Confusion caused by the ramp

 

§01 slope Road production and replacement

   Yesterday God ,  In the official account, some students shared their own ramps ,  Simple 、 cheap 、 practical .  It embodies a strong practical ability .  Compared the ramp they had bought before .  This ramp is accurate ,  Or in the degree of firmness .

  

   Because of the epidemic , Most of this year's sub divisions 、  The provincial competition area adopts the online competition mode .  In order to adapt to the actual conditions of most students preparing for the competition ,  The design size of the online race track is small , Distribution in 5×5 Within the area of .  This makes the ramp on the track can only be deployed in the three fork road building .

  

   According to the competition task , For multi vehicle groups , Due to the need to complete the convergence and separation of the middle vehicle models at the three fork road ,  So at two fork roads   You can't deploy the ramp .

  

   So , Some students put forward A problem ：  How to quickly remove the ramp from the track .

  

   For this question , The real difficulty is .  Paved on the ramp PVC Track surface and electromagnetic guide wire .  After evacuation of ramp ,  The length of the track surface will exceed the length of the ramp itself .  Although the ramp is not very high and steep ,  However, the slope will be deformed after evacuation .

  

   about PVC Material , It is easy to solve ,  Just put the extra   The material can be cut off .   For the electromagnetic lines on the track surface ,  If cutting , Welding is also required , More trouble ,  So how to deal with the extra length .
  

   The way to deal with it is also relatively simple ,  As long as the excess electromagnetic conductivity   Just overlap the leads .  Because the current size and frequency in the electromagnetic wire are very small ,  The external space magnetic field formed is the linear superposition of each section of current .  Linear stacking is important ,  This makes the sum of the external magnetic field of the wire and the sum of the passing current related .  therefore , The guiding magnetic field generated by the superimposed electromagnetic guide wire is the same as that of a single strand .

   Ben This paper gives the results of the ramp evacuation from the track , How to deal with the racetrack and electromagnetic guide wire . As mentioned above , It is necessary to arrange the multi vehicle formation for the final competition , In this way, the track will not affect other groups after correction .
