A simulated experiment platform designed for inhaled particles electrostatic monitoring is constructed, electrostatic sensors and SC-010 environmental chamber are used in the construction, simulated experiments on the characteristics of electrostatic induction of aeroengine inhaled particles are carried out by this platform, and the corresponding electrostatic signals are acquired successfully. Particle material, pipe flow velocity, particle size and particle mass concentration are set as experiment variables, and four groups of contrast experiments with different single variables are conducted in sequence. The electrostatic signals are acquired under different variable conditions, which included different particle materials, pipe flow velocities, particle sizes and particle mass concentrations; each kind of electrostatic signals and its activity level (AL), positive/negative event rate(PER/NER) and absolute average amplitude are analyzed and compared in this paper; some valuable conclusions are studied. The experiments found that four kinds of variable conditions mentioned above could have different effects on AL parameter, PER/NER parameter and absolute average amplitude.
