 Report on research work: 39 pages, 5 figures, 15 sources. AIR PURIFIER, ROTATING WORKING BODIES, PARTICLE TRAJECTORY, MODELING, OPTIMIZATION. The object of research is the active rotating working bodies of the air purifier from wood particles. The purpose of the work is to develop a methodology for optimizing the parameters of the active working bodies of the air purifier from wood particles. Research methods: analytical modeling of the movement of wood particles in the area of action of the rotary working bodies of the purifier using the methods of physics and aerodynamics; simulation of the vibration load on the supports of rotating working bodies, caused by their imbalance, using the methods of machine vibration theory. The obtained mathematical model of the work process of the air purifier with active working bodies makes it possible to determine the possibility of the purifier catching particles of a certain size (limiting speed) and can be used in the optimization of their design and technological parameters according to the criterion of minimizing the limit speed of particles caught by the purifier. The economic effect of optimizing the parameters of the air purifier is due to a more complete cleaning of the dust-air mixture from wood particles, which makes it possible to use them as material for further processing. The research also has social significance, as it makes it possible to improve the working conditions of workers due to the reduction of the concentration of wood particles in the air. A promising direction of further work is the improvement of the model of the work process in the air purifier, namely, three-dimensional computer modeling of the movement of wood particles.
