【摘要】 为保证采棉机动力换挡过程中动力输出的连续性，以多个离合器为研究对象，提出区域交叉控制策略，设计采棉机动力换挡传动方案及换挡液压系统，分析并搭建采棉机液压传动系统模型，分析离合器、制动器、马达、行车速度与其电磁阀阀芯位移量响应情况。试验结果表明：采棉机速度曲线平滑上升，换挡过程无动力中断，无明显动力换挡冲击，验证了策略的有效性。更多还原

【Abstract】 In order to ensure the continuity of power output during the power shift process of cotton picker, a regional cross-control strategy was proposed with multiple clutches as the research object.The power shift transmission scheme and shift hydraulic system of cotton picker were designed.The hydraulic transmission system model of cotton picker was analyzed and built.The response of clutch, brake, motor, driving speed and displacement of solenoid valve spool was analyzed.The test results show that the speed curve of the cotton picker rises smoothly, there is no power interruption during the shift process, and there is no obvious power shift impact, which verifies the effectiveness of the strategy.更多还原
