1) track settlement
轨道下沉
1.
In order to comprehend the occurring and growing mechanism of track settlement,ballast bed settlement was regarded as study object,and the effects of transportation conditions and track structure parameters on ballast settlement were analyzed by using simulation analysis program based on vehicle-track coupling dynamics and track settlement laws.
为理解轨道下沉变形产生与发展机理及主要影响参数,以道床下沉为例,运用车辆-轨道耦合动力学理论和轨道下沉变形法则,借助已开发的仿真分析程序,分析了运营条件与轨道结构参数对道床下沉变形的影响。
2) Tunnel under railway
轨下隧道
4) sunken track
低下轨道
5) glide trajectory
下滑轨道
6) sinkage trajectory
下沉弹道
1.
The sinking process of the separated carrier from submarine-launched missile is a complex kinetic process,the main influence on the distribution of sinkage trajectory is the distribution of the initial kinematic parameters.
在考虑了海流及波浪影响的情况下,建立了基于Matlab/Simulink的潜射导弹运载器下沉过程的动力学模型;进而应用数理统计中的正交试验方法对运载器初始运动学参数对其下沉弹道的散布影响程度进行了分析,找出了对于特定的弹道指标不同的初始运动学参数对其影响的主次顺序,为工程上解决运载器砸艇问题提供了可靠的依据。
