Dynamic Prediction Method for Valuable Spare Parts Demand in Weaponry Equipment Based on Data Perception

Missile is an important weapon system of the army.The spare parts of missile equipment are significant effect on military operations.In order to improve the mission completion rate of missile equipment in wartime,this paper introduces data sensing method to forecast the demand of valuable spare parts of missile equipment dynamically.Firstly,the information related to valuable spare parts of missile equipment was obtained by data sensing,and the sample size was determined by Bernoulli uniform sampling probability.Secondly,according to the data quality of multi-source and multi-modal,the data requirement for dynamic demand prediction of valuable spare parts of missile equipment was obtained.Finally,according to the characteristics of the spare parts,the life of the spare parts was predicted,realizing the dynamic prediction of the demand for valuable spare parts of missile equipment.The results show that the demand of valuable spare parts of missile equipment can be predicted dynamically by using this method,the accuracy is higher than 95%,and the real-time performance is more excellent.

丹霞地貌区公路边坡红层风化机理及其监测技术研究

针对目前红层边坡风化机理及其监测技术方面的研究较少的现状,本文以仁赤高速赤水丹霞区段为依托开展丹霞红层区公路边坡岩体风化机理及检测技术研究并得到以下结论:由于岩性的差异泥岩的崩解速率为由快及慢至稳定,而砂岩的崩解速率为由慢及快至稳定且泥岩的质量损失率要比砂岩高。在日气温恒定条件下,泥岩发生明显的风化崩解,含水量基本恒定时,泥岩风化崩解很缓慢。而砂岩在日气温和含水率基本稳定的条件下,砂岩风化崩解很缓慢。但在反复浸水条件下会加速泥岩和砂岩的风化崩解速率。红层岩体为软质岩,单轴抗压强度不超过30MPa、抗剪强度不超过7MPa且含水率的变化对红层岩体的抗压抗剪强度有着较大的影响。依据泥岩和砂岩的不同特点,建议泥岩风化监测可选取测钉法进行监测,而对于红层砂岩本文建议采用三维激光扫描进行风化监测。通过现场为期一年的测试,效果良好可满足监测需求。
