Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 The working conditions (i.e., gas content, working pressure, and working temperature) of oil in the actual hydraulic system are always in a dynamic process, which will cause the basic properties of oil (i.e., density, absolute viscosity, and effective bulk modulus) to change and further generate changes of the flow characteristics in the straight ...

The Computational Fundamentals of Spatial Cycloidal Gearing [PDF]
, 2009 The tooth flanks of bevel gears with involute teeth are still cut using approximations such as Tredgold’s and octoid curves, while the geometry of the exact spherical involute is well known. The modeling of the tooth flanks of gears with skew axes, however, still represents a challenge to geometers.

Research on adaptive cruise control algorithm considering road conditions
IET Intelligent Transport Systems, Volume 15, Issue 12, Page 1478-1493, December 2021., 2021 Abstract As one of the most important ADAS systems, traditional adaptive cruise control is only suitable for relatively simple working conditions such as expressways, and it is difficult to deal with complex traffic environment and road working conditions.
