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悬臂梁的动态特性,建立其动力方程。
By means of time scales, this paper established some oscillation theorems for the second-order nonlinear delay dynamic equation on time scales. 摘要借助时间尺度的有关理论,研究了一类二阶非线性时滞动力方程解的振动性。
