Numerical analysis model for the instantaneous grinding temperature of face gears with a worm grinding wheel by WANG Chao, GUO Hui, RUAN Yuhang, RAN Xiaoping, ZHAO Ning

“…Finally, the proposed model’s computational accuracy was validated through the test of the grinding temperature.ResultsThe analysis results demonstrate that the instantaneous grinding temperature significantly increases from the inner diameter to the outer diameter at a fixed tooth height position. Moreover, at a constant tooth width position, the temperature gradually rises from the tooth tip to the tooth root, albeit with a small magnitude of variation. …”

Investigation about crack propagation paths in thin rim gears by F. Curà, A. Mura, C. Rosso

“…Considering thin rim gears, when a crack is nucleated near the tooth root, it may propagate through the tooth (causing the loss of the entire tooth or a portion of it) or the propagation may follow a path across the wheel diameter (causing the projection of big parts of the gear that may break the gearbox and may cause serious damage to the aircraft). …”

SIMULATION OF URBAN RAIL VEHICLE CRASH AND FACTORS INFLUNCING ANTI-CLIMBING ABILITY OF ITS ANTI-CLIMBER by CHEN ShuQin, NIU WeiZhong, WEN Tao

“…By use of the finite element software Hypermesh and LS-DYNA,the processes were respectively simulated of urban rail vehicle head car,with and without anti-climbing energy absorption device,impacting the fixed rigid wall face to face at the speed of 12.25 km / h and 18 km / h.Based on the obtained data,the crashworthiness of urban rail vehicle head-car body and performance of its energy absorption device were evaluated.Using the response surface methodology,the factors influencing anticlimbing ability of anti-climber were also studied.The results show that,when the crash speed is respectively at 12.25 km / h and18 km / h,the energy absorption device would absorb impact energy before car body structure by plastic deformation,protecting the car body without and with only a little plastic deformation.In addition,when the total height and tooth thickness of anti-climber are fixed,its anti-climbing ability would decrease as the tooth height and angle increases,and the tooth height has more influence than the angle.…”
