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,然後用matlab對其進行模擬,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。
The study shows that the longitudinal component of the pressure force is mainly balanced by the vertical eddy frictional term and the lateral component of the pressure force is mainly balanced by the coriolis force
研究表明:在磨刀門河口動力平衡中,縱向的
主要平衡項為壓力項和垂向渦動
摩擦項,側向的
主要平衡項為側向正壓力項和科氏力項。
Relinquishing his symposiarchal right to the moustache cup of imitation crown derby presented to him by his only daughter, millicent milly, he substituted a cup identical with that of his guest and served extraordinarily to his guest and, in reduced measure, to himself the viscous cream ordinarily reserved for the breakfast of his wife marion molly

No meat was given to the dog even when it refused vegetarian food and it just fasted. three shock treatments later, her puppy developed a very good appetite and now eats almost anything. in addition to its main staple of sweet corn and cheese, it also loves bean sprouts, vegetable stalks, peanuts, pine nuts, guavas, tomatoes, pears, custard apples and other sweet fruits
