specific Embodiment approach 1

[0010] Specific implementation mode one: combine figure 1 Describe this embodiment, the profile plate of this embodiment includes a horizontal upper plate 1 and a horizontal lower plate 2, and the profile plate also includes a plurality of cross-shaped components 3, and each cross-shaped component 3 is composed of a vertical plate 3-1 and a horizontal set The noise-reducing and vibration-reducing plate 3-2 is composed of the vertical plate 3-1 and the horizontally arranged noise-reducing and vibration-reducing plate 3-2. Between the horizontal upper plate 1 and the horizontal lower plate 2, the horizontal upper plate 1, the horizontal lower plate 2 and a plurality of cross-shaped components 3 are integrated.

specific Embodiment approach 2

[0011] Specific implementation mode two: combination figure 1 To illustrate this embodiment, the thickness of each rectangular vibration and noise reduction plate 4 in this embodiment is 0.02m. This structure can improve the effect of vibration and noise reduction under the premise of ensuring the same quality. Other components and connections are the same as those in the first embodiment.

Abstract

The invention discloses a profile plate for a train carriage, and relates to a profile plate. Aiming at the problem that the traditional train profile plate cannot play a role in reducing internal vibration and noise of the carriage, the invention adopts the following schemes that: 1, each cross assembly consists of a vertical plate and a noise and vibration reduction plate arranged horizontally, the vertical plate and the noise and vibration reduction plate arranged horizontally are manufactured into a whole, and a horizontal upper plate, a horizontal lower plate and a plurality of cross assemblies are manufactured into a whole; 2, two ends of the horizontal noise and vibration reduction plate are respectively provided with a lug boss; 3, a rectangular vibration and noise reduction plate is vertically arranged on the outer surface of a first middle plate and manufactured into a whole with the first middle plate, and a rectangular vibration and noise reduction plate is vertically arranged on the inner surface of a second middle plate and manufactured into a whole with the second middle plate; and 4, the rectangular vibration and noise reduction plates in the scheme 3 are replaced by using T-shaped vibration and noise reduction plates. The profile plate is used for constructing the train carriage.

Description

technical field [0001] The invention relates to a profiled plate. Background technique [0002] The train compartment is composed of train profile panels. The traditional train profile panels play the role of forming and supporting the compartment structure, but cannot reduce the vibration and noise inside the compartment, so they must be pasted on the interior of the compartment profile panels. The damping layer is used to reduce the vibration and noise inside the car, but the damping sheet has many disadvantages: high technical requirements for production and pasting, high production costs, easy aging, poor suppression of high-frequency vibration and noise, and involving a variety of toxic chemicals Substances are likely to cause environmental pollution, etc. Contents of the invention [0003] The object of the present invention is to provide a profile plate for train carriages to solve the problem that the current traditional train profile plates can only reduce the vi...
