In order to meet the special needs of helicopters with sufficient operating time for landing safely under loss-of-lubrication conditions, it is necessary to avoid the scuffing failure and predict the operating time. A spur gear is taken as the research object. Considering the change of moving source of heat on the gear, simplified models are adopted. Both the spatial distribution and the time history...
The aim of this study is to establish a single track shoe with grouser driving model to optimize the track structural parameters and improve the tractive performance of the tracked mining vehicle on soft sediments. The calculation formula of each component force and total driving force about grouser height was obtained through theoretical analysis. The basic parameters and the relationship of mechanical...
