摘 要: 运用直角坐标下的几何非线性热弹耦合振动基本方程 ,对周边固支、简支圆板运用伽辽金法求解 ,得出振幅随时间变化的数值解。比较了不同热弹耦合参数对应的振动情况 。 Using the fundamental equations of nonlinear thermoelastic vibrations,the clamped and simply supported circular plate is analyzed.A system of nonlinear differential equation about time is obtained by Galerkin′s method.The vibration states with different thermoelastic coefficients are compared and the effect of thermoelastic coupling on the amplitude and frequency is presented.
