基于射线技术的内燃机缸套油膜厚度可监测性
|
摘要
研究基于射线透射技术的内燃机缸套油膜厚度的可监测性,用一套自制的标准厚度润滑油膜容器在X射线透射测厚仪上进行油膜测厚标定试验,得到了线性良好的标定曲线。将标定数据输入到同一台测厚仪上,检测到了金属薄板表面0.011~0.984 mm的润滑油膜厚度。分析了适用于缸套油膜厚度的射线透射测厚系统参数的设置,并提出射线测厚装置在实际内燃机上的布置方式和布置要素,由此得出结论:射线透射技术监测大型低速内燃机缸套油膜厚度是可行的。另外,射线测厚系统过大的油膜厚度信号可作为摩擦副异常磨损的一种诊断信号。
To study the detectability of the OFT in IC engine based on ray transmission technique,a set of homemade standard container was used to calibrate the OFT using the X-ray transmission thickness tester,the calibration curve with reliable linearity was obtained.The calibration parameters were then programmed into the thickness tester for OFT detection. The lubricating film thickness of 0.011 to 0.984 mm on the surface of a metal sheet was detected.The setting of the parameters of the thickness of the cylinder liner was analyzed,The layout and layout elements of the X-ray thickness device in the actual internal combustion engine were presented.In conclusion,the detection of the OFT of cylinder liner in large-scale low-speed IC engine based on ray transmission technique is feasible.In addition,the large oil film thickness signal can be used as a diagnostic signal for abnormal wear.
