摘要
在分析振动对集装箱检测车系统性能影响的基础上 ,提出了 6 0 Co集装箱检测车悬臂的振动指标。为了验证悬臂结构的强度和刚度条件 ,采用动力学分析软件 AL GOR计算了 6 0 Co集装箱检测车悬臂的静态变形、振形和固有频率。悬臂在启动加速过程中振动最大 ,通过给悬臂施加一个与启动加速度相当的惯性力的方法 ,非常简单地模拟了启动加速过程 ,数值计算结果与实际测试结果较吻合 。
The cantilever vibration criterion for the 60 Co container inspection vehicle was analyzed based on the relationship between vibration and the performance of the container inspection system. Static deformation, the vibration shape and the inherent frequency of the cantilever of the 60 Co container inspection vehicle were calculated with the ALGOR Finite Element System to verify the strength and rigidity of the cantilever. The cantilever vibration amplitude will achieve its maximum value at the start of its accelerating process. This process was easily simulated by imposing an inertial force on the cantilever. The predictions agree well with the test results indicating that this kind of finite element model of the cantilever structure is capable of capturing the mechanical characteristics.
