Therefore, Shi [26] designed a correction model based on unknown nodes in which the unknown nodes use their own correction coefficients, and a dynamic weighted DV_Distance localization algorithm is proposed using the ratio of actual Euclidean distance to accumulated hop distance between anchor nodes....
The instantaneous opening speed of the relief valve spool reaches 15.7 m/s, and the hinge point between the top beam and the column is most sensitive to the hysteresis effect (impact coefficient increases by 0.63). Keywords: hydraulic support; rotary impact; dynamic response; mechanical-hydraulic...
Electrical characteristic experiments show that the discharge duration, the evolution of the gliding arc and the fracture frequency are affected by the pressure difference between the inlet and outlet of the igniter (∆p). With the increase in ∆p, the frequency of the trapezoidal envelope in ...
