Embodiment 1

[0030] Example 1 Construction of a hybrid simulation system

[0031] Such as figure 1 As shown, the high-speed passenger room room temperature humidity and pressure fluctuation hybrid simulation system consists of a control system, a detection system connected to the control system, a vehicle body passenger room, a temperature and humidity adjustment system connected to the car body passenger room, and a pressure regulation system. System Components.

[0032] The detection system is composed of a temperature sensor, a humidity sensor and a pressure sensor located in the passenger compartment of the vehicle body connected with the control system. In this way, relevant parameters in the passenger compartment of the car body can be detected in real time and transmitted to the control system.

[0033] The temperature and humidity adjustment system is composed of imported pneumatic disc valves, air conditioning units, humidity control equipment, air inlet ducts, passenger compa...

Embodiment 2

[0038] Example 2 Construction of a hybrid simulation system

[0039] Such as figure 2 As shown, this embodiment is basically the same as Embodiment 1, the difference is that: the imported electric proportional control valve in the pressure regulating system is connected to the air conditioning unit, humidity control equipment and then into the air duct. Of course, there is no need to arrange a second manual shut-off valve.

Embodiment 3

[0040] Embodiment 3 The use of hybrid simulation system

[0041] Such as image 3 As shown, on the basis of the hybrid simulation system constructed above, the simulation is carried out through the following strategies:

[0042] a. Input the desired simulated temperature, humidity and pressure waves to the computer;

[0043] b. Open the inlet pneumatic disc valve and the outlet pneumatic disc valve;

[0044] c. Adjust the air-conditioning unit, and the computer judges whether the temperature in the passenger compartment of the car body detected by the sensor is the same as the expected value. If it is the same, go to the next step, and if it is different, repeat this step;

[0045] d. Adjust the humidity control equipment, judge by the computer whether the humidity and temperature in the passenger compartment of the car body detected by the sensor are the same as the expected value, if they are the same, go to the next step, if they are different, repeat steps c and d;...

Abstract

The invention discloses a high-speed temperature humidity and pressure fluctuation hybrid simulation system as well as an application method, and the simulation system is composed of a control system, a detection system which is connected with the control system, a car body guest room and a humiture regulating system which is communicated with the car body guest room and a pressure regulating system. The simulation system provided by the invention can simulate and reproduce the possibly existing temperature size, humidity size and different characteristic pressure waves of a high-speed train in actual service. All characteristic sets and comfort relations of three physical parameters are set, and air three parameters in a guest room are influenced on the evaluation criteria on comfortability, which further provides important guide meanings in improving, optimizing and designing the comfortability, material lectotype and the like.

Description

technical field [0001] The invention relates to a simulation system and a use method thereof, in particular to a high-speed vehicle body passenger room temperature humidity and pressure fluctuation mixing simulation system and a use method thereof. Background technique [0002] In recent years, with the rapid development of high-speed rail, the comfort of passengers during high-speed train operation is an important topic following the research on high-speed train operating speed, service reliability, and operational safety. This issue has received great attention and needs to be studied in depth. But in the research process, there are many problems that need to be solved urgently, such as high-speed train comfort simulation test technology, comfort evaluation theory, comfort improvement and optimization technology, etc. The mixed simulation method of temperature, humidity and pressure fluctuation in the high-speed train body is a test system to study the influence of the th...
