Description

A kind of determining method of special vehicle vehicle thunder and lightning subregion emulation

Technical field

The present invention relates to a kind of special vehicle vehicle thunder and lightning subregions to emulate the method for determination, belongs to test and measuring technology is led Domain.

Background technique

Special vehicle is usually operated at field environment, and weather or geographical environment are more complicated, is especially in ward When, the probability being struck by lightning is bigger.There are certain damaging influences for vehicle for lightning effects caused by being struck by lightning, gently then Body construction is destroyed, it is heavy then personal safety can be endangered.

Generally, the lightning effects caused by special vehicle that are struck by lightning are divided into thunder and lightning direct effect and thunder and lightning indirect effect.Thunder and lightning Direct effect is directly to hit special vehicle to thunder and lightning, can lead to breakdown vehicle, melting, malformation hair etc., straight to avoid The harm of thunder bring is hit, lightning rod protection is generally installed to realize by special vehicle working region attachment, avoids thunder and lightning direct Hit vehicle.When thunder and lightning indirect effect refers to that thunder and lightning hits lightning rod, powerful thunder can be generated in thunder amplification current discharge process Electric electromagnetic pulse field leads to special vehicle electronic equipment performance degradation or is damaged.

Currently, due to the restriction of the conditions such as study subject and test site, lightning effects examination is carried out to special vehicle vehicle Test that there is also larger difficulty.Simultaneously because lightning effects have stronger destructiveness, it is easy to cause tested object irreversible Injury.Therefore, lightning effects simulation analysis just becomes and Lightning Test can be replaced for spy to a certain extent in this context The lightning effects of kind whole vehicle carry out forecast analysis and thunder And Lightning Preventive Measures are carried out with the means of assessment verifying.

For special vehicle vehicle lightning effects simulation analysis, be broadly divided into three parts: lightning leader adhering zone is imitated Exact fixed, special vehicle thunder and lightning direct effect simulation analysis and special vehicle thunder and lightning indirect effect simulation analysis, the present invention are main For first part.Lack both at home and abroad at present and the method for determination is emulated for the thunder and lightning subregion of special vehicle vehicle.Therefore, this patent It is proposed that a kind of special vehicle vehicle thunder and lightning subregion emulates the method for determination.
