The result shows that the permitted maximum normal berthing velocity of the ship is related to the displacement of the ship, the performance of the rubber fender, the maximum strength of the offload platform, and it is proportional to the inverse of displacement. 研究结果表明,船舶允许的最大靠泊法向速度与船舶的排水量成反比,并且与橡胶护舷性能和卸载平台的最大承载能力有关。
The mathematical expressions of maximum and minimum velocity ratio that the whole powertrain system requires are defined through the analysis of driving cycle and dynamic performance of sleigh car and the research of external characteristic curve of engine. 通过对雪橇车行驶工况及动力性分析以及其发动机外特性试验曲线研究,确定整个传动系统所需的最大和最小速比的数学表达式。
