带药型罩药柱压制安全性

为满足药柱压制安全性要求,对药柱压制的参数进行安全性分析和改进.采用500 t双向液压机进行带药型罩主药柱压制,通过对比常用产品压制的应力仿真结果,对产品A进行仿真分析,提出改进措施,并通过实际验证.结果表明:优化后的A产品压制过程,通过调节压制参数,降低局部炸药的压制应力,提高了药柱压制的安全性.该研究可作为一般带药型罩主药柱压药安全性分析的一种有效途径,能评定和改进压药过程的安全性.

Pressing Safety of Grain with Liner

To meet safety requirement of grain pressing, this paper analyzes the safety of parameters for grain pressing and makes some improvement on it. Research on pressing main grain with liner by 500t bidirectional oil press, by comparing with common product pressing stress simulation result, carry out simulation analysis for product A and give improvement suggestion and verify it by practice. The result shows that the optimized pressing process of product A has improved safety of grain pressing by adjusting pressing parameters and decreasing the pressing stress of partial explosive. This study can be taken as an effective way for analyzing the pressing safety of ordinary main grain with liner, evaluating and improving the safety of pressing process.
