高速电梯井道气动力优化设计方案探讨

Demonstration of the Optimum Design of Shaft Aerodynamic Scheme for High-speed Elevator

对目前即将进行实验的8.00m/s超高速电梯模型的气动力和气动噪声进行数值模拟,对电梯的安全性和舒适性进行了分析评估,并在不改变轿厢尺寸和井道尺寸的前提下提出了两种改进方案。计算结果表明,在井道侧壁开通风孔可以明显减小气动阻力和气动噪声,也可以很好地改善由于侧向力脉动引起的机械噪声。

In this paper,numerical simulations have been performed to obtain the aerodynamic forces and aero-acoustics of the ultra-high-speed elevator with the velocity of 8.00 m/s,on which experiment is about to be run.The safety and comfortability are analyzed and assessed,and two improvements are proposed.The numerical results indicate that ventilation holes on one/both side of the well will reduce aerodynamic forces and areo-acoustics obviously,so is the vibration of the lift force so that the mechanical noise is reduced as well.
