Virtual Torque and Rotational Speed Measuring Device

The measurement principles of torque and rotational speed were analysed.A virtual torque and rotational speed measuring device was presented,which can be used to measure torque and rotational speed conveniently and accurately.The methods of designing virtual torque and rotational speed measuring device were introduced.Electrorheological experiments were carried out using this device.It shows experimentally that virtual torque and rotational speed measuring device has high accuracy and good anti-jamming ability,and the operation is simple.The virtual torque and rotational speed measuring device can be put into practical applications.
