Q is the vertical force that wheel acts on rail;
Evaluation method: derailment coefficients limit value 0.8 is above applicable to the situation that sweep is greater than 250m, when sweep is less than 250m, derailment coefficients limit value can be loosened to 1.2.
2) wheel shaft transverse force should meet following condition:
ΣY 2m≤10+P 0/3
In formula, ∑ Y 2mit is wheel shaft transverse force;
P oit is dead axle weight.
3) maximum vertical wheel rail force should meet following condition:
Q≤Q lim=Q 0+90
In formula, Q is vertical wheel rail force;
Q 0quiet wheel load, with kN unit representation;
Q limit is the ultimate value representing vertical wheel rail force.
4) rate of wheel load reduction should meet following condition:
d Q Q a ≤ 0.65 (1st limit)
d Q Q a ≤ 0.60 (2nd limit)
Wherein, dQ is wheel unloading amount (kN);
Q afor the average wheel load (kN) of increment of load and off-load side wheel;
1st limit in above formula is the criterion of acceptability of evaluation vehicle operating safety, and 2nd limit is the standard increasing safety allowance.Rate of wheel load reduction be used for whether causing because single wheel off-load is excessive derailing (be generally used for low speed by sharp radius curve, transverse force be zero or close to zero situation).
This kind of method of testing can be tested for various different gauge, different rail truck, can service test device to greatest extent, highly versatile, saves test fund, and can ensure that test result is accurate in theory, to guaranteeing that high-speed railway safe operation etc. is of great significance.
In test, can according to actual conditions by controlling the different line condition of the action simulation of each vertical actuator, at the trial according to circuit superelevation situation, testing table adjustment is become the state needing simulation, then by tested vehicle counterweight, make it reach real circuit ruuning situation, simulate the actual operating state of tested vehicle in real circuit with this, thus measure its vertical vibroshock performance, for train vertical damping study mechanism provides more authentic and valid test figure.
In addition, this test method can carry out repeatedly repetition test, and the time cycle used in process of the test is short, the manpower of needs, and the costs such as material resources are lower, and the efficiency of test is higher, does not affect the normal operation of train at the trial, is convenient to implement.
As mentioned above, plan content given by reference to the accompanying drawings, can derive similar technical scheme.In every case be the content not departing from technical solution of the present invention, any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
