摘　　要：为提高半喂入式花生联合收获机作业效率,改善其适应性,以前进速度、夹持输送速度、摘果辊转速为试验因素,以损失率和破碎率为试验指标,采用三因素二次回归正交旋转组合试验设计方案,运用Design-Expert 8.0.6软件进行响应面分析,得到响应面模型;对所得到的数学模型进行优化求解,并采用优化后的最佳工作参数组合进行验证试验。结果表明:当前进速度范围为1.0~1.3m/s、夹持输送速度工作范围为1.2~1.6m/s、摘果转速为450、600r/min时,损失率和破碎率均满足作业标准。In order to further improve the operation effectiveness of Semi-feeding Peanut Combine Harvester,three factors and two levels regression orthogonal rotation combination design experiment was done under the condition that forward velocity,gripping delivery velocity,and fruit-picking revolving velocity were made as experiment factors,and loss rate and broken rate were made as experiment indicators. Mathematical model of RSM was built and optimized by using the Design Expert 8. 0. 6 software. Verification experiment was done by using the optimal parameters combination after optimization. The experiment results showed that loss rate and broken rate meet the operation standard when forward velocity was 1. 0-1. 3m/s,gripping delivery velocity was 1. 2-1. 6 m/s,fruit-picking revolving velocity was 450 and 600r/min.
