With the windage size under speed class and under different natural winds, it is stored with different wind-force, speed class in memory
When the first power influence coefficient.
Road moisture to rail vehicle run influence mainly on the rail of different dry and wet situations, rail vehicle with
Glutinous sliding coefficient between rail is different, causes the acceleration time of rail vehicle different, it is wet to be stored with different roads in memory
The second power when spending influences coefficient.
Road grade is mainly gravity direction and rail vehicle when in different gradient to the influence that rail vehicle is run
Traffic direction out of plumb, the gravity of rail vehicle can be decomposed into a component on its traffic direction and vertically and railcar
Another component on direction, the two component can all have an impact the adhesion of rail rail vehicle, in memory
Third power when being stored with different road grades influences coefficient.
Power needed under the operating status of rail vehicle is also different, and the operating status of rail vehicle includes accelerating to start
Stage, constant rate period, unpowered coasting stage, electric braking or mechanical braking stage, it is stored with different operation shapes in memory
The 4th power when state influences coefficient.
Specifically, processor is influencing the specific of coefficient acquisition analog DC according to the power stored in memory
Process is：
Since dcdc converter is connect with simulating contact net, dcdc converter is used to obtain the net pressure of simulating contact net, and
Via controller is sent to processor, the operating parameter that processor is engraved according to actual track vehicle input by user when each, for
Each operating parameter, obtaining its corresponding power influences coefficient, influences system according to the actual value size of each operating parameter and power
Number, acquisition actual track vehicle engrave corresponding power when each, further according to the net pressure for the simulating contact net that controller is sent, obtain
Corresponding actual DC electric current is engraved when taking actual track vehicle each, since actual DC current value is excessive, laboratory condition
Do not support, therefore it is straight by actual DC electric current progress equal proportion to convert to obtain the corresponding simulation of analog orbit vehicle each moment
Galvanic electricity stream.
Optionally, with the operating parameter at a certain moment input by user be respectively wind-force be 2, road moisture 2, road
The gradient is 2, the operating status of actual track vehicle is constant rate period, the corresponding work(of above-mentioned operating parameter stored in memory
It is respectively to illustrate for 3,4,5,6 that rate, which influences coefficient,；The corresponding power of actual track vehicle is 2*3+2*4+2*5+2*6
=36；The net pressure for the simulating contact net that controller is sent is 2, since net pressure is the contact net net pressure in simulator,
It is 20 that the contact net net pressure that equal proportion conversion is actual track vehicle, which need to be passed through, therefore actual DC electric current is 36/20=
1.8, analog DC is 0.18 after equal proportion is converted, and the voltage that is wherein used in the present embodiment, electric current conversion are than can be with
Conversion in above-described embodiment is than identical.What those skilled in the art can mutually arrive is according to the operating parameter, operating parameter
Corresponding power influences the net pressure of coefficient and simulating contact net, otherwise obtains each moment correspondence of analog orbit vehicle
Analog DC.
