The invention relates to a high-performance railway wagon swing bolster structure and a bogie, the high-performance railway wagon swing bolster structure comprises a swing bolster body, the middle section of the swing bolster body is provided with a plurality of first channels arranged in the width direction of the swing bolster body, and the first channels are filled with first vibration attenuation units; the two ends of the swing bolster body are each provided with a second channel arranged in the width direction of the swing bolster body, and the second channels are filled with second vibration attenuation units. By arranging the first vibration attenuation unit and the second vibration attenuation unit, high-frequency vibration can be effectively attenuated, low-frequency resonance interference can be inhibited, the defect that the main frequency amplitude of an existing waveform is suddenly high is overcome, therefore, the problems of endpoint oscillation and aliasing of the areawhere the swing bolster is located can be solved, and finally the service life of the swing bolster can be effectively prolonged.

本发明涉及高性能铁路货车摇枕结构及转向架，所述高性能铁路货车摇枕结构包括摇枕本体，摇枕本体的中段设置有多个沿着摇枕本体宽度方向设置的第一通道，所述第一通道处填充有第一振动衰减单元；所述摇枕本体的两端分别设置有沿着摇枕本体宽度方向设置的第二通道，所述第二通道处填充有第二振动衰减单元。本发明通过设置第一振动衰减单元和第二振动衰减单元，能够有效衰减高频振动、抑制低频共振干扰，解决现有波形的主频幅值突高的缺陷，从而有利于消除摇枕所在区域的端点振荡、混叠问题，最终能够有效提高摇枕的使用寿命。
