基于三元流理论的电磁涡流刹车内部管道结构仿真分析
|
摘要
基于三元流理论应用ANSYS软件对不同结构条件下管道的流动特征进行仿真分析。结果表明:冷却油进油腔道的中心线与循环冷却油管的中心线相交且相互垂直时,粒子的运动状态相对平稳,对电磁涡流刹车本体的机械振动影响较小。
Basing on 3-D flow theory,applying ANSYS to simulate and analyze the flow characteristics of pipelines under different structural conditions was implemented to show that,when the central line of the cooling oil's inlet passage and that of the circulating cooling oil pipe are intersect and perpendicular to each other,the state of motion of particles becomes relatively smooth and steady and it influences less the mechanical vibration of the electromagnetic eddy current brake.
