摘要

目的针对某大功率船用湿式多片离合器在接排过程中瞬态温度场分布规律不明确的问题,系统研究摩擦副在瞬态工况下的温度场演化机制。方法构建湿式多片离合器接排动力学模型与热分析模型,综合考虑摩擦接触、热弹变形等边界条件,采用热固耦合有限元方法,分析接排过程中摩擦副温度场的分布规律,以及不同接排转速对接排过程瞬时温度场的影响。结果摩擦副温度在接排过程中沿轴向自左至右呈逐渐降低趋势,高温区域集中分布于第二副对偶钢片与摩擦片的摩擦表面。在360 r/min接排转速下,摩擦片最高温度随时间先升高后下降,约在2 s时达到最大值329 ℃。对偶钢片在接排过程中呈现显著的非均匀温度场,高温区域集中分布于摩擦面内外径边缘,最高温度分别达到203 ℃与214 ℃。接排完成阶段,摩擦副最高温度随接排转速的提高明显上升,摩擦面径向温度也逐步升高。结论研究所建立的热固耦合模型能有效表征摩擦副接排阶段的热特性,可为离合器热可靠性设计提供参考。

Abstract

The work aims to systematically investigate the evolution mechanism of the temperature field of friction pairs under transient conditions, addressing the unclear distribution law of the transient temperature field during the engagement process of a high-power marine wet multi-disc clutch. A dynamic model and a thermal analysis model for the engagement of the wet multi-disc clutch were established. Considering boundary conditions such as frictional contact and thermoelastic deformation, the thermo-structural coupling finite element method was adopted to investigate the distribution regularity of the temperature field for the friction pairs in the engagement process and the effect of different engagement speed on the transient temperature field. The temperature of the friction pairs gradually decreased from left to right along the axial direction during the en-gagement process, and the high-temperature region was concentrated on the friction surface between the second pair of dual steel plates and the friction plates. At the engagement speed of 360 r/min, the maximum temperature of the friction plates firstly increased and then decreased with time, reaching a peak of 329 ℃ at approximately 2 s. The dual steel plates exhibited a significant non-uniform temperature field during the engagement process, with high-temperature regions concentrated at the inner and outer diameter edges of the friction surface, and the maximum temperatures reached 203 ℃ and 214 ℃, respectively. In the engagement completion stage, the maximum temperature of the friction pairs increased significantly with the increase of the engagement speed, and the radial temperature of the friction surface also increased gradually. The thermo-structural coupling model established in this work can effectively represent the thermal behaviors of the friction pairs during the engagement stage, and it can provide a reference for the thermal reliability design of the clutch.
