Modeling of response times of pneumatic valve systems - model accordance with experimental research results
Dragan Knežević
The paper defines
methods of mathematical modeling of response times of pneumatic
blast-controllable valve systems as well as methods of evaluating the model
accordance with experimental research results. The analytical
expressions of characteristic partial correlation coefficients and multiple
correlation coefficients have been defined for qualitative model evaluation. A
program has been realized for finding out a model of valve response time and for
qualitative model evaluation. The application of described methods has been
illustrated by defining response times of the blast-controlable valve of a
mechana pneumatic system, controlability being dependent on working and
geometric characteristics of valves, model accordance evaluation and
experimental research results. The valves system response time models are
defined. The level of agreement between the model obtained and experimental
results is also estimated.
Key words: pneumatic valve, response time, algorithm, mathematical modeling, model, correlation coefficient, model evaluation.
