Portable generalized comfort testing system

Abstract

The invention relates to a test device for testing the generalized comfort of train rides, in particular to a portable generalized comfort detection system, including a detection system and a portable analyzer. The detection system includes a human body model, sensors installed on the human body model, and acquisition sensors The data acquisition unit and the wireless transmission unit of the data, the sensor, the data acquisition unit and the wireless transmission unit are connected in sequence, the data acquisition unit collects the data and transmits it to the portable analyzer wirelessly through the wireless transmission unit. The invention takes the main physical factors affecting the generalized comfort as the test object, simulates the comprehensive induction of passengers on various parameters at the specific position of the train, and calculates the generalized comfort of the train in real time. According to the fully enclosed feature of the high-speed EMU, the detection system adopts wireless data The transmission scheme reduces the cost of vehicle body modification and the workload of wiring.

Description

technical field [0001] The invention relates to testing equipment for testing the generalized comfort degree of train riding, in particular to a portable generalized comfort degree detection system. Background technique [0002] With the rapid development of high-speed railways, the comfort of high-speed railways has increasingly become the focus of people's attention. Improving and improving the comfort of high-speed EMUs must also become one of the focuses of high-speed train improvement. However, it is far from enough to rely on the current railway vibration measurement comfort method to evaluate the comfort, and it is difficult to ensure the comfort of passengers, which does not meet the current requirements of the coordinated development of railway passenger transportation safety, high speed, and comfort. Therefore, in order to improve the comfort of high-speed trains, it is impossible to meet the above requirements only by considering the impact of train vibration. It ...

Problems solved by technology

[0003] Foreign research on train comfort is mainly based on its vibration acceleration. Western developed countries began to test train ride comfort through tests as early as the 1950s and 1960s, and established a relatively complete comfort evaluation based on these test data. standards, but there is no uniform standard in the world for the comfort evaluation standards of railway rolling stock.
