Influence of Polygon Wheel on Dynamic Performance of Meter-gauge Locomotive by Jingtao HU, Jiuhe YANG, Junjun DING, Zhaoxi LI, Fu LI

“…At last, the change trend of wheel-rail vertical forces was studied under the joint action of polygon wheel and track excitation. The results showed that due to the low running speed of the meter-gauge locomotive, the polygon wheel will form low frequency vibration which will increase the vibration response of the car body; the polygon wheel will greatly increase the wheel-rail vertical forces, but it has little effect on the derailment coefficient; the wave depth limit is inversely proportional to the running speed of the locomotive and the harmonic order; the track excitation will not cover the trend caused by polygon wheel, but it will greatly increase the wheel-rail vertical forces. …”

CALCULATION OF LOADS ON THE CONTROLS WITH HELICOPTER MAIN ROTOR OF SINGLE-ROTOR DESIGN by B. L. Artamonov, M. M. Kruchinin

“…On the basis of the hinge moments values data loads on rotorcraft rotating ring, arising at different azimuthal location of the rotating main rotor blades are calculated.The calculations executed on the example of Mi-34 helicopter main rotor have shown that average loads in one revolution in the channel of collective pitch control increase in a control path at flying speed. At the same time loads in the channel of longitudinal control make up to 80 % of loads in the channel of collective pitch control, and in the channel oflateral control - to 40 % that will well be coordinated with the provided data of flight tests.…”
