1.
Based on experimental data of structural response of small samples,support vector machine (SVM) regression method is employed to simulate the nonlinear functional relationship among the peak value of dynamic strain in the cylinder shell,its size and external pulse loading.
在小子样结构响应试验数据样本的基础上,利用支持向量机回归的方法模拟了圆柱壳体动态极限应变峰值同壳体几何尺寸和外加脉冲载荷大小的非线性函数关系,同时通过改进的模拟退火单纯形混合算法优化了支持向量机的性能参数,并将支持向量机回归分析的预测性能同BP人工神经网络方法做了比较,验证了具有优化性能参数组合的支持向量机在小样本条件下更好的预测和推广能力。
2) impulsive loading
脉冲荷载
1.
Under the impulsive loading such as impact and blasting ones, the failure modes of underground defense structures are much more complex than those under nuclear loading, as conventional ductile bending failure can be transformed into brittle shear failure.
在冲击、爆炸等脉冲荷载作用下 ,地下防护结构的破坏形态比核武器作用下的要复杂得多 ,可能由原来的延性弯坏变为脆性剪坏。
3) High impulse load
强脉冲载荷
4) impulsive and concentrated source
集中脉冲荷载
5) cosine pulse loading
余弦脉冲载荷
1.
The software ANSYS/LY-DYNA has been employed to analyze transient dynamic response of a thin-walled conical shell subjected to a cosine pulse loading.
运用有限元分析软件ANSYS/LS-DYNA对在余弦脉冲载荷作用下某圆锥薄壳体的瞬态动力响应过程进行分析,得出了不同时刻下壳体等效应力场的分布,考察了该壳体结构的动强度性能。
6) pulse shape
脉冲载荷形状
1.
Before the experiments to the transient responses of conical shells under impulsive loading, the effect of many factors on the experimental results should be considered, while the pulse shape on the conical shells is one of the important factors.
而所要施加的脉冲载荷形状是要考虑的重要因素之一。
补充资料：脉冲
1.指电流或电压短暂的起伏变化。各种高频脉冲广泛用在无线电技术中。 2.指变化规律类似电脉冲的现象。如脉冲激光器。
