      機箱機柜減震設計要注意什么?

      發布時間:2021-12-10 來源:http://www.8477k.com/ 瀏覽量:

      機箱機機柜的機械條件主要指的是在電子設備中使用的運載工具不相同條件下,離心加速度,沖擊和振動的機械動作。機械條件的影響主要是在電子設備組件得電氣參數、變化的電子元件,結構損傷,變形虎斷裂失效。
      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.降低振源強度
      1. Reduce vibration source strength
      高速操作的電子設備,為了有效地保證其動態平衡,可以通過減少生成不平衡位置振動,從而達到減震能力;對于艦載天線,可以把它的迎風面積優化設計,減少面積大小,從而減少風荷載減少振動;雷達電子設備、旋轉等將和相關組件的生產軸承摩擦振動,有效緩沖設計需要配置精密軸承,從而減少摩擦。
      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.通過對減振體進行消振來進行減震設計
      2. The damping design is carried out by eliminating the vibration of the damping body
      對于振源體產生的激振抑制效果不好或者是無法完成時,可以對減振體實施特殊設計,從而有效地完成消震。如特種設備安裝特殊裝置在彈簧減振器,它可以有效地吸收減少振動相互作用和減振體產生的動能來源,減少振動源的振動強度。

      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.可以通過隔離的懸架設計,即振動和減振源之間,插入襯墊達到減震效果,需要確保相應的柔軟性,這樣的振動源振動時將會發生變形,以減少振動強度。在電子設備中常用的襯墊為阻尼板。和具體實施方案,需要進行力學分析,以及各個組件之間明確物理機制分析,以便采取合適的懸掛方法。同時需要每個結構參數和懸架性能計算方法和定量數據,確定優先結構參數。
      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.
      工業設計師在設計過程中,要把日常的設計經驗積累運用起來,電氣或機械設備本質核心是機械功能,他的外表是給人的展現方式,在功能上與外觀之間還需要進行結構的合理設計才能讓機械設備設計出來的機械產品風格更加鮮明。
      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.
