With the upgrade and iteration of trains and the increase in design speed, the problems of vibration and noise inside the car have also become prominent. The vibration and noise of the car will affect the ride comfort of the train. Scientific and effective in-car noise control technology has become an important supporting measure for train speed-up.

[0003] Composite sound insulation profiles with foam as the main body and particle damping or other viscoelastic damping have shown good results in train noise control. They have thermal insulation, fire prevention, sound insulation and vibration reduction properties and can be used on the floor, roof and wall panels of the carriage. Figure 1 As shown, the train carriage is made of aluminum alloy profiles with a triangular cavity inside. To ensure the effect, the sound insulation profile 2 should be tightly fitted to the carriage panel 1 during installation. Therefore, the cross-sectional size of the sound insulation profile 2 should be larger than the cross-sectional size of the cavity 11 in the carriage panel 1 during design, and the length direction is designed to be different lengths according to the carriage, and is installed in sections, which increases the difficulty of installation.
