CHARACTERISTICS AND IMPLICATIONS OF BRIEF DURATION HYDRODYNAMIC FORCES IN THE INTERTIDAL ZONE
CHARACTERISTICS BRIEF DURATION HYDRODYNAMIC
2015/11/12
The hydrodynamic forces produced by breaking waves make the rocky intertidal zone
one of the most physical stressful environments on Earth. Although the classical inline hydrodynamic forces, drag an...

多点成形冲头动态接触压力仿真分析(Simulation on Dynamic Contact Forces of Punches in Multi-point Forming Process)
多点成形 冲头 接触压力
2010/12/29
采用弹塑性有限元法,建立多点模具复杂多接触面的力学模型,对不同材料、不同厚度和不同曲率半径的球形件多点对压成形过程进行数值模拟,分析了冲头最大接触压力的变化过程及其影响因素。结果表明:材料的弹性模量和屈服强度越大,成形件的板厚和变形量越大,所需的成形力就越大,所以冲头的接触压力就越大。
阶梯隔舌对离心泵压力脉动和径向力影响的数值模拟(Numerical Simulation on Pressure Fluctuations and Radial Hydraulic Forces in Centrifugal Pump with Step-tongue)
