摘要：磨损是目前人字闸门底枢摩擦副失效的重要形式，本文从工程实际和等效模拟磨损试验出发，基于摩擦学基础理论的研究成果，结合常见人字闸门底枢摩擦副的工作原理、结构特点、接触模型和磨损失效问题，利用接触疲劳、弹流润滑、磨损预测与演化规律等摩擦学的基本理论和方法，选用国内人字闸门运行参数和相同工况条件下的底枢摩擦副模拟磨损试验数据对底枢摩擦学设计和分析方法进行深入探讨。采用C#编程语言和MATLAB程序语言，开发了基于磨损失效评估的人字闸门底枢摩擦副设计系统计算软件。该系统软件具有良好的人机交互功能，通过简单的数据输入获得底枢接触应力大小以及预估使用寿命，为我国同类底枢的设计与维修更换提供精准快捷方法，节省了重新计算与设计的时间。

Abstract：Wear is a significant cause of the failure of the bottom hinge friction pairs of minter gate. This article studies the gate bottom hinge tribology design and analysis methods based on the operating parameters of bottom hinge friction pairs of minter gate made in China and the data of the simulated wear test data under the same working conditions by adopting the basic theories and methods of tribology such as contact fatigue, elastohydrodynamic lubrication, wear prediction and evolution law while takes account of the actual situation of the project, the result of equivalent simulated wear test, and the factors including the working mechanism, structural characteristics, contact model and wear failure problem of common bottom hinge friction pairs of minter gate. And a calculation software for the design system of the gate bottom hinge friction pairs based on the evaluation of wear and failure is developed by using C# and MATLAB programming languages. Since the software has great human-computer interaction function, the contact stress and the estimated service life of the gate bottom hinge can be obtained through simple data input, which provides an accurate and quick methods for design, maintenance and replacement of similar gate bottom hinge friction pairs, thus greatly saves the time of recalculation and re-design.
Key words：miter gate；bottom hinge friction pair；wear failure；user interface；software development
