| 针对马铃薯收获机作业时挖掘部件阻力偏大和挖净率低等问题，基于计算机辅助分析。采用Visual Basic 6．0设计建立了牵引阻力模型，对挖掘机构进行运动分析、参数优化和性能分析。计算机模拟试验结果表明：挖净率≥98％，明薯率≥97％，伤薯率≤4％，均达到设计要求。与传统农机设计相比，计算机辅助分析使得计算工作量减少50％，计算精确度高，并解决了农机部件设计试验受气候、土壤类型和种植习惯等条件影响的问题。 |

| Abstract: |
| To solve the key problem of large resistance against and low digging rate of digging parts,A digging components design model was developed with Visual Basic 6.0 by adopting a new designing method computer aided analysis(CAA).Movement analysis,parameter optimization and performance analysis were completed. Computer simulation showed that digging rate was more than 98%,obvious rate more than 97% and damaged rate less than 4.5%.The workload of CAA was only about 50% that of the old method and precision increased.What's more,it avoided the problem that on-the-spot experiment conditions are influenced by climate,soil quality and planting habit. |
