为了降低悬点动载荷对抽油机系统的不利影响研究设计一减振悬绳器。通过ADMAS多体动力学仿真软件,对室内抽油机仿真平台在悬绳器上施加金属橡胶干摩擦阻尼元件前后进行仿真分析,获得了金属橡胶元件作用在抽油机悬绳器上对抽油机的动载荷具有明显的拟制作用,利用室内抽油机实验平台,结果显示:上冲程中悬点动载荷可降低10%以上,下冲程过程中动载荷增加值可达5%左右。为金属橡胶悬绳器在工程实际中的应用奠定了理论和试验基础。
In order to reduce the negative impact of dynamic load on the pumping system, a damping suspension wire rope was designed. Through ADMAS multi-body dynamics simulation software, simulation analysis was performed before and after applying metal rubber dry friction damping element on suspension rope to the simulation platform of indoor pumping unit, and the effect of metal rubber element on the oil pumping machine suspension rope was obtained. The dynamic load of the machine has obvious fictional effect. Using the experimental platform of indoor pumping unit, the results show that the dynamic load can be reduced by more than 10% in the upper stroke and the increase of dynamic load in the lower stroke by 5%. It has laid a theoretical and experimental foundation for the application of metal rubber suspension rope in engineering practice.
