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.

Embodiment Construction

[0018] Such as figure 1 As shown, a generalized comfort detection system includes a human body model and a sensor installed on the human body model, a data acquisition unit that collects sensor data, and a wireless transmission unit. The sensor, data acquisition unit, and wireless transmission unit are connected in sequence. The generalized comfort The degree detection system and the portable analyzer constitute a detection platform. After the data acquisition unit collects the data, it is wirelessly transmitted to the portable analyzer through the wireless transmission unit, and the generalized comfort degree is calculated in real time and displayed on the display screen.

[0019] Sensors include vibration sensors, illuminance sensors, sound level sensors, air pressure sensors, temperature sensors, humidity sensors and gas concentration sensors. The illuminance sensor is installed at the eye position of the human model to detect the illuminance inside the car. The sound level dev...

Abstract

The invention relates to testing equipment for testing the generalized comfort of train rides, in particular a generalized comfort detection system, comprising a human body model, sensors installed on the human body model, a data acquisition unit and a wireless transmission unit for collecting sensor data, sensors, The data acquisition unit and the wireless transmission unit are connected in sequence. This generalized comfort detection system takes the main physical factors that affect the generalized comfort as the test object, simulates the comprehensive induction of various parameters by passengers in the specific position of the train, and evaluates the generalized comfort of high-speed trains. , The detection system adopts a wireless data transmission scheme, which reduces the cost of car body modification and wiring workload.

Description

Technical field [0001] The invention relates to a test device for testing the ride comfort, in particular to a generalized comfort 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 will inevitably become one of the focuses of high-speed train improvement. However, it is far from enough to evaluate comfort by relying only on the current vibration measurement comfort method of railways, and it is also difficult to guarantee the comfort of passengers on the train, and it does not meet the requirements of the current coordinated development of railway passenger transportation safety, high speed, and comfort. Therefore, to improve the comfort of high-speed trains, the above requirements cannot be met by only considering the impact of train vibration. Other factors affecting the comfort of tra...
