Description

technical field [0001] The invention relates to the technical field of friction electrification, in particular to a detection and analysis device for friction electrification and static electricity dissipation in a space environment. Background technique [0002] Triboelectrification is a common physical phenomenon. Any two different objects will generate static electricity during the contact separation or friction process, and the accumulation of static electricity will easily lead to electrostatic discharge and cause harm. Especially in the field of aerospace, because it is in a vacuum or suspended state, the frictional charge on the surface of the material cannot be effectively and quickly dissipated or dissipated, and the electromagnetic pulse field generated by its electrostatic discharge will cause electromagnetic waves to various electronic equipment and information systems. Interference will cause the navigation system of aircraft, rockets, satellites and other aircr...
