A New Method for the Kinematic Analysis of Compound Planetary Spur-Gear Train 一种复合轮系运动分析的新方法
At last, we design a compound gear train using some methods presented in the paper. 最后,将其中几种方法用于设计了一个复合齿轮链。
The latest advance and modification mechanism of PET were introduced from the aspects such as blending modification, chemistry modification, nanometer inorganic compound modification. The development direction and the research train of thought of modified PET were pointed out. 主要从共混改性、化学改性、纳米无机物复合改性等几个方面介绍了PET改性的机理和最新进展,并指出了改性PET今后的发展方向和研究思路。
The Application of Compound Planetary Gear Train in the Compass Cart 复式行星轮系在指南机构中的应用
The key of this method is to judge whether there is happened slide or slip by a compound mode of axle speed sensor and radar speed device, in addition adjust the speed and ranging of train according to the speeding values. 该方案中的关键点就是要通过轮轴速度传感器和雷达测速仪相组合的方法来判断列车行驶过程中空转和滑行的发生,同时根据两者的测速值校正列车的行驶速度和走行距离。
Through the optimization of control strategies and using fuzzy predictive-PID compound control, the controller has more merit included predictive control and fuzzy control and makes the control of high-speed train braking process at optimal status throughout, which has no blind side of control. 通过对控制策略的优化,采用模糊预测-PID复合控制,使控制器结合了模糊预测控制以及模糊PID控制的优点,使列车制动过程的控制没有死角,始终处于最优状况。
