Vibration isolation device for electronic product and design method thereof

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...

AI Technical Summary

Problems solved by technology

In actual engineering design, due to the limitation of adjusting the support position of the vibration isolator, it is difficult to achieve the coincidence of the center line of the stiffness of the vibration isolator with the center of mass of the equipment or on a straight line
