Embodiment 1

[0037] In the traditional scheme, for the design of window sound insulation, it is generally used to design different window samples and organize experimental tests to verify the optimization effect and the final structure, which requires a lot of manpower and material resources, and design and The test period is long, not time-sensitive, and unable to respond quickly to changes in the plan.

[0038] Therefore, the present invention provides a sound insulation design method for a window, the window includes an inner glass and an outer glass arranged at intervals, and there is an air layer between the inner glass and the outer glass, that is to say, the embodiment of the present invention The sound insulation design method presented is mainly for windows with double glazing.

[0039] Specifically, the sound insulation design method includes: step S1, obtaining the sound insulation performance parameters of the inner glass, outer glass, and air layer; step S2, calculating the th...

Embodiment 2

[0062] The present invention also provides a sound insulation design system for windows. The sound insulation design system corresponds to the sound insulation design method involved in Embodiment 1, and the repeated parts will not be described in detail in this embodiment.

[0063] The window that the sound insulation design system provided in this embodiment also includes an inner glass and an outer glass arranged at intervals, and there is an air layer between the inner glass and the outer glass. The sound insulation design system may specifically include: an acquisition module 1 , used to obtain the sound insulation performance parameters of the inner glass, outer glass, and air layer; the calculation module 2, connected to the signal acquisition module 1, is used to receive the sound insulation performance parameters obtained by the acquisition module 1, and is used to obtain the sound insulation performance parameters according to the sound insulation performance The theo...

Abstract

The invention discloses a sound insulation design method for a window and a sound insulation design system for a window. The window comprises inner-layer glass and outer-layer glass which are arranged in a spaced mode, an air layer exists between the inner-layer glass and the outer-layer glass, and the sound insulation design method comprises the steps that: S1, sound insulation performance parameters of the inner-layer glass, the outer-layer glass and the air layer are obtained; S2, the theoretical sound insulation index of the window is calculated according to the sound insulation performance parameters; S3, whether the theoretical sound reduction index reaches a target sound reduction index or not is judged, and if not, the following step S4 is executed; and S4, the sound insulation performance parameters are adjusted, and the step S1 to the step S3 are repeatedly executed. Through adoption of the sound insulation design method, the design of the sound insulation index of the window is mainly conducted through simulation calculation, the design period is short, different design schemes can be fed back in time, the schemes can be conveniently adjusted, high timeliness is achieved, and the design cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of sound insulation design, in particular to a sound insulation design method and a sound insulation design system for windows. Background technique [0002] With the rapid development of rail vehicle technology, the running speed of rail vehicles has been greatly increased, resulting in a significant increase in noise sources outside the vehicle, which seriously affects the comfort of passengers and poses a more severe challenge to the noise control of the vehicle. [0003] Research experience shows that when a rail vehicle is running at high speed, the contribution of the side wall area to the interior noise is obvious, second only to the floor area, and when the rail vehicle is running in a tunnel, the contribution of the side wall area is equivalent to that of the floor area, so , strengthening the sound insulation optimization design of the side wall area is of great significance to improve the noise in...
