Climb rail derailment course in conjunction with wheel 6, it is as follows that its derailing detects specific descriptions:
One, normal condition
As shown in Figure 6, when railway vehicle normally runs in orbit, wheel 6 does small size serpentine locomotion centered by rail 5 line of centers, and wheel 6 wheel rim does not cling on rail 5, and wheel 6 is relative to the Uplifting amount h of rail 5
mbe zero;
Two, wheel rim reclines state
As shown in Figure 7, if under certain specified conditions, wheel 6 gives the transverse force of rail 5 very large, and wheel 6 gives the vertical force of rail 5 very little, so that the contact point that wheel 6 is new in rolling process shifts to wheel rim top gradually, wheel 6 raises gradually, and wheel 6 is relative to the Uplifting amount h of rail 5
mincrease gradually, work as h
mvalue is greater than safety value, this secondary data of processor for recording h
m, be labeled as 1 time;
Three, continue to climb track-like state
As shown in Figure 8, if the position of contact point arrives the flex point on wheel rim arc surface on wheel rim, namely during maximum some in wheel rim root and wheel rim inclination angle, circular sliding slopes place, middle part, climb the transformation point of rail with regard to arrival.If transverse force reduces or vertical force increases before arrival transformation point, then take turns still may slide downward, return to original settling position.After contact point postcritical, if the change of transverse force, vertical force is little, wheel 6 is likely climbed up rail 5 gradually and derails.
In this process, wheel 6 is relative to the Uplifting amount h of rail 5
mvalue continues to increase, h
m+1be greater than h
m, be labeled as 2 times, h
m+2be greater than h
m+1, be labeled as 3 times, then send alerting signal;
Four, derailing state
As shown in Figure 9, if wheel 6 continues to climb rail, rail 5 will be climbed up until wheel rim top reaches rail 5 end face and derails.
