Abstract

The work aims to address the issues of vibration monitoring and mechanical coupling efficiency in the lubricating oil pipeline system for a certain gearbox.A vibration sensor (FVS) withwide frequency band, high flexibility and flexible contact-separation mode was designed based on the principle of friction nano-generator. By introducing PTFE powder with different particle sizes as friction material, the effect of different particle sizes of PTFE powder on the electrical output performance of the sensor was studied, and the optimal particle size was found. Furthermore, the sensitivity, directivity, stability, distance response and vibration response of the sensor were tested. Finally, flexible sensors were respectively arranged at the inlet and outlet of the lubricating oil pipeline of the gearbox pump set and the inlet and outlet of the check valve overflow valve to monitor the pipeline vibration of the gearbox under different working conditions and judge the working conditions of the lubricating oil pump and the lubricating oil pipeline there.When 50 μm and 20μm PTFE powderswere mixed in a ratio of 3:4, the sensor showed the best electrical output performance. Within the test acceleration range, the FVS exhibited a sensitivity of approximately 0.169-0.411 mV/(m/s2), with a maximum initial sensitivity of about 0.411 mV/(m/s2) under low acceleration conditions, and had good frequency response characteristics, directivity, stability and distance response characteristics of 10Hz-20kHz. By arranging flexible sensors at the inlet and outlet of the pump set pipeline and the inlet and outlet of the valve set for monitoring, it was found that the peak value of vibration spectrum and time-frequency diagram could normally reflect the working state of lubricating oil system components when the A-type pump set and the B-type pump set worked simultaneously or independently at different input speeds, which could be effectively applied to pipeline vibration monitoring.The sensor demonstrates a wide frequency response range and high sensitivity, making it particularly valuable for monitoring vibration conditions of gearbox lubricating oil pipelines during subsequent real-ship applications.
