针对提高炸药配方的固体含量会影响浇注的问题，根据理论分析、机械系统3 维模型构建与客户实际需 求对真空振动浇注系统进行优化设计。对系统进行分析，并从偏心块设计、电机功率选型以及振幅等进行设计。在 浇注工序上采用机械振动，系统最大振幅2 mm，参振物质量4 000 kg，振动用电频率20～30 Hz，真空度小于等于 3 kPa。实际应用结果证明：该系统能提高产品密度及产品合格率，缩短浇注周期。产品经CT 探伤检测，无明显瑕 疵和气泡，产品合格率100%。
Aiming at the problem that increasing the solid content of explosive will making influence on casting, according to theoretical analysis, three-dimensional model construction of mechanical system and customer’s actual needs, the vacuum vibration casting system is optimized. The system is analyzed and designed from eccentric block design, motor power selection and amplitude. Mechanical vibration is used in casting process. The maximum amplitude of the system is 2 mm, the mass of the vibrator is 4 000 kg, the vibration electric frequency is 20-30 Hz, the vacuum degree is less than 3 kPa. The application results show that the system can improve product density, improve product eligibility and shorten the casting cycle. The product was detected by CT without obvious flaws and bubbles, and the product acceptance is 100 %.
