协调器小平衡机失稳校核及设计

为进一步研究协调器小平衡机机械特性,分析小平衡机活塞杆的稳定性及其设计位置对整机性能的影响。以多体动力学及虚拟样机技术为基础,在ADAMS环境里建立小平衡机的虚拟样机模型。利用该模型对小平衡机活塞杆进行受力分析和压杆稳定校核,并分析了小平衡机的位置改变对协调器驱动力矩的影响。仿真结果证明:该方法能确定位置变化量与最大力矩之间的关系,为小平衡机的压杆稳定研究提供数据依据。

Instability Check and Design on Equilibrator of Coordinator

In order to study the mechanical features of the equilibrator of coordinator in the further,the influences on performance of the machine caused by the stability of piston rod and the position of equilibrator are studied.Based on multi-body system dynamics and virtual prototype technology,virtual prototype model is established by means of ADAMS software.Taking advantage of the model,force analysis and check of instability are performed on piston rod of equilibrator and the influence on torque of coordinator caused by change of equilibrator＇s position is studied.The simulation results indicate that the method determines the relation between the change of position and the max torque and results supply data basis for the stability study on equilibrator.
