Embodiment 1

[0040]This embodiment is an application example of a high ultrasound speed. The specific situation is as follows: The newly modified test process requires T = 0 seconds to turn on the throttle valve; T = 1 second, turn on the main valve; T = 3 seconds, perform the valve bit judgment, if the main valve is fully turned on, and the adjustment valve is opened The degree is greater than 60%, then transfer to the liquid oxygen filling process, otherwise transfer to the emergency stop operation process. The wind tunnel control program is currently in the actual state, the main valve and throttling are closed. According to the data given by the valve manufacturer, the throttle valve is fully open for 4 seconds, and the valve bit is increased by time, and the main valve open valve time is 1.85 seconds. The simulation process of the test process includes the following steps:

[0041]a. The operator sets the throttle valve through the upper computer to 4 seconds, and the main valve opening valve ...

Abstract

The invention discloses a wind tunnel test process verification method integrating practical operation and simulation. The wind tunnel test process verification method is based on the wind tunnel control program. The wind tunnel control program is provided with a corresponding control module for each field device, and each control module is provided with a mode switching interface, a set of actual input and output interfaces, a Set of program control intermediate interface and a simulation sub-module. The wind tunnel test process verification method can directly simulate the action of the wind tunnel equipment in the wind tunnel control program, test the sequence and logical interlock relationship in the wind tunnel test process, and complete the relevant verification work of the test process safely, effectively and quickly. The wind tunnel test process verification method does not require additional software and hardware resources, and can be implemented in any general-purpose controller and supporting development software.

Description

Technical field[0001]This method belongs to the field of wind tunnel test technology, which involves a wind tunnel test process verification method for practical and simulation integration.Background technique[0002]High ultrasound speed high-temperature wind tunnel safety problem, wind tunnel test involves a variety of hazardous media such as flammable, explosive, strong oxidation, deep cold, equipment is in high pressure, strong vibration, high temperature and hot and cold alternative environment, numerous hazardous factors. The time and economic cost of the wind tunnel test: before the wind tunnel test, the high ultrasound speed high temperature wind hole is inspected on hundreds of equipment on hundreds of equipment. The preparation process takes average 4 ~ 8 hours; high ultrasound speed high temperature wind hole reaches 3 The meter level, the flow rate is a hundred kilograms per second, and the cost of implantation is more than 10,000 yuan. The wind tunnel test process is comp...
