The correlation coefficient of the example of table 6
Then, using the Sobol methods in step 4, the optimization order for standard deviation and each parameter of maximum is judged,
Such as accompanying drawing 5.As can be observed from the foregoing, for standard deviation, need increase contact line tension, reduce contact line line density
With load rope tensility, increase carrier cable line density；For maximum, need increase contact line tension, reduce load rope tensility and
Contact line line density, increase carrier cable line density, and propose the prioritization scheme such as subordinate list 7；
The policy scheme of the example of table 7
| Optimization step sequence number | Change parameter | Parameter designing |
| 0 | Nothing | Tc=21kN, Tj=27kN, mc=1.08kg/m, mj=1.08kg/m. |
| 1 | Tj | Tc=21kN, Tj=34kN, mc=1.08kg/m, mj=1.08kg/m. |
| 2 | Tj、mj | Tc=21kN, Tj=34kN, mc=1.08kg/m, mj=0.758kg/m. |
| 3 | Tj、mj、Tc | Tc=14kN, Tj=34kN, mc=1.08kg/m, mj=0.758kg/m. |
As can be drawn from Table 7 such as the actual effect figure in Fig. 6 and 7, it can be seen that by the way that catenary's parameterses are altered in steps
Afterwards, the standard deviation of contact pressure is reduced to 40N or so；The meansigma methodss of contact pressure are in the range of 70～110N；Contact pressure
Maximum is reduced to below 250N；Ratio of contact loss is reduced to less than 1%.As can be seen that the later contact pressure of optimization respectively refers to
Mark, in the prescribed limit of EN50318 standards and TB10621-2014 standards.
