摘　　要：为提升再生稻收获机作业时的通过能力,根据再生稻头季收获农艺要求,设计了一种再生稻收获机浮动底盘,采用双均衡全浮动支重轮系,使轮系根据凹凸地形自行调节,车身不会有较剧烈振动,进出田地十分平稳,可以有效地改善再生稻收获机运行的平顺性及提高爬坡越野能力。履带宽度为280 mm,采用全液压底盘,具有较高的灵活性,使用Recurdyn进行虚拟样机仿真分析,结果表明,再生稻收获机浮动底盘转弯灵活,履带最高沉陷量120 mm,爬坡能力符合预期。田间试验表明,再生稻收获机浮动底盘田间转弯灵活,相比普通履带式收获机碾压率降低25%,该研究可为后期再生稻收获机理论研究提供参考。In order to improve the passing capacity of the ratooning rice harvester during operation,a floating chassis of the ratooning rice harvester was designed according to the agronomic requirements of the first harvest season of the ratooning rice.It adopts a double balanced fully floating support wheel system,which adjusts the wheel system according to the uneven terrain without severe vibration of the vehicle body.It is very smooth when entering and exiting the field,effectively improving the smoothness of the operation of the ratooning rice harvester and enhancing its off-road climbing ability.The track width is 280 mm and adopts a fully hydraulic chassis with high flexibility.The virtual prototype simulation analysis with Recurdyn shows that the floating chassis of the ratooning rice harvester has flexible turning,the maximum settlement of the track is 120 mm,and the climbing ability meets expectations.Field experiments have shown that the floating chassis of the ratooning rice harvester has flexible turning in the field,reducing the rolling rate by 25%compared with ordinary tracked harvesters.This study can provide reference for theoretical research on ratooning rice harvesters in the later stage.
