The invention relates to the technical field of train spoilers, in particular to a high-speed train cavity-like area spoiler structure which is installed between two train bodies and located in a cavity-like area formed by two vertically-distributed train apron boards installed at the ends of the train bodies. Airflow generated on the two sides of the cavity-like area in the advancing process is disturbed, and aerodynamic noise of related areas of a steward room is reduced; the high-speed train cavity area turbulent flow structure has the beneficial effects that the turbulent flow structure is composed of the two sets of turbulent flow plates, and each set of turbulent flow plates comprises the two L-shaped turbulent flow plates fixed to the ends of the two train apron boards respectively. By means of the design, the spoiler can effectively disturb airflow generated on the two sides of the cavity-like area in the advancing process, and therefore aerodynamic noise is reduced.
本发明涉及列车扰流板技术领域,具体为一种高速列车类腔体区域扰流结构,安装在两个列车车体之间,且扰流结构处于列车车体端部安装的两组上下分布的两组列车裙板之间构成的类腔体区域,扰流结构在列车车体运行过程中,对行进过程中在类腔体区域两侧产生的气流进行扰动,降低乘务员室相关区域的气动噪声;有益效果为:本发明提出的高速列车类腔体区域扰流结构,扰流结构由两组扰流板组成,每组扰流板包括两个分别固定在两个列车裙板端部的“L”形扰流板。这种设计使得扰流板能够有效地对行进过程中在类腔体区域两侧产生的气流进行扰动,从而降低气动噪声。
