Clutch torque dynamic self-calibration platform and method

Abstract

The invention provides a clutch torque dynamic self-calibration platform. The clutch torque dynamic self-calibration platform comprises a power module, a clutch module, a torque detector and a load module which are connected in sequence, as well as an upper computer industrial control system which is connected with the power module, the clutch module, the torque detector and the load module, wherein the upper computer industrial control system comprises a data calibration and analysis module and a logical control module which are connected with each other; the data calibration and analysis module is connected with the power module, the torque sensor and the torque detector respectively; and the logical control module is connected with the power module and the load module respectively. According to the clutch torque dynamic self-calibration platform, the output power of the power module is adjusted according to a control strategy which is made in advance on the basis of the inherent torque disengagement characteristic of a clutch, and a strain signal is acquired, transmitted and calibrated automatically, so that measuring range check and extreme torque calibration are realized through characteristic matching of the acquired signal. Correspondingly, the invention also provides a clutch torque dynamic self-calibration method.

Description

technical field [0001] The invention relates to the field of torque monitoring, in particular to a clutch torque dynamic self-calibration platform and method. Background technique [0002] The clutch is a power transmission device, which is mainly installed between the power device and the actuator to combine or disconnect the power transmission. According to different control methods, the clutch has mechanical control, hydraulic control, air control, vacuum source control, electromagnetic and other manipulation methods. According to the different friction modes, the clutches are divided into jaw type, single friction plate and multi-plate friction plate. [0003] Clutches have been widely used in industries, automobiles and other fields as well as construction machinery. For example, the domestic method to protect key equipment from overload damage is to set the motor current protection and use the mechanical overload clutch (also known as clutch torque limiter). However...
