Question

What is meant by damping torque?

Answer 1

In order to answer this question, we will go through the whole concept or the process of damping torque, and we will discuss the mechanism also. We will also discuss the utilisation of damping torque.

Complete answer:
Damping torque is a physical mechanism for managing the movement of a system by providing motion that opposes the system's natural oscillation. It acts only while a system is in motion, similar to friction, and is absent when the system is at rest. Its main function is to provide quick and precise measurements for oscillating systems.
The indicating instrument provides damping torque. Any mechanism utilised for vibration energy absorption, shaft vibration suppression, soft start, and overload protection is referred to as a damper. It is critical to first calculate the damping torque in order to design an efficient damper. The speed deviation of an electromechanical torque deviation of a machine is known as damping torque, while the angle deviation is known as synchronising torque. The damping torque is required in a measuring instrument to bring the moving system to a stop and exhibit stable reflection in an acceptable amount of time. It only exists as long as the pointer is moving. The pointer oscillates for a short time in the absence of damping torque before returning to a steady position, which is referred to as under damping. Over damping occurs when the damping force is too great, causing the pointer to slowly come to a stop.
Uses of Damping Torque: Damping torque is utilised to allow for quick and precise reading of an oscillating object. An item in motion tends to continue in motion due to inertia, necessitating the application of a counteracting force to bring it to its final rate of oscillation in a short amount of time. Damping torque does this by resisting natural oscillation, allowing the user to obtain a precise measurement.

Note: A damping torque is created by a halting or damping force that occurs only when the moving system is moving and always opposes its motion. To quickly bring the pointer to a stop, such a torque is required.
