QUANTITATIVE EVALUATION METHOD FOR OPERATION CONTROL OF RAILROAD TRAIN AT THE TIME OF STRONG WIND

摘要

PROBLEM TO BE SOLVED: To provide a quantative evaluation method for the operation control of a railroad train at the time of strong wind to evaluate the safety of the operation control of a railroad car quantitatively at the time of strong wind.;SOLUTION: The safety evaluation method for the operation control of the railroad train at the time of strong wind is configured so that the evaluation index P is determined from the equation according to the figure while the toppling limit wind speed u_c of the railroad car and the operation controlling wind speed are used as parameters, and on the basis of the obtained index P, the safety of the operation control at the time of strong wind is evaluated quantitatively. In the equation, u_r is slow running wind speed, u_s is the inhibiting wind speed, P(U) exhibits an appearance probability density function of the wind at speed u, u_p is the maximum instantaneous wind speed for n minutes, u_f is the maximum instantaneous wind speed for m minutes immediately thereafter, and further Pc signifies the probability of such an occurrence that the toppling limit wind speed u_c is exceeded by the maximum instantaneous wind speed u_f for m minutes immediately after the maximum instantaneous wind speed u_p for n minutes is given, wherein the probability Pc takes two values, P_c1 at normal times free of the speed regulation and P_c2 when the speed regulation takes place.;COPYRIGHT: (C)2007,JPO&INPIT
