北京BJ3364矿用汽车液压转向机的改进

液压转向机是重型汽车的重要部件之一，对汽车安全行驶，维修费用有重要的影响，根据较长期的生产实践，验证了油泵最高限定油压，供油量，滑阀顶开缝隙，最大密封重合度等参数调整改进的必要性及改进后的效果。     

S^2 BHCA Multiple AUVs cooperation oriented control architecture

Oceanographic survey, or other similar applications should be the applications of multiple AUVs. In this paper, the skill ＆ simulation based hybrid control architecture （S^2BHCA） as the controller＇s design reference was proposed. It is a multi-robot cooperation oriented intelligent control architecture based on hybrid ideas. The S^2BHCA attempts to incorporate the virtues of the reactive controller and of the deliberative controller by introducing the concept of the ＂skill＂. The additional online task simulation ability for cooperation is supported, too. As an application, a multiple AUV control system was developed with three ＂skills＂ for the MCM mission including two different cooperative tasks. The simulation and the sea trials show that simple task expression, fast reaction and better cooperation support can be achieved by realizing the AUV controller based on the S^2BHCA.

根据油质分析自动变速器故障

自动变速器零部件的损坏形式主要有两种，一种是自然磨损，另一种是突然损坏。这两种形式的损坏（特别是自然磨损）都伴有杂质产生，部件在磨损中产生的杂质大部分会沉积在油底壳中。这些杂质的成分非常复杂，橡胶件、尼龙件碎块和离合器、制动器等材料比较容易辨认，而一些金属磨粒，特别是一些细小的磨粒就比较难以辨认了。这就要求维修人员熟悉自动变速器各部件的材质，如变速器壳体由铝合金制成；摩擦片的两面均为摩擦系数较大的铜基粉末冶金层或合成纤维层；离合器、制动带的活塞密封圈是橡胶件；齿轮、轴承、轴、油泵齿轮等为钢结构件。
