Abstract
The article deals with the solution to identifying the mathematical model parameters of a vane air motor, which are quite difficult to determine experimentally in a really working device. Such as: effective cross-sectional areas of leaks through gaps, friction coefficients of vanes on stator and rotor slots, heat exchange parameters of the working fluid with the chambers walls and some others. The solution was based on the parameter space research method implemented in the MOVI (Multicriteria Optimization and Vector Identification) software package. The adequacy criteria were compiled as the difference between the experimental and calculated values of the shaft power, compressed air consumption and exhaust temperature. Finding the only Pareto-optimal vector of identifiable parameters gives the desired solution. The found values of the required parameters have physically justified and allow us to simulate the operation of the air motor with acceptable accuracy. The results obtained show the promise of this approach to solving the problem of identifying the pneumatic drives parameters.
