摘　　要：自走式单行水稻硬质秧盘起盘机中拨齿辊对起盘作业的质量有重要影响。为避免作业过程中出现拨齿辊结构强度不足和共振问题,运用NX12.0软件建立单行起盘机的三维模型,将拨齿辊模型简化后导入ANSYS Workbench软件,并对其分别进行静力学和模态分析。静力学分析结果表明:拨齿辊在静载荷下最大位移为0.029 615 mm、最大应力为12.292 MPa,小于拨齿辊材料Q235钢的屈服强度极限。用Design-Expert 12.0软件对3个因素的回归方程优化求解,结果表明:起盘机拨齿辊转速为30 r/min、前进速度为1.2 km/h、拨齿辊高度为10 mm。为了检验田间实际情况下自走式水稻硬质秧盘起盘机的起盘性能,对其进行验证性试验,结果表明:起盘效率平均值为343盘/h,秧盘完整率平均值为97%,卡盘率平均值为1%,满足硬质秧盘起盘的农艺要求。The self-taken one-line rice hard seedlings starting machine has an important impact on the quality of the disk operation.In order to avoid insufficient structural strength and resonance during the operation,used the NX12.0 software to set the three-dimensional model,simplified the gear shifting roller model,and imported the ANSYS Workbench software,and performed static and modal analysis,respectively.The results of static analysis showed that the maximum displacement of the gear shifting roller under the static load was 0.029615 mm,the maximum stress was 12.292 MPa,which was smaller than the yield strength limit material Q235.Used Design-Expert 12.0 software to optimize the resolution of the regression equation of the three factors.The results showed that the speed of the tooth roller roller was 30 r/min,the forward speed was 1.2 km/h,and the height of the gear shifting roller was 10 mm.In order to test the effects of the starting disk performance of self-watched rice hard seedlings from the actual situation of the field,it conducted verification tests on it.The test results showed that the average efficiency of the starting disk was 343 disks/h,the average value of the seedlings of the seedlings was 97%,and the average chuck rate was 1%,which met the agricultural requirements of the hard seedlings.
