The invention discloses a noise elimination structure for an air supply duct of a railway vehicle, which comprises a first air duct and a second air duct, and is characterized in that a noise elimination device is arranged in the second air duct, and an air inducing device is arranged in the first air duct; the noise elimination device comprises a sponge body and a honeycomb box, the sponge body is located between the honeycomb box and the second air duct, and the two sides of the sponge body are connected with the honeycomb box and the second air duct respectively; the air inducing device comprises a fan and a driving motor, and two vertical rods are arranged at the top and the bottom of the first air channel. Through the arrangement of the sponge body and the honeycomb box, the sponge body can well prevent external sound from being conducted through the second air duct, the box body of the honeycomb structure is provided with a plurality of equilateral hexagonal structures, the wind conduction rate can be reduced, refraction of wind when the wind passes through the second air duct is increased, and the wind conduction efficiency is improved. The sound attenuation can be well carried out when the automobile enters the interior of the automobile through the second air duct.
本发明公开了一种轨道车辆送风道消声结构,包括第一风道和第二风道,其特征在于,所述第二风道的内部设置有消音装置,所述第一风道的内部设置有引风装置;所述消音装置包括有海绵体和蜂巢箱,所述海绵体位于蜂巢箱和第二风道之间,且海绵体的两侧分别与蜂巢箱和第二风道连接;所述引风装置包括有风扇和驱动电机,所述第一风道的顶部和底部设置有两个竖杆。本发明通过设置的海绵体和蜂巢箱,海绵体可以很好的阻隔外界的声音通过第二风道的传导,蜂窝结构的箱体具有众多的等边六角形结构,能够减小风传导的速率,增大风在通过第二风道时的折射,能够很好的在通过第二风道进入车辆内部时进行很好的消音。
