The approach to physical modeling of gas-dynamic drive testing in laboratory stand was considered. Similarity analysis was performed; similarity criterions and modeling scales were obtained. The physical model design task was considered with full-scale gas change of full-scale gas for preheated air. The variant of laboratory stand parameters correction was calculated. The method of drive statistical tests was designed with estimate of operation speed for response time at dry friction random character in mechanics. Regression model was constructed.
Рассмотрен подход к физическому моделированию испытаний газодинамического привода в лабораторном стенде. Выполнен анализ подобия и получены критерии подобия и масштабы моделирования. Дана задача проектирования физической модели привода с заменой натурного порохового газа подогретым воздухом. Рассчитан вариант коррекции параметров стенда. Разработана методика статистических испытаний привода с оценкой быстродействия по времени срабатывания при учете случайного характера сухого трения. Построена регрессионная модель критерия.
