摘要

介绍基于杆系机构原理的径向整体开合屋盖结构，分析其组成、可展机理及运动特点。基于多体动力学原理，运用ANSYS及ADAMS对径向整体开合屋盖结构的运动全过程进行精细化联合仿真分析。系统考察固定屋盖刚度、轮轨间摩擦系数、轮轨间隙等参数对活动屋盖运动中固定屋盖及活动屋盖挠度、驱动力、活动屋盖连杆弯矩等指标影响。结果表明，固定屋盖刚度对闭合状态下屋盖挠度影响较大，对展开状态下屋盖挠度基本无影响；驱动力随摩擦系数增大、轮轨间隙减小而增大；各响应指标的动力现象普遍存在，波动幅度大小与摩擦系数及轮轨间隙呈正相关趋势。相关结论可为开合屋盖设计提供依据。

Abstract

A class of radial retractable roof system that is based on bar structures is introduced. The structural components, deployable mechanism, and its motion features are analyzed. Based on the theory of multi body dynamic method, we apply a co-simulation method of ADAMS and ANSYS to simulate the motion of the radial retractable roof structure. We also examine the impacts of parameters such as the stiffness of the fixed roof, wheel-track friction coefficient, wheel-track clearance, and the roof velocity on the roof’s moving process. The impacts were measured by indicators such as the deflection, driving force, and bending moment of links. It is found that the stiffness of fixed roof had a great influence on the roof deflection under the closed state, while minimal effect under the expansion state. With the increase of friction coefficient and decrease of wheel-track clearance, the driving force increased. The dynamic phenomena of structural behavior are universal existence. The fluctuating range of response curves appeared positive correlation with the friction coefficient and the wheel-track clearance. The conclusions could be provided for the design of deployable roof structure in future.
