Φ1米高超声速风洞自主式维修保障系统设计

为了解决Φ1米量级高超声速风洞装备试修矛盾,提高风洞参试效率并拓展风洞技术性能,实现风洞装备管理信息化和过程质量控制精细化,满足国家高超声速武器装备和航天飞行器研制中地面试验的需求,提出了建设Φ1米量级高超声速风洞自主式维修保障系统。文章分析了风洞的设备组成、运行方式、试验任务特点以及风洞装备维修保障的现状,按照“增强的基于状态维修”的装备保障新模式,进行了系统设计架构,明确了硬件系统组成和软件各模块的功能。对风洞装备故障模式分析、基于振动特性分析的诊断和测试技术、基于应变特性分析的诊断和测试技术等关键性问题进行了实验探索与验证。     

A deep learning method based on prior knowledge with dual training for solving FPK equation

The evolution of the probability density function of a stochastic dynamical system over time can be described by a Fokker–Planck–Kolmogorov(FPK) equation, the solution of which determines the distribution of macroscopic variables in the stochastic dynamic system. Traditional methods for solving these equations often struggle with computational efficiency and scalability, particularly in high-dimensional contexts. To address these challenges, this paper proposes a novel deep learning method based...
