| 中文摘要: |
| 通过对拖拉机后悬挂式挖坑机弯曲振动的模态分析,找出了需要改进的模态;在分析系统振动各部位能量大小的基础上,查出了结构中的薄弱环节和浪费环节,进而对挖坑机进行了改进设计,其减振结果得到了电测实验验证。 |
| 英文摘要: |
| The models for the bending in the hole diggers rear-mounted on tractors were analyzed to find out the models that needed to be improved; through examining the energy distribution of the vibration system, the weak points and squandering points were confirmed and positioned, and thus the hole digger design was improved with its vibration-control efficacy tested and verified by electromotive experiments. |
