Dynamical characteristics of the cantilever beam were analyzed and its dynamical equation was developed by using PEA. 采用有限元分析方法研究懸臂梁的動(dòng)態(tài)特性，建立其動(dòng)力方程。
By means of time scales, this paper established some oscillation theorems for the second-order nonlinear delay dynamic equation on time scales. 摘要借助時(shí)間尺度的有關(guān)理論，研究了一類(lèi)二階非線(xiàn)性時(shí)滯動(dòng)力方程解的振動(dòng)性。
