3D printing railway fastener damping elastic strip and manufacturing method thereof
The invention discloses a 3D printing railway fastener damping elastic strip and a manufacturing method thereof, an inner cavity is formed in the middle of the 3D printing railway fastener damping elastic strip, the inner cavity is filled with metal powder, and a main body part of the 3D printing railway fastener damping elastic strip is formed through 3D printing. According to the 3D printing railway fastener damping elastic strip, the resonance response amplitude of the elastic strip can be effectively reduced, vibration attenuation is fast, resonance fatigue failure of the elastic strip is avoided, and large-scale and automatic manufacturing can be achieved.
本发明公开了一种3D打印铁路扣件阻尼弹条及其制造方法，该3D打印铁路扣件阻尼弹条的中部形成有内腔，所述内腔内填充有金属粉末，所述3D打印铁路扣件阻尼弹条的主体部分通过3D打印成型。该3D打印铁路扣件阻尼弹条可以有效降低弹条共振响应幅值，振动衰减快，避免其共振疲劳失效，并可以规模化、自动化制造。
