无阻尼动力减振器,由于它结构简单,有较好的应用价值,但它使用的频带太窄,限制了它的应用,使设计也往往不成功。本文论述如何根据“减振区域图”确定无阻尼动力减振器的适用范围,并编制计算程序,用人机对话的方式在电子计算机上运算,使它的设计迅速、合理。 Undamped dynamic shock absorber, because of its simple structure, has a good application value, but its use of the band is too narrow, limiting its application, so that the design is often unsuccessful. This article discusses how to determine the applicable range of an undamped dynamic damper based on the “damper area map” and compiles the calculation program. It is calculated on a computer by means of human-machine dialogue, making its design rapid and reasonable.
