The artillery firing process will instantly produce high-temperature and high-pressure gunpowder gas, this process will produce shock waves. The gunpowder gas has a limited effect on the projectile during the firing and ballistic after-effects period, ho
- The K factor is the ratio between the distance from the neutral bending line to the innerpress brakebending radius and the material thickness. The calculation formula of K factor is: K factor = δ/T The Y factor is determined by the K factor. - The Y factor is the ratio of the ne...
the output of horsepower torque is getting larger and larger. According to the calculation formula of friction force, we know that in addition to the friction coefficient of the clutch piece, the ability to transmit power of the clutch piece is increased (in fact, the clutch slip is reduced)...
The above research shows that the researchers use the method of experiment combined with computer numerical analysis, based on the working environment of the rail vehicle and the principle of braking, analyze the wear factors of the brake disc, optimize the wear calculation formula, and provide tec...
