75m~(3) mining electric loader according to the braking torque and the former structural space.

In this paper,the principle and application method that in relation to a kind of dynamic torque remote sensing testing system are described,the calibration principle of the system is presented,and the detail calibration method is introduced.

Using wireless short range remote control test and power supply technology,the paper develops dynamic torque test apparatus.

Verifying the effect of the friction between teeth on the output torque fluctuation of a spur gearing through the use of experimental method;

A-operator method(AOM) is used to study the influence of the torque fluctuation and time-varying meshing stiffness on rattling threshold speed of the gear system.

It was used to investigate the response to time-varying mesh stiffness, torque fluctuation and errors of gear pair.

Application of AutoLisp on calculation of the drive torque of valve

Injection pressures, drive torque for EUP and low pressure of fuel were collected and filtered, and the peak injection pressure, injection timing, peak torque value and their differences among 6 cylinders were calculated and achieved for the analysis of an EUP assembly.

This paper conducted a study on motion specifitity of outer geneva mechanism,and gave out a non-dimension calculating method of driving torque about this mechanism by introducing non-dimension method.

Based on the analysis of air gap magnetic field,a method is put forward for calculating the driving torque in a permanent magnet coupling and applied to the calculation and research of the practical coaxial permanent magnet coupling.
