Problems solved by technology

The static electricity generated by the mutual movement and friction between particles in the particle environment will form a strong electrostatic field locally. Existing studies have shown that the electrostatic field in the particle environment will have serious adverse effects on high-voltage power transmission and microwave transmission.
However, the effect of charged particles and electrostatic fields in the particle environment on the tribological properties of mechanical systems is unclear

Description

technical field [0001] The invention relates to a particle environment simulation system, more specifically, to a particle environment simulation system with the function of particle motion triboelectrification measurement. Background technique [0002] As a typical service environment, the particle environment is increasingly affecting people's production and life. The dust particles suspended in the air have a great impact on the service and life of mechanical equipment, especially precision machinery, such as magnetic head magnetic card systems and air bearings. Therefore, the design and application of mechanical equipment have to consider the impact of the particle environment on the service state of the equipment. The static electricity generated by the mutual movement and friction between particles in the particle environment will form a strong electrostatic field locally. Existing studies have shown that the electrostatic field in the particle environment will have se...
