A method for real-time monitoring of dual sheet deformation by sensor

Abstract

The invention provides a real-time dual disc deformation monitoring method through sensors. N holes are made on m diameters of radial equal center angles of a friction plate, each hole is fixedly equipped with one sensor, and the sensor is used for measuring a distance between the friction plate and a dual disc and transmitting the distance to a computer; the dual disc is guaranteed to be in a static state when a liquid viscosity speed control clutch starts; before the liquid viscosity speed control clutch starts, the distance between the friction plate and the dual disc is measured as a reference distance; after the liquid viscosity speed control clutch starts for a while, data measured by the sensors is recorded; the recorded data matrix is analyzed, and deformation conditions of the dual disc are determined. The method is advantaged in that through continuously detecting change of the distances between the active and passive friction plates, radial and circumferential deformation conditions of the dual disc are determined, summation of deformation rules of the dual disc is facilitated, measurement precision is high, the small deformation scope of the dual disc can be monitored,work efficiency is high, deformation of the dual disc can be monitored in real time, and problems are timey discovered to avoid generation of faults.

Problems solved by technology

[0003] Due to the fact that the dual plate is often under severe working conditions such as high temperature, high pressure, and alternating load, the dual plate will have deformation, cracking, fatigue cracks, wear and other undesirable phenomena due to temperature rise during the working process, among which thermal deformation is the main failure form. , the deformation of the dual plate seriously affects the transmission performance and service life of the fluid-viscous transmission clutch, and may even cause major safety accidents, so the detection of the deformation of the dual plate is particularly important

[0004] The current method of detecting the deformation of the dual plate is to take out the dual plate that has been working for a certain period of time, and then measure the disc shape, warpage or other deformation of the dual plate. This method is inefficient and cannot detect the deformation of the dual plate in time, which will lead to Damage to production equipment, waste of energy
