| 摘 要： | 本文提出一种建立具有非线性边条连续梁动力学模型的方法。该方法侧重研究:(1)非线性边条的分段线性替代;(2)速度不连续模型的建立;(3)不同边条下广义力和初始条件的确定方法。该方法对研究压气机舌形阀片这类问题的动态响应具有重要的参考价值。

| Abstract: | In this paper, an analytical approach is presented to formulate the dynamic model of continuous beams with motion stop. This method involves (1) Replacing the nonlinear boundary conditions by the piecewise linear ones. (2) Formulating the change of velocity due to collision. (3) Evaluating the integral to generate the generalized force and initial conditions. This approach is applicable to handling the impact problems in dynamic analysis of gas compressor valves and others of this nature. |
