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。 -
Based on the three new supposition and the tow new mechanical tools : moment vector and radius vector, the warping theory introduced the analytical method of the rotation of a cross section around a fixed axis, so as to make the space stability of the thin - walled member complanate and one - dimensioned
翹曲理論以三條新的假定和新建立的彎矩矢量和轉角向徑兩大力學工具為基礎，提出了繞定軸轉動的分析方法，使薄壁構件的空間變形平面化、一維化。 -
Walling under the rotation radius of crane boom is prohibited
吊臂旋轉半徑下，禁止人行走。 -
The ultra amusing ultra q remote control sweeps clear the vehicle, 1 to 8 proportions, 8 channels entire directions remote control, when advance backlash on the automobile body work lantern festival glitters, is concurrent music, the careful design remote control conforms to the kinesiology, the unique double throwout lever remote control way, on about remote control two throwout levers each control two powers wheels, slightly cause the vehicle the radius of turn to be more nimble, and marches forward when the vehicle simultaneously opens sweeps the plate to sweep clear and to turn fights controls remotely into the reality, sweeps the plate starts when also can send out delightful music, sweeps the plate also to be able control during rotation rocks, behind in the automobile body work theater box puts has continuously may skid and may open the cover the trash can, the trash can also may take out, turns fights may independently control remotely, the handling room vehicle door may start, the remote control is away from in the city surpasses 30 meters, the spacious area may achieve above 50 meters, holds controls nimbly is convenient, the luminous automobile body paint surface, works first - class, the use industry packs the ni - cd battery to take the power supply, may repeatedly charge 300 above time
超好玩超q的遙控清掃車， 1比8比例， 8通道全方向遙控，前進後退時車身上的工作燈會閃爍，並發出音樂聲，精心設計的遙控器符合人體工學，獨特的雙推桿遙控方式，遙控器上的兩個推桿各控制左右兩個動力輪，使得車的轉彎半徑更小更靈活，並且在車行進時同時開啟掃盤清掃和翻斗遙控成為現實，掃盤啟動時也會發出悅耳的音樂聲，掃盤在轉動的同時還會左右晃動，車身後部的工作廂內放有一直可滑動並可開啟蓋子的垃圾桶，垃圾桶還可以取出，翻斗可以獨立遙控，操作室車門可開，遙控距離在城市中超過30米，空曠地區更可達到50米以上，操控靈活方便，光亮的車身漆面，做工一流，使用工業包裝ni - cd電池組作為動力源，可反復充電300次以上。 -
This is understandable in terms of conservation of angular momentum. as the radius of rotation decreases, the rotational speed will increase accordingly
這現象可用角動量守恆定律來解釋：當旋轉半徑縮短時，旋轉速率就相應加快，以保持角動量不變。
