Abstract

Purpose

The purposes of this paper are optimization of high speed reducer in electric vehicles based on the analysis of lubrication and verification of simulation accuracy and optimization results.

Design/methodology/approach

The traditional CFD method presents poor applicability to complex geometric problems due to grid deformity. Therefore, moving particle semi-implicit (MPS) method is applied in this study to simulate lubrication of the reducer and analyze the influence of input speed and lubrication system design on the distribution. According to the results, the reducer is optimized. Meanwhile, the experiments for lubrication and churning power loss is carried out to verify the accuracy of simulation and optimization effects.

Findings

The flow field of lubricant inside the reducer is obtained. The lubrication system of reducer needs to be improved. Simulation and experiment show that the optimization is sufficient and efficient.

Originality/value

According to the simulation of lubrication, the reducer is optimized. The lubrication experimental setup is established. The conclusion of paper can provide the method and tool for reducer in electric vehicle.

基于润滑分析的电动汽车高速减速器优化方案

本文的目的是基于润滑分析对电动汽车中的高速减速器进行优化，并验证仿真精度和优化结果。设计/方法/途径传统的 CFD 方法由于网格变形，对复杂几何问题的适用性较差。因此，本研究采用移动粒子半隐式（MPS）方法模拟减速器的润滑情况，并分析输入速度和润滑系统设计对润滑分布的影响。根据结果，对减速机进行了优化。研究结果得到了减速机内部润滑油的流场。结果得到了减速器内润滑油的流场，减速器的润滑系统有待改进。原创性/价值根据润滑模拟，对减速器进行了优化。建立了润滑实验装置。本文的结论可为电动汽车中的减速器提供方法和工具。同行评议本文的同行评议记录可在以下网址查阅：https://publons.com/publon/10.1108/ILT-04-2024-0123/。
