braking contact 中文意思是什麼
braking contact
解釋
制動觸點-
As a part of the civil 863 plans, two multiple - contact models for two kinds of braking system are built in the paper, in which contact fields are described as coons surfaces, initial velocity is programmed in fortran. the thermal - mechanical coupling braking processes are simulated for the first time by msc. marc, the general - used nonlinear fem software. time distributions of the velocity, the stress and the temperature of the components under various initial velocity and brake force are obtained, which offer theoretic gist to study the life of the wheel, the disc and so on
作為國家行業863重大課題《鐵路機車車輛虛擬樣機系統》的一部分，本文在研究接觸問題和熱?機耦合問題數值方法的基礎上，採用國際上通用的非線性有限元分析軟體msc . marc建立了踏面制動和盤形制動主要部件的多體接觸計算模型，其中用解析方法描述，即用nurb曲線、高斯曲面來描述接觸區域，用fortran語言編寫定義初速度的用戶子程序，首次對兩種制動過程熱?機耦合進行了數值模擬，定量給出了主要制動部件在不同初速度、不同制動力下各個時刻的速度、應力和溫度的變化規律，為研究車輪、閘瓦以及制動盤壽命提供了理論依據。 -
Towing vehicle, trailer and semi - trailer pneumatic braking systems - " contact " type couplings
牽引車輛掛車和半掛車氣動制動系統. 「接觸」式連接器 -
It sounds counter intuitive, but an important thing to remember on descends is to relax, try to be fluent with your movements, if you are relaxed, with your knees and arms bend, you help the tires stay in contact with the ground for more control of braking traction
這聽起來跟你的直覺相反，可是有個很重要的一點是下坡時記得要放鬆，試著流暢的動作，如果你放鬆騎而且彎曲你的膝蓋和手臂，輪胎會保持接觸地面讓你更好控制煞車的抓力。 -
Thereinto, the controlling method is altered into air cylinder control installed on two sides of transmission shaft, steel structure platform and rushing - board brake. these alterations enable the equipment to be more sensitive and reliable for controlling. steel structure platform makes noise giving off when equipment operates greatly decrease and rushing board brake prolongs the service life of friction belt because it owns large braking area which can contact flywheel and gain large moment and then do little harm to friction belt
二j53 - 630b型在j53 - 630a型的基礎上作了改進，其中操縱方式改為裝在傳動軸兩端的氣缸操縱，剛結構式平臺，推板式剎車這樣使設備的操縱更靈敏可靠剛結構式平臺使設備工作時噪音大大降低，推板式剎車由於剎車板剎車面積大與飛輪的接觸均勻，所以剎車力矩大同時對摩擦帶的損傷小，延長摩擦帶的使用壽命，推板式剎車平行調整故調整方便。
