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.
