脉动流诱发有附着物的板振分析

Vibration analysis of slab with adhesions underpulsating flow inducement

利用压气机与脉动流发生装置,变流体成脉动流注入到工程中的板壳结构上,使其固体结构部分在脉动流的作用下产生强迫振动,这对工业上分离板壳结构表面固体附着物很有实际意义,以薄板为研究对象,导出了薄板横向振动即弯曲振动微分方程,并着重从理论上分析了分离其上的固体附着物的条件及其各种影响因素。

By making use of an air-compressor and making pulsating plow equipment to change a kind of fluid into pulsating flow and then injecting the pulsating flow into a blate-cass structure the part of solid structure will produce compel vibration. The method has a practical meaning to solve the relative problem about separating the solid adhesion or attachment and aspirating on the surface of the structure. In this paper, thin slab is studied. The differential equation of lateral vibration has been derived. The separating conditions and influence factors on solid adhesion or attachment separating are theoretically analyzed.
