Abstract

With the development of high energy solid propellants, it is critical to evaluate the safety and power performance of solid propellants in the face of threats such as unmanned aerial vehicles (UAVs) when transporting and using them in contemporary warfare. An electric probe-type cylinder test measured the displacement-time behavior of NEPE high-energy solid propellant, and the parameters of the Jones-Wilkins-Lee (JWL) equation of state (EOS) were derived using particle swarm optimization (PSO) with the Gurney energy model. Further, the parameters of JWL-Miller EOS, determined through AUTODYN simulations, were validated by comparing airburst process simulations with experimental overpressure data. The study established a method for determining EOS parameters of high-energy propellants, achieving a high degree of accuracy. The derived parameters ensure precise modeling of propellant behavior, offering a reliable foundation for future applications in solid rocket motor performance optimization and safety assessment.

基于改进圆筒试验和粒子群优化的高能固体推进剂状态参数方程研究

随着高能固体推进剂的发展，在当代战争中运输和使用固体推进剂时，面对无人机等威胁，对固体推进剂的安全性和动力性能进行评估至关重要。采用电探针式圆筒试验测量了NEPE高能固体推进剂的位移-时间行为，并利用粒子群优化（PSO）和Gurney能量模型推导了JWL状态方程的参数。此外，通过AUTODYN模拟确定的JWL-Miller EOS参数，通过将空爆过程模拟与实验超压数据进行对比验证。该研究建立了一种确定高能推进剂EOS参数的方法，实现了较高的精度。导出的参数保证了推进剂性能的精确建模，为今后在固体火箭发动机性能优化和安全性评估中的应用提供了可靠的基础。
