利用伺服电机的可控性实现对冲压滑块下死点位置、速度的控制，进而提高精压机的通用性。

Lower dead position of ram and speed control have been realized by controllable servo motor , hence improved adaptability .

使用这个方法，单元会漫步于死点位置，重复做相同的错误选择，直到他们发现周围的路。

Using this approach , units will wander down dead ends and make similar wrong choices until they have learned their way around .

文中讨论了曲柄滑块机构中滑块质量、滑块速度、温度和运动副间隙对滑块死点位置的影响。

This paper discusses the effects of the slider 's weight and speed , temperature and joints clearance on dead-point precision of slide-block in crank-slider mechanism .

在曲柄摇杆机构中，当以摇杆为原动件时，工作一个循环以后，直观看出有两次死点位置出现。

In the crank and rocker mechanism , when the rocker acts as the driving link , there will be two dead points in one working cycle .

从机构学角度分析了操作臂运动特性，给出了操作臂作业的几个特殊位置，分析了操作臂死点位置，提出避免死点的方法。

Kinematics characteristic and several especial locations for operating arm are analyzed , as well as dead point of the mechanism and means how to keep away from it is given .

结果表明，单个杆件尺寸误差与滑块下死点的位置误差成线性关系，其中曲柄长度影响最大，影响系数为0.021，滑块下死点的位置误差随运动副间隙的增大而增大。

Simulation results show that relationship between single rod size error and the dead point position error of the slider is linear , of which the greatest impact is crank length , impact factor is 0.021 .

实例计算结果表明，当钻井泵活塞处于两死点邻近位置时，活塞杆和连杆的受力均值和方差急剧波动，工作可靠性严重下降。

Example calculation shows there are abrupt fluctuations of the mean value and variance of forces on both the piston rod and connecting rod when the piston is near the two dead points , and this will exert a serious influence on service reliability .
