Problems solved by technology

[0003] However, these methods only use the vibration acceleration of the car body as the basis for evaluating the ride comfort, which is difficult to reflect the real feelings of the passengers themselves, and cannot accurately evaluate the comfort of the passengers. Require

Embodiment 1

[0082] The implementation of the present invention provides a high-speed railway passenger comfort evaluation method, such as figure 1 As shown, the method includes:

[0083] Step S1: Establish a passenger-vehicle-bridge coupled vibration model, where the passenger-vehicle-bridge coupled vibration model is composed of a vehicle model, a passenger model, and a bridge model. The vehicle model, the passenger model, and the bridge model are described in detail below.

[0084] Vehicle model

[0085] The vehicle model includes several carriages. Each carriage includes a car body, a front bogie, a rear bogie and several wheel sets. The car body, front bogie and rear bogie all have head nodding, head shaking, side roll, hesitation, and yaw 5 There are three degrees of freedom, and the wheelset has three degrees of freedom: yaw, roll, and sink.

[0086] Locomotives and multiple passenger cars are combined to form a railway vehicle model. Each car is a multi-degree-of-freedom vibration system...

Embodiment 2

[0218] The embodiment of the present invention provides a high-speed railway passenger comfort evaluation device corresponding to the high-speed railway passenger comfort evaluation method described in Embodiment 1, such as Figure 8 As shown, the device includes:

[0219] Model building module 1 is used to build a passenger-vehicle-bridge coupled vibration model, where:

[0220] The vehicle model includes several carriages. Each carriage includes a car body, a front bogie, a rear bogie and several wheel sets. The car body, front bogie and rear bogie all have head nodding, head shaking, side roll, hesitation, and yaw 5 There are three degrees of freedom, and the wheelset has three degrees of freedom: yaw, roll, and sink.

[0221] The bridge model is a continuous steel truss arch bridge finite element model.

[0222] The passenger model regards each passenger as a rigid body, and each passenger has six degrees of freedom: roll, sink, roll, shake, nod, and longitudinal displacement.

Embodiment 3

[0251] The method described in the foregoing embodiment provided in this specification can implement business logic through a computer program and record it on a storage medium, and the storage medium can be read and executed by a computer to achieve the effects of the solution described in Embodiment 1 of this specification. Therefore, the present invention also provides a computer-readable storage medium for high-speed railway passenger comfort evaluation corresponding to the high-speed railway passenger comfort evaluation method of Embodiment 1, including a memory for storing processor-executable instructions. When executed by the processor, the steps of the high-speed railway passenger comfort evaluation method including the first embodiment are realized.

[0252] The storage medium may include a physical device for storing information, and usually the information is digitized and then stored in an electric, magnetic, or optical medium. The storage medium may include: devices...

Abstract

The invention discloses a high-speed railway passenger comfort evaluation method and device, a computer readable storage medium and equipment, and belongs to the field of high-speed railways. The method comprises: establishing a passenger-vehicle-bridge coupling vibration model, inputting passenger, vehicle, bridge and wind load parameters into the model, calculating initial conditions, obtainingdynamic response data of passengers, vehicles and bridges through solving and outputting, and evaluating the comfort degree of passengers according to the dynamic response data of the passengers. According to the method, the passenger dynamic model is added, the passenger-vehicle-bridge coupling vibration model is designed, the comfort degree is evaluated by solving the dynamic response data of the passenger and using the vibration data of the passenger, and the evaluation method can better reflect the real feeling of the passenger.

Description

Technical field [0001] The present invention relates to the field of high-speed railways, in particular to a method, device, computer-readable storage medium and equipment for evaluating the comfort of high-speed railway passengers. Background technique [0002] The rapid development of high-speed railways in my country has gradually increased the proportion of viaducts and large-span bridges in the line. With the increase in train speed and the continuous improvement of people's living standards, the problem of ride comfort has become increasingly obvious and has gradually become the focus of the railway sector. Domestic and foreign research on the comfort of railway transportation lines is mainly based on the dynamic interaction of vehicle and bridge, and some other load forms such as wind, earthquake, ship collision, etc. are considered, so as to obtain relevant parameters such as vehicle floor vibration acceleration, and then pass ISO2631 Standards, Sperling indicators or ot...
