Brief introduction

Electronics equipments while vibrating environment, because of oscillatory of tired effect and resonance phenomenon, probably appear to give or get an electric shock function to descend, zero parts expiration, tired hurt even break of phenomenon.According to the statistics, in the middle of arousing the environment factor that the machine carries(play to carry) electronics equipments expiration, vibrate a factor to have 27% around.So, carry on to the structure excellent turn a design,

The anti- that raises an equipments vibrates ability, promising the important means of product function and credibility.The electronics equipments is flapped a source to deliver come of force a vibration, flapping of dissimilarity source, different vibration environment,

It isn't same to the influence of the product.The car carries equipments and the vibration environment in the conveyance is win the random vibration of low frequency, the vibration of perpendicular direction gains advantage, the vibration quantity of the level direction's being worth is farer small than vertical stalk.On the jet plane and the guided missile, its flapping a source is a motor to compatibly move Rao to flow, and land, skidding opportune moment body of vibration, its vibrating environment is a breadth to take random vibration, the encouraging of perpendicular direction and level direction measures a value very.Warship ship's mainly flapping a source is the low frequency period that the propeller produces to vibrate.Generally speaking, in order not to resonance phenomenon, the proper frequency of electronics equipments should avert from to vibrate incentive frequency, their specific value should be bigger than 2.5, call it as doubly and repeatedly rule.But take to vibrate environment in the breadth in, this is can not do it, cans make to lower resonance Feng a value and deliver rate and related Ou to match a rate.Therefore, need the proper frequency to reach the piece to the system and the inner part and mold Tai to carry on analysis, come to excellent design for turning structure.
