摘要:
针对目前爆炸硬化所用炸药的性能不足,研制出一种高聚物粘结塑性炸药,利用该塑性炸药对高锰钢辙叉进行爆炸硬化。试验表明,经过该炸药表面硬化后的高锰钢辙叉,在铸造基体硬度为HB170~190时,一次硬化后,表面硬度达到HB260~280;两次硬化后,表面硬度达到HB310~330。并进一步结合金相分析,探讨当前国内在高锰钢爆炸硬化中硬度测量方面存在的问题。最后,运用动力有限元软件对高锰钢爆炸硬化工艺过程进行了数值模拟,模拟结果与实验情况基本吻合。
Abstract:
For the shortages of explosives used on explosive hardening at present, a new polymer bonded plastic explosive is developed. The explosive hardening experiments on Hadfield steel of rail frogs show that the hardness on the surface of rail frogs can reach from HB170~190 to HB260~280 by hardened one time and to HB310~330 by hardened two times. Hardness measurements of explosive hardening on Hadfiled steel are discussed based on metallography analysis. At last, the explosive hardening is simulated by Lsdyna, and the numerical results are generally consistent with experiment results.
