船用湿式多片式离合器改进后接合特性分析
|
摘要
为了进一步对船用湿式多片式离合器的接合特性进行准确分析以及为后续船用离合器优化设计奠定基础,以船用湿式离合器作为研究对象,在等温设计的基础上,通过对接合过程最优压力进行确定和对传统压力分布模型进行改进,得到一种针对湿式多片式船用离合器接合特性的计算方法。分析结果表明:基于最优压力条件下湿式多片离合器主、从动盘角速度达到速度相同时所需时间明显小于线性压力作用,期间产生的滑磨功明显小于线性压力条件产生的滑磨功;采用不同压力分布得到的湿式离合器接合操作力变化存在差异,且修正后的接合操作力始终小于传统模型,接合操作力与接合压力为线性关系;实际湿式离合器有效半径与接合压力之间不存在直接联系,但在计算过程中发现新型压力分布模型始终大于传统模型。
In order to further the engagement characteristics of marine wet multi-plate clutch for accurate analysis and lay the foundation for the subsequent optimal design of marine clutch.Taking the marine wet clutch as the research object,based on the isothermal design,through the engagement process to determine the optimal pressure and improve the traditional pressure distribution model.Finally,a method for calculating the marine wet multi-plate clutch engagement characteristics is obtained.The results indicate that,based on the optimal pressure conditions required time for wet multi-plate clutch driving,driven disk angular velocity reached the speed is significantly less than the linear pressure,and friction work generated in the period is significantly less than the friction work generated by the linear pressure conditions.The wet type clutch-operating force change obtained by using pressure distribution has differences,and the engagement force of the operation after the correction is less than the conventional model,the engagement with the engagement pressure of the operating force is linear.There was no direct link between the actual and the effective radius of the wet clutch engagement pressure,but find that the new pressure is greater than the traditional model of distribution model in the calculation process.
