The invention relates to the technical field of vacuum pipeline traffic, and discloses a vibration and noise reduction train body and a vacuum pipeline train. The vehicle body comprises an inner cabin body, an outer cabin body, a shock absorber and a vacuum layer, the vacuum layer is arranged between the inner cabin body and the outer cabin body, the inner cabin body and the outer cabin body are connected through the shock absorber, the inner cabin body comprises an inner cabin skin and an inner cabin framework, the inner cabin skin is connected with the inner cabin framework, and the inner cabin skin is connected with the inner cabin framework. The outer cabin body comprises an outer cabin skin and an outer cabin framework, and the outer cabin skin is connected with the outer cabin framework. Therefore, after the outer cabin body is damaged, the independent inner cabin body still keeps enough strength and sealing performance, and the safety of passengers in the cabin can be effectively kept. Moreover, a vacuum layer is arranged between the inner cabin body and the outer cabin body, air sound transmission between the outer cabin body and the inner cabin body can be isolated, the damper adopts an active control mode, damping of the damper is adjusted, structural sound can be effectively absorbed, meanwhile, vibration transmission paths are reduced, and the riding comfort is effectively improved.

    本发明涉及真空管道交通技术领域,公开了一种减振降噪车体及真空管道列车。其中,该车体包括内舱体、外舱体、减振器和真空层,所述真空层设置在所述内舱体和所述外舱体之间,且所述内舱体和所述外舱体通过所述减振器连接,所述内舱体包括内舱蒙皮和内舱骨架,所述内舱蒙皮与所述内舱骨架连接,所述外舱体包括外舱蒙皮和外舱骨架,所述外舱蒙皮与所述外舱骨架连接。由此,在外舱体出现损伤后,独立的内舱体依然保持足够的强度及密封性,可有效保持舱内乘客安全。并且,内、外舱体之间为真空层,可以隔绝外舱‑内舱空气传声,减振器采用主动控制方式,对减振器阻尼进行调节,可以有效的吸收结构声,同时减少振动传递路径,有效地提高乘坐舒适性。
