Pure transparent noise reduction car window
The invention discloses a pure transparent noise reduction vehicle window. The vehicle window is formed by periodic array expansion of transparent functional units. A plurality of pure transparent materials are compounded to form the local resonance unit, so that the transparent function and the vibration reduction and sound insulation function can be realized at the same time. Structural parameters can be adjusted according to needs, so that the target vibration reduction frequency falls into the designed band gap frequency range. In addition, the clamping plates on the two sides are fixed, the thickness is increased, and the low-rigidity transparent elastic body is introduced to serve as an elastic part, so that the defect that a traditional thin plate type superstructure strongly depends on pretension of the plate can be overcome, the design work stability is improved, and the low-frequency-band sound insulation performance can be effectively improved. In conclusion, the pure transparent noise reduction car window can achieve excellent low-frequency sound insulation and vibration reduction effects on the premise of guaranteeing the lighting capacity, and compared with a traditional car window, the pure transparent noise reduction car window is better in low-frequency vibration reduction and sound insulation capacity, lighter in structure and capable of being widely applied to vibration reduction and noise reduction of car window structures of various carrying tools.
本发明公开了一种纯透明降噪车窗，该车窗是由透明功能单元周期性阵列拓展而成。通过采用多种纯透明材料复合成局域共振单元，可以实现透明与减振隔声功能兼顾的作用。根据需要可调整结构参数，使得目标减振频率落入所设计的带隙频率范围内。此外，通过固定两侧夹板并增加厚度以及引入低刚度透明弹性体充当弹性部分，不仅可以克服传统薄板型超结构强烈依赖于板的预张力的不足，提高设计工作稳定性，还可以有效提高低频段隔声性能。综上，这种纯透明降噪车窗能够在保证采光能力的前提下，同时达到优异的低频隔声和减振的效果，与传统车窗相比，低频减振与隔声能力更出色，结构更轻，可广泛应用于各类运载工具的车窗结构的减振降噪中。
