Because the inner space of a hollow track is small, a driving wheel is arranged outside the hollow track in the prior art, and a dolly is driven to move by friction force generated by spring force. 由于空腹轨道内空间小,驱动轮安装在空腹轨道外部,靠弹簧力产生的摩擦力带动小车运行。
In each stage, the vertical and horizontal forces of inner and outer rails, the coefficient of derailment and the rate of wheel load reduction, and the displacement of the railhead should be tested, and the elasticity crowding amount of the track distance calculated. 然后计算出脱轨系数和轮重减载率,测试轨头位移,计算出轨距弹性挤开量。
Among the foreign players, the Korean usually take the action of the inner track exceeding technique at curie in order to exceed the others. 国外韩国运动员多在出弯道处做内道超越技术动作实现超越。
In the aspect of eliminated technique, this paper emphases to investigate the series active power filter and shunt series active power filter, dispart the series active power filter control into two-layer structure, the inner layer face the main loop to track the reference current or voltage. 在谐波抑制方面,本文对当前研究的热点&串联和并联有源滤波器进行了理论分析,将电力有源滤波器控制分为两层结构,内层直接面向电力电子主回路,实现指令电流或是电压的跟踪。
In the inner control loop, a carrier-based current controller is used to track the line current command. 在内部控制回路中,用基于载波的电流控制器跟踪线电流信号。
The inner loop controller consists of two SISO pressure controllers designed by nonlinear perturbation observer theory which are used to track desired pressure under system disturbances. 内环级采用两个基于扰动估计观测的单输入单输出液压缸非线性压力控制器,用于在有扰动情况下实现对每个提升缸期望负载压力的精确跟踪控制。
Excessive friction or even squeezing will occur between the rim and the inner side of the track when the space between them is too small. 当这种间隙过小就会引起轮缘与铁轨内侧的严重摩擦甚至挤压,这种现象称之为啃轨。
Decoupled control structure consisting of current feedback and voltage feed-forward is adopted in the inner current control loop which can track the reference current quickly. 内环电流控制器采用电流反馈和电压前馈的解耦控制策略,实现电流的快速跟踪控制;
The outer loop controller is the speed controller, and the inner loop controller is the current controller, both using PI control algorithm to automatically recognize the welding track and to accurately track and control. 外环控制器是速度控制器,内环控制器是电流控制器,控制器采用PI控制算法,实现对焊接路径的自动识别及精确跟踪控制。
In the inner flow field of the turbine, the distributions of temperature, pressure and velocity accord with the principle of gas dynamics. The flow track of the gas in volute is similar to the logarithmic spiral. 蜗壳中流场的温度、压力和流速的分布规律和变化情况满足气体动力学原理,并且蜗壳内气体的流动轨迹近似于对数螺旋线。
The inner current loop proportional controller can speed up the current track and speed, therefore this paper, the proportion of resonance control technology. 而电流内环采用比例控制器又可以加快电流的跟踪速度,故而本文采用电流内环控制电压外环比例谐振控制技术。
This, to a certain extent influence the west Inner Mongolia region in track and field course of development. 4. 这在一定程度上影响了田径课在内蒙古西部地区的开展。
By studying the variety of inner structure of stars, an attitude that different demarcation point of stellar evolutional stages can affects the evolutionary track in the Hertzsprung-Russell diagram is developed, based on mass loss rate is a consecutive piecewise function in the stellar evolution calculations. 通过分析恒星内部结构的变化,基于在演化计算中质量损失率公式应采取连续的分段函数的考虑,提出恒星演化阶段的分界点的不同会影响恒星在赫罗图中演化轨迹的观点。
