Afterwards, we propose a new constant coefficients measurement method in dynamic equation of robot manipulators, this measurement method includes three groups of experiments: group one, let each joint of robot manipulator keep static to measure the constant coefficients in gravity term of dynamic equation and Coulomb frictional torque, group two: let only one joint of robot manipulator move at a constant velocity to measure the viscous frictional coefficient and constant coefficients in effective inertia of dynamic equation, group three: let only one joint of robot manipulator move at constant acceleration at a time to measure constant coefficients in Coriolis and centrifugal term and coupling inertia of dynamic equation.

让操作器单个关节恒速运动，在对驱动系统中传动机构，减速装置和电感系数综合考虑的基础上，这组实验对粘滞摩擦系数及有效惯量中常数系数进行测量。这种测量方法只要求旋转关节的驱动电机施加恒定电压，回转关节驱动电机施加正弦波电压。3。让操作器单个关节恒加速运动，这组实验测量动力学方程中哥氏力、离心力项和耦合惯量项中的常数系数，这种测量方法只要求单个关节匀加速运动，而其它各关节保持静止，这种测量方法虽然要求关节匀加速运动，但不必进行关节角加速度检测，而只需进行关节角位移和角速度检测即可，输入量直接给定为输入电压。

The key to this yield criterion is that the concept of internal friction angle which used in soil mechanics has been introduced to infer the relationships among poisson ratio, internal friction angle and relative density.

并且在Miss屈服准则的基础上论证了粉末体屈服准则在主应力空间，为一个回转椭球体。

A brand new open-center pneumatic cylinder was developed by JATO Precision for the high speed and high accuracy CNC lathes which use spring collets to clamp work-parts.

JATO Precision针对高转速，高精度，使用弹性筒夹夹持工作物的小型数控车床，开发了一款全新的高速中空气压回转缸JAL636-PL。

JATO JAL636-PL pneumatic cylinder has extremely low temperature rising to avoid thermal error of spindle system of CNC lathes, and it also largely decreases building cost of the machine since no hydraulic pump, tank and cooler is needed.

应用JAL636-PL气压回转缸，数控机床能有效的降低主轴热温升造成的精度误差，并且大幅降低机床本身的建造成本。
