摘要
导向装置是可燃毒物组件抓具的设计要点之一,在可燃毒物组件提升和下降过程中,通过联动实现可靠、安全、准确地开合动作,完成导向可燃毒物棒束的功能。传统的设计采用四连杆机构,推杆较长且机构较复杂,本文介绍的导向装置采用直线凸轮与滚子机构,并用三维软件做了相应的运动学和动力学仿真、验证和比较,结果表明,设计改进是合理可行的。
The guiding device, which performs open and close action reliably, safely and accurately in association with the up and down movement of BPA （Burnable Poison Assembly）, is a key point for BPA handling tool design. In a conventional design, four-linkage mechanism is used. However, the pull-link is fairly long and the structure is complicated. In this paper, we propose a new design of the guiding device, where linear cam and roller are used instead. A 3-D simulation study on kinematic and kinetic performance of the new guiding device shows that the design improvement is reasonable and achievable.
