本文设计了一种适合HN4GDL-132型切段式甘蔗联合收割机作业使用的履带底盘，依据行走系统所承受的行驶阻力，经负载分析，确定履带底盘主要性能指标，确定液压传动系统相关参数选取液压元件，并制造样机进行田间试验，测试收割机液压系统参数在前进工作、后退和空车3种工况下的变化。试验结果表明，收割机匀速作业时，行走系统流量和压力稳定，行驶速度约为0.507 m/s，消耗功率小于10 kW，小于预定值，行走系统能满足收割机的工作要求，试验结果为履带式甘蔗收割机行走系统的使用和改进提供参考。%The technology mechanized harvesting is a key of cane industrial growth. Development of self-propelled sugarcane harvester is a new way to solve disadvantages by direct mounted harvester. However, the driving system must be meet requirements of other parts in harvester, and it must be low speed, high torque, less power and it running stable. The performance of driving system has some effect on efficiency of harvester directly. Therefore, design the driving system for harvest is meaningfulness on the development of sugarcane harvester. This article made field test of sugarcane harvester. Measurement of hydraulic parameters when the harvester forward work and backed off and empty ran in test. The test result is close to theoretical analysis, so the state-space model of driving system is corrected. When harvester works at driving speed of 0.507 m/s, the flow and pressure of hydraulic system is stable. Therefore, the drive system is appropriated for sugarcane harvester.
