摘要
消防机器人在火灾处置中的应用越来越广泛,降低了消防员在火灾救援中的风险,同时也带来了研究其热防护性能的需求.本文以某履带消防机器人底盘车身为研究对象,以保护其内部电子元器件不受高温损害为目的,以火场环境为条件,对车身温度场分布规律进行了分析.基于消防机器人底盘车身热防护结构材料的正交试验设计,使用ANSYS Workbench软件对不同热障涂层材料、基体材料和隔热保温材料组合的热防护性能进行分析,提出了车身热防护结构最优组合方案.在确保消防机器人热防护性能的前提下,采用响应面优化分析对热障涂层厚度和隔热保温层厚度进行优化,热障涂层厚度、隔热保温层厚度分别减少了3.4、4.2 mm,底盘车身内部体积扩大了11.74%,质量减小了15.83%.
Abstract
The more and more extensive application of firefighting robots in fire disposal reduces the risk of firefighters in fire rescue,and also brings the demand for high temperature resistance and thermal protection technology.This paper takes the chassis body of a tracked fire fighting robot as the research object,in order to protect its internal electronic components from high temperature damage,and analyzes the distribution law of the body tempera-ture field under the condition of fire field.Based on the orthogonal test design of the thermal protection structural materials of the fire robot chassis,the thermal protection performance of the combina-tion of different thermal barrier coating materials,base materials and thermal insulation materials was analyzed by using ANSYS Workbench software,and the optimal combination scheme of the thermal protection structure was proposed.On the premise of en-suring the thermal protection performance of the firefighting ro-bot,response surface optimization analysis was used to optimize the thickness of thermal barrier coating and thermal insulation layer.The thickness of thermal barrier coating and thermal insula-tion layer were reduced by 3.4 mm and 4 mm respectively.The in-ternal volume of the chassis body was expanded by 11.74%and the mass was reduced by 15.83%.
