摘要
研究了二维槽流中矩形板的稳定性问题,采用了伽辽金法解板的运动微分方程,利用傅立叶变换从流体势函数方程得到了扰动压力,采用奇异积分方程法处理流固耦合边界,得出板在不同边界约束下的失稳方式。
It makes a research of the stability of rectangular plate in 2-D groove flow with Garlerkin＇s method solving the board＇s derivative equation, applies Fourier Transform to get the disturbing pressure from fluid potential equation, takes byper-singular integral equation method to process fluid-solid interaction boundary, and gets the instable way of board under the restriction of different boundaries.
