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...
4) PeakParticle Velocity 点峰值振动速度5) myocardial wall velocity 室壁运动速度6) Upper wall tissue velocities 前壁运动速度补充资料:速度瞬心 在刚体平面运动中,只要刚体上任一平行于某固定平面的截面图形S(或其延伸)在任何瞬时的角速度ω不为零,就必有速度为零的一点P′,称为速度瞬心。在该瞬时,就...
aSuch uncertainties need to be quantified by appropriate probability distributions for having better confidence in the predicted peak particle velocity levels. 这样不确定性需要由适当的概率分布定量为有更好的信心在被预言的高峰粒子速度水平。 [translate] ...

Vibration and Overpressure observation data can now be recorded in BlastLogic by monitoring location as well as the measured maximum instantaneous charge, peak particle velocity and decibels. Los datos de observación de vibración y sobrepresión ahora se pueden registrar en BlastLogic monitoreando ...
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 ...
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 (...
