Embodiment Construction
[0041] Hereinafter, specific embodiments of the present invention will be further described in conjunction with the accompanying drawings.
[0042] The invention provides a method for constructing a typical speed-time driving condition in a rail vehicle area, referring to figure 1 , figure 2 shown, including the following steps:
[0043] (S1) Construct the typical speed-time conditions of all lines in a given area;
[0044] The specific construction method of the typical speed-time working condition of the line is as follows:
[0045] ① Select the appropriate sampling date and number of days to collect the daily speed-time running conditions of the train on a given line, and take the daily speed-time running conditions of the train on the jth sample collection day (abbreviated as the j-th day), and divide each The daily speed-time series S(j) is divided into K sub-segments S'(k,j) according to the stopping and driving state of the train. Namely: Calculate the partial deri...

The invention relates to a typical speed-time driving condition construction method for railway vehicle area. The method comprises steps of constructing typical speed-time conditions for all lines ina given area; then multiplexing the typical speed-time conditions of all lines into the initial speed-time driving conditions for a given area, solving the characteristic value of the speed-time driving conditionof the initial area and the characteristic value of each sub-segment; carrying out normalization deviation calculation on the characteristic value of the sub-segment included in the initial speed-time driving condition and the characteristic value of the regional initial speed-time driving condition respectively and selecting the sub-segments whose characteristic value deviation is less than the set value from the normalized deviation and multiplexing the chatacteristic values to constitute the typical speed-time condition of the area. The typical speed-time working condition construction method is simple, and can be used as a standard driving working condition for urban rail transit train energy consumption simulation / testing to compare and analyze energy consumption of the train under different influence factors.
Description
technical field [0001] The invention belongs to the technical field of simplification of working conditions of rail transit lines, and in particular relates to a method for constructing typical speed-time running working conditions of rail vehicles in an area. Background technique [0002] The factors that affect the energy consumption of trains in urban rail transit are mainly the operating conditions of the trains. The speed curve and weight of the train between stations determine the traction force of the train between stations, which in turn determines the energy consumption of urban rail trains between stations. However, at present, there are many constructions and researches on the driving conditions of automobiles in my country, but there are few achievements in the construction of working conditions suitable for energy consumption analysis of rail vehicles. Therefore, it is urgent to carry out the analysis of the driving data of urban rail lines, and construct the t...
