摘要
航天器上的一些展开机构采用了弹性元件为动力源。当其展开到位时,通常会对与之相连的部件产生冲击。加装阻尼器是抑制这种冲击的有效措施之一。丈章介绍了航天器展开机构常用转动型阻尼器的类型、工作原理及特点,并对相关技术的发展和应用作了分析和评述,提出了开展黏滞阻尼器研究的建议,并指出了研究中应考虑的问题。
Elastic components are often used as the drive for spacecraft deployment mechansin.When a certain mechanism is completely deployed,impaet loads are usually applied on its adjaeent components.Applieation of dampers is one of the effective approaches to suppress such impaet loads.The type,the operation principle and the characteristics of rotary dampers for spacecraft deployment meehanism are diseussed.The development and the applieations of the related techniques are analyzed.It is suggested that viseous dampers be paid more attention in China than other kinds of dampers Related problems are Pointed out
