【摘要】：衬垫的粘接工艺是保证自润滑关节轴承的服役性能和寿命的关键因素。当前对粘接工艺参数的研究不够深入,尚未形成完善的衬垫粘接工艺规范体系,因此,研究自润滑关节轴承的衬垫粘接技术,优化工艺参数,具有重要的理论价值和实际意义。本文主要的研究工作如下:(1)根据自润滑衬垫粘接的要求,设计固化夹具。根据美军标AS81819的要求,为了有效地评价衬垫的粘接强度,设计剥离强度测量仪。(2)应用ANSYS仿真技术平台对衬垫粘接过程进行数值模拟,建立热-结构耦合模型,得到粘接过程中衬垫的温度和应力分布,为衬垫粘接试验中固化参数的设定奠定了基础。(3)设计衬垫粘接试验方案,详细地研究了试件和胶粘剂的选择、加载方案的确立、粘接试验的步骤等内容,同时给出剥离试验的数据处理方法,以及有效剥离强度和偏离系数的计算公式。(4)利用正交试验方法分别按照固化工艺参数、表面粗糙度、涂胶量三个粘接工艺参数进行衬垫粘接试验;以衬垫的剥离强度作为粘接效果的评价标准,对衬垫进行剥离试验,得到各个试件的剥离曲线;对试验结果进行总结和分析,比较各个参数对衬垫粘接效果的影响程度,进而得到粘接过程中各个工艺参数的最优值。
[Abstract]:The bonding process of liner is a key factor to ensure the service performance and life of self-lubricating joint bearing. At present, the research on the bonding process parameters is not deep enough, and a perfect system of liner bonding technology has not been formed. Therefore, it is of great theoretical value and practical significance to study the pad bonding technology of self-lubricating joint bearings and to optimize the technological parameters. The main research work of this paper is as follows: (1) according to the requirement of self-lubricating liner bonding, the curing fixture is designed. According to the requirements of the US military standard AS81819, in order to evaluate the adhesive strength of the gasket effectively, a peeling strength measuring instrument is designed. The ANSYS simulation technology platform is used to simulate the bonding process of the liner, and the thermal-structural coupling model is established. The temperature and stress distribution of the gasket during the bonding process were obtained, which laid a foundation for setting the curing parameters in the bonding test of the gasket. The design of the pad adhesion test scheme was carried out. The selection of the test piece and the adhesive and the establishment of the loading scheme were studied in detail. At the same time, the data processing method of the peeling test and the calculation formula of effective peeling strength and deviation coefficient are given. The orthogonal test method is used according to the curing process parameters and the surface roughness, respectively. Using the peeling strength of the liner as the evaluation standard of the adhesive effect, the peeling curve of each specimen is obtained by the peeling test, and the test results are summarized and analyzed. By comparing the influence of each parameter on the bonding effect of the gasket, the optimum value of each technological parameter in the bonding process is obtained.
