【摘要】：液体平衡环是波轮洗衣机减振的重要部件,针对波轮洗衣机脱水过程中的振动问题,通过优化液体平衡环结构参数的方法改善其减振性能。利用模拟软件FLUENT 14.5对平衡环内部流场进行数值模拟,探究了凸筋数量、凸筋开孔尺寸、环道宽度比、容积比等对平衡环减振性能的影响规律。模拟结果表明,凸筋数量增加会提高平衡环启动阶段减振性能,但是稳定阶段反之;凸筋开孔有助于提高其减振性能和使用寿命;双环道平衡环在宽度比为50%时减振性能最佳;容积比为55%时平衡环减振性能最好。
[Abstract]:The liquid balance ring is an important part of the wave wheel washing machine to reduce the vibration, aiming at the vibration problem of the wave wheel washing machine during dehydration, By optimizing the structural parameters of the liquid balance ring, the vibration absorption performance is improved. The numerical simulation of the flow field in the equilibrium ring is carried out by using the simulation software FLUENT 14. 5, and the number of the convex ribs, the size of the opening hole of the convex rib, and the ratio of the width of the ring to the channel are investigated. The effect of volume ratio on the vibration absorption performance of the balancing ring. The simulation results show that the increase of the number of convex bars will improve the vibration absorption performance of the equilibrium ring at the starting stage, but the stability phase will be reversed, and the opening of the convex rib will help to improve the vibration absorption performance and service life of the ring. When the width ratio is 50 and the volume ratio is 55, the damping performance of the double loop balance ring is the best.
