摘要

目的

针对影响齿轮齿条爬升式升船机船厢驱动机构载荷变化的关键因素不明晰的问题，基于采集的船厢运行频次、厢内水深、驱动机构、同步轴系统等运行历史数据，研究了升船机不同运行工况下的齿轮齿条载荷变化规律。

方法

通过数据拟合结果构建了船厢驱动系统力学分析与数值计算模型，通过统计分析系统揭示了船厢不同水深条件、运行工况和各驱动单元载荷不均对齿轮运行载荷的影响机制，并制定针对性的应对策略。

结果

结果显示，船厢匀速升降阶段，齿轮载荷主要由误载水深和系统摩擦阻力构成；加减速阶段受船厢自重及传动系统旋转构件惯性效应影响，载荷出现显著峰值；各驱动单元间载荷离散度较大，且载荷偏差基本不受运行过程、工况条件和整体载荷水平的干扰，表现为随机分布特性。精细化调控船厢水深可实现齿轮载荷优化控制。

Abstract

Objective

To address the unclear key factors affecting loads of the rack‑and‑pinion climbing‑type ship‑lift chamber driving mechanism

based on the collected historical operational data including ship‑chamber operation frequency

water depth inside the chamber

driving mechanisms and synchronizing shaft systems

variation rules of rack‑and‑pinion loads under different operating conditions of the ship‑lift were investigated.

Methods

A mechanical analysis and numerical calculation model for the ship‑chamber driving system was established based on data‑fitting results. Through statistical analysis

the influencing mechanisms of varying water‑depth conditions

operating modes and unbalanced loads among driving units on pinion loads were systematically revealed

and targeted countermeasures were formulated.

Results

The results show that the rack-and-pinion load during the uniform upward and downward movement of the ship chamber is mainly affected by the misladen water depth and the system frictional resistance. During the acceleration and deceleration stages

the inertial loads induced by the self-weight of the ship chamber and the rotating components in the system produce prominent peak values of the rack-and-pinion loads. There are significant deviations in the rack-and-pinion loads among drive units

which are basically unaffected by the operation process

operating conditions and overall load conditions of the ship lift

presenting a random distribution characteristic. Optimized control over pinion loads can be achieved through precise regulation of chamber water depth.
