To obtain multi-source information generated during the friction process,environment-based design methodology was used to analyze the current situation and demand of tribological test research.A recursive object model of the multi-source information acquisition system was constructed,and by identifying key conflicts and seeking solutions,the scheme design of the system was realized.Through the deployment of multiple sensors and the development of LabVIEW software,a multi-source tribological information acquisition system was developed on a general tribometer,which realized the real-time acquisition,storage and display of multi-source information such as vibration,sound,and sound pressure during the friction process.The system was further integrated into a digital twin virtual entity of the tribometer based on Unity 3D.Meanwhile,in order to facilitate the subsequent utilization of multi-source information,a corresponding signal preprocessing method was proposed.The test verifies that the system meets the requirements of multi-source information acquisition during friction tests,and can provide a data basis for subsequent multi-source information fusion and multi-disciplinary information association mapping,as well as the realization of tribological state monitoring based on derived state information.
