以16kN离心振动台为例,讨论离心机上顺臂安装的电动振动台运动部分受力情况,并以一种常见振动台动圈导向结构为例,重点分析离心振动台动圈导向结构的受力情况。分析结果表明,由于离心力、重力、科里奥利力的共同作用,离心环境振动台运动部分及动圈导向结构受力远大于地面普通振动台,在设计离心振动台导向结构时必须考虑所有力的复合作用,以保证设备及试验的安全性。
Taking a 16kN centrifugal shaker as an example, the force of the moving part of the electric shaker mounted on the upper arm of the centrifuge is discussed. Taking a common dynamic guide structure of the shaker as an example, the stress of the dynamic guide structure of the centrifugal shaker is analyzed emphatically Happening. The results show that due to centrifugal force, gravity and Coriolis force, the motion of centrifugal environment shaking table and dynamic guide structure are far greater than the common ground shaking table. All the forces must be considered in the design of centrifugal vibration table guide structure The compound role, to ensure the safety of equipment and testing.
