摘要

为解决非平稳随机循环载荷等不确定性因素造成的变速离合器接合过程平稳性问题

提出了面向离合器接合过程控制的不确定性估计方法。以某5 t装载机V型工况重载后退作业离合器接合过程为研究对象

通过对其扭转振动方程降阶处理

在构建非平稳随机循环载荷不确定项参数表达与离合器接合摩擦转矩时变模型的基础上

得到离合器接合过程主从动端转速差的不确定性表达。通过变速器参数标定、台架试验及数值仿真

结果表明该方法可实现离合器接合平稳特性分析及不确定项阈值估计。所提出的不确定性估计方法对类似强不确定性离合器接合的鲁棒控制器设计具有参考价值。

Abstract

To solve the problem of clutch engagement smoothness caused by uncertain factors such as non-stationary random cyclic load

a method for estimating the uncertainty of the clutch engagement process control is proposed. Taking the clutch engagement process of heavy load reverse operation of a 5 t loader under V-type working condition as the research object

the uncertainty expression of the speed difference between the driving and driven ends of the clutch engagement is obtained by reducing the order of the torsional vibration equation of the clutch engagement process and on the basis of constructing the parameter expression of non-stationary random cyclic load uncertainty and the time-varying model of clutch engagement friction torque. Transmission parameter calibration

bench test and numerical simulation are conducted

and the results show that the method can reali-e the analysis of clutch engagement smoothness and the uncertainty threshold estimation. The uncertainty estimation metho
