The peak particle velocity (PPV) is one of main indicators for determining the extent of ground vibration. Owing to the complexity of blasting process, there is controversy over which parameters will be considered as the inputs for empirical equations and machine learning (ML) algorithms. ...
很多论文中提到的监测peak particle velocity (PPV),具体在history中如何查看?LS-PrePost LS-DYNA 请问各位大佬,用 hypermesh 做静力学分析时,怎么在 3D 单元的表面生成一层壳单元,生成后需要设置哪些参数(壳单元用于后续的疲劳分析)? ABAQUS计算集中力作用在轨道上时,产生的位移过大 关注问题 邀请回答 我来回答 ...
1) peak particle velocity 峰值粒子速度 2) peak velocity 峰值速度 1. In this paper, a method, which synthesizes the artificial ground motion compatible with the specified peak velocity as well as the target acceleration response spectrum, was proposed. 提出一种以绝对加速度反应谱和峰值速度为...

On the basis of analysis of datum from monitoring the ground vibration of bench blasting near a running nuclear power plant,a neural network model has been developed to predict the peak particle acceleration amplitude of blasting vibration.Comparing the results calculated in empirical formula with the...
On the basis of the analysis of the theory of the cylindrically elastic wave,the theory of the seed wave induced by a long cylindrical charge and the Heelan Solution for stress wave field induced by a short cylindrical charge,a new equation for the attenuation of the Peak Particle Velocity (...
