摘要: 本文就年轮型高压装置,对福长修的平板模型作了改进,即在式中引入了压砧的半顶角,计算了封垫中的压力及封垫对于压砧的支撑力,计算结果基本上和实验结果符合。就年轮型及立方六面顶型高压装置讨论了高压室和封垫的压力增量之间的匹配问题,还就卸压问题介绍了Murnaghan方程的应用。

Abstract: For the belt type high pressure apparatus, this paper has improved the flat model of O. Fukunaga by introducing the half-angle of the tapered anvil and calculated the pressure in the gasket as well as the supporting force of the gasket to the anvil. The calculated results agree with the experimental results quite satisfactorily. The matching between the pressure increments of gasket and pressure cell has been discussed for both belt type and cube type high pressure apparatus. This paper also explained how Murnaghan equation could be used to solve the problem connected with the unloading. -
