摘　　要：某自行火炮中传统抽气装置的喷嘴极易锈蚀、拆解更换难且部件重量大,造成火炮起落部分重量较大。针对这一问题,采用钛合金新材料及喷孔代替喷嘴,对传统抽气装置进行优化改进。通过建立抽气装置的虚拟样机,材料分别采用合金钢和钛合金进行最大压力工况下的对比分析计算,确定新材料新结构的理论可靠性。经过射击试验考核,新方案满足抽气装置的使用要求,装置质量减少了30%,耐腐蚀性能、维修性和产品质量得到极大提高。In response to the traditional air extraction device in a certain self-propelled gun,the spray nozzle is prone to rusting,difficult to disassembly and replace,and the weight of the components is large,resulting in a heavy weight of the gun′s take-off and landing parts.A new titanium alloy material is used to optimize and improve the traditional air extraction device by replacing the nozzle with nozzle holes.By establishing a virtual prototype of the air extraction device and conducing comparative analysis and calculation under maximum pressure conditions using steel alloy and titanium alloy materials respectively,the theoretical reliability of the new material and structure is determined.After shooting tests and assessments,the new plan meets the functional requirements of the air extraction device,reduces the weight of the device by 30%,and greatly improves corrosion resistance,maintainability and product quality.
