Based on the sha lo wan profiler data at 0740utc , the vertical shear at around 1 , 100 ft was close to 8 kt per 100 ft . although this was lower than the 8 kt per 100 ft which has been used in the windshear warning system at the old kai tak airport , the increase in head wind was nonetheless significant due to the steep climb angle 根據沙螺灣的氣流剖析儀在0740utc錄得的資料顯示,在約1 , 100尺的垂直切變接近每百尺每小時8海里。雖然此切變低于以往啟德機場的風切變警報系統所用的每百尺每小時8海里,但因為陡峭的爬升角度,令到逆風的增加變得顯著。

This article takes the lagrange equation as the principle , establishes mathematics modeling to the inertia brake vibration when it brakes , then simulates it with matlab . this paper educed the relation equations between , which are the inertia brake ' s friction coefficient of the brake ring and the friction disk , the mean radius , the braking force , rotation inertia of the driving top and the spline shaft , spiral climbing angle of the brake ' s concave - convex helicoid , the mean effort radius of the concave - convex helicoid , elasticity coefficient of the spring , quality of the driving top and the spline shaft , rotations inertia of the brake ' s rotation part besides the driving top and the spline shaft , suppresses sleeve . provides the theory basis for the inertia brake structure optimization 本文以拉格朗日方程為理論基礎,對慣性制動器在制動時的振動進行數學建模,然后用matlab對其進行仿真,得出了慣性制動器在制動時振動角頻率分別與制動環和摩擦片之間的摩擦系數、制動力的平均半徑、主動頂和花鍵軸的轉動慣量、慣性制動器的凹凸螺旋面的螺旋升角、凹凸螺旋面平均作用力的半徑、彈簧的彈性系數、主動頂和花鍵軸的質量、慣性制動器除主動頂和花鍵軸外其他部分的轉動慣量和、頂壓套的質量等慣性制動器各零部件的物理參數之間的關系,為慣性制動器的結構優化提供了理論依據。
