基于大学生方程式大赛KTM690发动机的冷却系统设计

Cooling system design based on the KTM690 engine of the college student formula competition

摘要

中国大学生方程式汽车大赛（FSCC）是由中国汽车工程学会（SAE-China）主办的一项高水平大学生工程赛事，本文针对中国大学生方程式汽车大赛（FSCC）中KTM690单缸发动机在高温、高负荷工况下易出现过热、功率下降及爆震等问题，进行冷却系统的优化设计。通过CFD仿真分析与实物测试相结合的方式，对散热器结构进行系统优化，实现发动机在85-95℃最佳温度区间的稳定运行。研究重点包括轻量化散热器设计、空间布局适配与可靠性验证。该设计为FSCC赛车的冷却系统提供了兼顾轻量化与高效散热实践方案。

Abstract

The Formula Student China (FSCC) is a high-level college student engineering competition sponsored by the Chinese Society of Automotive Engineering (SAE-China). This article is aimed at the KTM690 single-cylinder engine in the Formula Student China (FSCC) at high temperature and high load. Moreover, it is easy to have problems such as overheating, power drop and bursting, and the cooling system should be optimized and designed. Through the combination of CFD simulation analysis and physical testing, the radiator structure is systematically optimized to achieve the stable operation of the engine in the optimal temperature range of 85-95℃. The research focuses on lightweight radiator design, spatial layout adaptation and reliability verification. The design provides a practical solution for lightweight and efficient heat dissipation for the cooling system of FSCC racing cars.
