| Most of the energy consumed by friction would be converted into heat, then made up one3D(three-dimensional) transient temperature field while transferring in frictionalcomponents. The high temperature caused by heat would have influence on mechanicalproperties of materials and lead to degradation in performance of lubricant. Therefore,study on temperature field of friction can provide important reference for study frictionmechanism and related mechanical design.This thesis focused on the sliding friction pair of end-surface, used different materialsand in the condition of multi-work situations. The study took advantage of multifunctionalcontrollable environment tribometer and a self-made test device to collect real-time frictioncoefficient, in addition, got the approximate temperature of friction contact surface withhigh-precision infrared probe, and gathered non-contact surface temperature of the upperand lower sample with infrared camera during the process of friction. This study made thesecondary development of ANSYS combined C++and APDL (Ansys Parameter DesignLanguage), took the heat flux as boundary condition and considered the problem of thermalcontact, developed one human-computer interaction system to calculate the temperaturefield with APDL packaged by C++, which realized parametric analysis of temperature fieldin ANSYS, and then implemented optimal calculation of temperature field withoptimization algorithm compiled with C++and real-time temperature of specimen surface.The thesis elaborated all details of the research mentioned above. This study simulatedthe transient3D temperature field using measured data as boundary condition, and utilizedC++and APDL for optimal calculation of the temperature field with2D(two-dimensional)temperature data to obtain one more accurate3D frictional temperature field. |
