ballast resistance

基本解釋

Pivoting on a pin inside the hull, it swings down to provide ballast and resistance against sideways motion of the boat caused by the wind blowing from one side.
它圍繞船底的一個釘子旋轉(zhuǎn)，放下時提供壓載力，以抵抗由于單側(cè)風(fēng)導(dǎo)致的船只側(cè)向擺動。
By many years experiences, controlling ballast resistance and excessive compressive temperature force of the rail is recognized as the only means to overcome the track buckling.
多年來認為控制道床阻力及鋼軌內(nèi)的溫度力是防止脹軌跑道的主要辦法。
Research methods:A track-frame model has been developed, which includes rails, pads, sleepers and ballast resistance, and the finite element program has been exploited using numerical formulation.
研究方法：建立了包含鋼軌、扣件、軌枕和道床阻力為一體的軌道框架模型，推導(dǎo)了相應(yīng)的數(shù)值計算公式并編制了有限元程序。

道床阻力
The FEM model is a track framework that includes rails, ties, rail fastenings and ballast resistances as a whole system. It can consider the nonlinear deformation of rail, ballast nonlinear resistance and rail fastenings nonlinear resistance moment.
該模型是包含鋼軌、扣件、軌枕和道床阻力為一體的軌道框架及考慮了鋼軌非線性變形、道床非線性阻力和扣件非線性阻矩的分析無縫線路軌道穩(wěn)定性較全面的一個模型。
