Embodiment Construction

[0033] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0034] see figure 1 , assuming that Z1 is the geometric centerline of the electronic device 3 in the X-axis direction, the total mass of the electronic device 3 is M, and the center of mass of the electronic device 3 is at A, that is, the center of mass is not on the geometric centerline Z1, and is offset in the X-axis direction The geometric centerline Z1 distance is X0. If the same vibration isolator is used to isolate and buffer the electronic equipment 3, although the support stiffness centerline composed of the same vibration isolator coincides with the geometric centerline Z1, the support stiffness centerline and the center of mass of the electronic equipment 3 are at X The axis directions do not coincide, which will inevitably produce a vibration coupling effect and aggravate the damage of the electronic device 3 . In order to avoid the vibration couplin...

Abstract

The invention relates to a vibration isolation device for an electronic product and a design method thereof. The design method includes the steps of firstly determining the static load, stiffness energy capacity and the like of a vibration isolator 1 and a vibration isolator 2 in the principle of the requirement that the center of mass coincides the center line of the stiffness in accordance with the conditions, such as the total mass, the location of the center of mass and the dimension of an electronic device, the space, location, number and mode of the installation of vibration isolators and the peak response frequency of the isolation device; finally selecting vibration isolators of appropriate stiffness to form the vibration isolation device composed of vibration isolators of different stiffness for isolation and buffering for the electronic device. The vibration isolation device for the electronic product can effectively avoid the vibration coupling effect and greatly improve the anti-vibration and anti-shock performance of the electronic device. Therefore, the design technology such as the design method and idea of the vibration isolation device for the electronic product is reasonable and feasible, can be popularized and applied to the field such as other military and civilian products and has good popularization and application prospects.

Description

technical field [0001] The invention belongs to two technical fields of machinery and vibration, and specifically relates to a vibration isolation device for electronic products and a design method thereof, which can be applied to fields such as military industry and civilian products, and is especially suitable for airborne millimeter-wave radars. Background technique [0002] With the advancement of science and technology, more and more electronic products are used in harsh environments, requiring products with higher safety and reliability. There are many factors that affect the safety and reliability of electronic products. In addition to temperature and humidity, vibration and shock are the most important factors. Therefore, the vibration and shock of electronic products has become a problem that must be considered in product design. [0003] When designing the vibration and shock of electronic products, an appropriate vibration isolator or shock absorber should be inst...
