For high-speed electronic equipment, in order to effectively ensure its dynamic balance, the damping capacity can be achieved by reducing the vibration of unbalanced position; For shipborne antenna, its windward area can be optimized to reduce the area, so as to reduce wind load and vibration; Radar electronic equipment, rotation, etc. will have friction and vibration with the production bearings of related components. The effective buffer design needs to be equipped with precision bearings to reduce friction.
2.通过对减振体进行消振来进行减震设计
2. The damping design is carried out by eliminating the vibration of the damping body
对于振源体产生的激振抑制效果不好或者是无法完成时,可以对减振体实施特殊设计,从而有效地完成消震。如特种设备安装特殊装置在弹簧减振器,它可以有效地吸收减少振动相互作用和减振体产生的动能来源,减少振动源的振动强度。

When the excitation suppression effect produced by the vibration source body is not good or can not be completed, the vibration absorber can be specially designed to effectively complete the vibration elimination. If special equipment is installed with special devices in the spring shock absorber, it can effectively absorb and reduce the vibration interaction and the kinetic energy source generated by the shock absorber, and reduce the vibration intensity of the vibration source.
3.可以通过隔离的悬架设计,即振动和减振源之间,插入衬垫达到减震效果,需要确保相应的柔软性,这样的振动源振动时将会发生变形,以减少振动强度。在电子设备中常用的衬垫为阻尼板。和具体实施方案,需要进行力学分析,以及各个组件之间明确物理机制分析,以便采取合适的悬挂方法。同时需要每个结构参数和悬架性能计算方法和定量数据,确定优先结构参数。
3. The damping effect can be achieved through the isolated suspension design, that is, insert the pad between the vibration and damping source. It is necessary to ensure the corresponding softness. Such vibration source will deform when vibrating to reduce the vibration intensity. The pad commonly used in electronic equipment is damping plate. And the specific implementation scheme, it is necessary to conduct mechanical analysis and clear physical mechanism analysis between various components, so as to take appropriate suspension methods. At the same time, each structural parameter and suspension performance calculation method and quantitative data are required to determine the priority structural parameters.
工业设计师在设计过程中,要把日常的设计经验积累运用起来,电气或机械设备本质核心是机械功能,他的外表是给人的展现方式,在功能上与外观之间还需要进行结构的合理设计才能让机械设备设计出来的机械产品风格更加鲜明。
In the design process, industrial designers should accumulate and apply their daily design experience. The essential core of electrical or mechanical equipment is mechanical function, and his appearance is a way to show people. In order to make the mechanical product style designed by mechanical equipment more distinctive, it is also necessary to carry out reasonable structural design between function and appearance.
