Behavioral Analysis of Hydraulically Driven Fire Fighting Water Monitor Trailer Subjected to Type of Fire Ways of Its Fire Protection

摘要

When a place catches fire it is well observed fact that a large amount of time is wasted by the fire man to extinguish fire due to huge distance present between the place of the fire and the water hose or water monitor.Because of which large amount of water is wasted due to evaporation of water loss during jet impact.It is impossible to take water monitor close to fire because of high temperature.Hence,an effective fire fighting can not be done there as it requires delivery of water at right time,right place and in adequate quantity.To reduce the distance present in between water and place of the fire a new method of fire fighting by the use of hydraulically driven vehicle is developed by Prof.PRASHANT S.KADU under the guidance of Dr.H.T.THORAT.The vehicle uses the pressurized water from the pump to move forward taking into account the property of straitening,elongation and buckling of hose.When the water is pumped,then pushing force developed due to straightening property of the fire hose is used to move the vehicle.This paper presents the study of behavior of the steel subjected to fire and effect of fire on the mechanical properties of the trailer.The response of the trailer which includes stress distribution and displacements under various loading conditions are to be observed.The method used in the numerical analysis is finite element technique using Ansys software.The result shows that the stresses developed lie within the range and ensure infinite life.Ways of fire protection of steel are also suggested to increase the time spend inside the fire without affecting the properties of the steel.
