Electrification Theory and Experimental Research of Aluminum-Based Metallic Material

Aluminum-based metallic material as the frame or the skin material is widely used in vehicle industrial production. The electrostatic charge accumulate on the surface of the material,because of triboelectrifiction with space particles. And the electrostatic discharge would impact the vehicle or appliance around enormously. In order to study the triboelectrifiction, principle of space particle and space charge is analyzed and theoretical calculation formula is derivate. The fact is found that the charge of material is growth in negative index with time dependence, and get steady at the end. The saturation value and saturation time will be decrease when the charge factor of space charged particle increases. To make sure the conclusion is right, a part material of one aerial vehicle is taken into the test. From the experimental results of different material, angular velocity and contact area, the conclusion gotten above is proved by test data.
