Manzhilevskyy O. Hydraulic impulsive drive of installation for vibroabrasive processing parts of complex configuration

Object of research - the dynamic processes occurring in hydraulic impulsive drives of installation for vibroabrasive processing; objective of work is to improve process performance vibroabrasive processing parts of complex configuration by imposing external complex dimensional vibration by working links with hydraulic impulsive drives; methods of research: methods physical and mathematical modeling based on fundamental laws of mechanics of solids, theory of hydraulic drive and hydro using computer simulations based on package MATLAB 6.5; methods of strain gauges recording measurements using analog-to-digital converter and a PC and an assessment of their error methods of mathematical statistics, theoretical results: further developed the basic theory vibroabrasive processing parts of complex configuration during their forced movement in abrasive environments due to external complex dimensional vibration load working links with hydraulic impulsive drives; first developed a mathematical model workflow of hydraulic impulsive drives of installation for vibroabrasive processing surfacing parts of complex configuration in which the hydraulic link is represented as a visco-elastic model that can reveal patterns of complex dimensional vibration and its relationship the process vibroabrasive processing; first developed a mathematical model of movement of plunger plunger's cylinder and the analytical dependence, which allows to calculate the performance kinematic parameters (displacement, velocity and acceleration) of plunger, the main design parameters and the magnitude of the pressure in the cavity of the cylinder, first proposed traffic control abrasive environment by vibrating movement working links with hydraulic impulsive drive in three independent directions. Practical results - based on theoretical and experimental studies the experimental setup with complex dimensional vibration for vibroabrasive processing parts of complex configuration in which the drive uses vibrating cylinders of original design with a wide range of operating parameters regulation that significantly expands technical capabilities of hydraulic impulsive drives of installation for vibroabrasive processing; substantiated selection of key process parameters of vibroabrasive processing parts of complex configuration using complex dimensional vibration loads; developed design documentation for the node hydraulic impulsive - vibrating cylinder; developed guidelines for determining the required power electric pump of hydraulic impulsive drive and feed of pump. Degree of implementation - the main results of the thesis introduced at JSC "Avtoelektroaparatura". Scope (industry) use - enterprises engaged in vibroabrasive processing of parts.
