Compressed supporting roller temperature analysis method based on mechanics and thermodynamics

Abstract

The invention discloses a compressed supporting roller temperature analysis method based on mechanics and thermodynamics. The method comprises the following steps of S2, equidistantly arranging several groups of thermodetectors around a supporting roller, and using a laser range finder to measure distance data H between photosensitive components of the thermodetectors and the supporting roller; S3, using a data acquisition module to receive the distance data H and temperature data detected by the thermodetectors, and then calculating an actual temperature T of a surface of the supporting roller B via a temperature loss calculation module according to the distance data H and the temperature data T1; and S4, at the same time, using a hydraulic cylinder to press the supporting roller B, recording a corresponding pressure F value by a control computer of the hydraulic cylinder, and ensuring that the pressure of the supporting roller B is within a maximum displacement deformation amount and a plastic deformation energy value; In the invention, an electrical signal can be smoothly input, a common-mode noise can be eliminated, an emission signal is amplified and data transmission precision is increased. The temperature loss calculation module calculates the actual temperature T of the surface of the supporting roller B, which is beneficial to improving accuracy of an analysis result.

Description

technical field [0001] The invention belongs to the technical field of temperature analysis of a pressure supporting wheel, and more specifically relates to a temperature analysis method of a pressure supporting wheel based on mechanics and thermodynamics. Background technique [0002] At present, it is impossible to predict the thermodynamic state that may appear in the actual working process of the supporting wheel. If the material and speed are selected based on the mechanical properties of the material and experience, it will definitely affect the service life of the supporting wheel. During the simulation analysis of the thermodynamic state of the supporting wheel, the receiving and processing of the signal is not accurate, which is not conducive to the accurate analysis. Therefore, we propose a temperature analysis method based on mechanics and thermodynamics for the supporting wheel under pressure.
