| 摘 要： | 针对第一代样机在试验过程中出现的松土爪拱土和整机抖动现象，对松土爪的运动轨迹进行了研究，探明了拱土的原因。依据松土爪运动规律的分析，找出影响其作业性能的关键结构参数，对松土机构进行了改进设计。在ADAMS系统环境下，进行了虚拟建模和运动学仿真试验，优化样机技术参数，完成了第二代样机的试制与试验。试验结果表明，第二代样机不仅有效地克服了因松土爪拱土而引起的整机抖动，且各项作业指标也达到了松土机具的设计要求。 |

| Abstract: | Aimed at the phenomena of tillage claw arching soil and the whole machine shaking in the course of experimentation for the first-generation prototype, the moving trajectory of the tillage claws was studied and the causes for the phenomenon of soil being arched were found out. Structure of the claw scarifier was improved, based on discussion on the movement disciplinarian of the tillage claws, the key structural parameters that influenced its performance were found out, and were set as variables. In the environment of ADAMS system, virtual model was built and kinematics simulation experiments were done. Through analysis on the simulation results, technical parameters of the prototype were optimized, and second-generation prototype was made while experiments were done. The results showed that the second-generation prototype overcame effectively the problem of the machine shaking because of claws arching soil, and all other indicators reached the technical requirements of tillage equipment. |
