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。

Abstract

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.
