微型智能消防车结构设计与仿真分析

Structural Design and Simulation Analysis of Mini Intelligent Fire Engine

为解决社区、学校等人员密集场所发生火灾时,大型消防车因道路狭窄、交通拥堵等原因无法及时抵达火灾现场以及消防栓个数不足的问题,设计出一种具有多个喷射水枪的微型智能消防车。首先结合模块化理念进行微型智能消防车的结构和功能设计;然后利用Lame公式对转换水箱管道作理论计算,Ansys Workbench对简化三维模型进行静力学分析,比对理论计算与仿真数据。最后通过比较不同结构和材料在不同压力工况下转换水箱的仿真结果,得出最优设计方案。结果表明:转换水箱管道的理论计算与仿真结果基本一致,应选择肋板式结构和光敏树脂材料为最优方案。该设计有助于破解远水难解近渴的难题,实现安全就在百姓身边的愿景。

In order to solve the problem that large fire engines can’t arrive at the fire scene timely due to narrow roads,traffic congestion and the number of fire hydrants is insufficient when the community,school and other crowded places have a fire,a kind of mini intelligent fire engine with multiple squirt guns is designed.Firstly,the structure and function design of the mini intelligent fire engine is combined with the modular concept.Secondly,the theoretical calculation for the pipe of conversion water tank is made by Lame formula and the static analysis of the simplified 3 D model is carried out using Ansys Workbench so as to make a comparison of theoretical calculation and simulation data.Lastly,the optimal design scheme is obtained through comparing the simulation results of conversion water tank with different structures and materials under different pressure conditions.The results indicate that the theoretical calculation of the pipe of conversion water tank is basically consistent with the simulation results.Ribbed slab structure and photosensitive resin material should be selected as the optimal scheme.This design will be helpful to solve the problem that a slow remedy can’t meet an emergency and realize the vision that security is all around.
