Fluid Simulation Inside High Pressure Cleaning Tanker And Tank Structure Optimization

With the continuous expansion of urban construction,the urban cleaning demand increases,and the high-pressure cleaning car is used as a functional and efficient clean sanitation car,and the use of urban road cleaning is more and more.The main part of the high-pressure cleaning vehicle is a tank,stores a large amount of water,during the driving process,due to bumps,vehicle braking,etc.,the water in the can often swayed,especially when the vehicle encounters special circumstances emergency brakes,water is The inertial action will produce a huge impact to the tank head and the like,so that the can be destroyed.In order to inhibit the shake of water in the can,reduce the impact force of the canopy before and after the can,and the practice is usually taken to mount several panels laterally in the tank.However,structural failure may also occur when the airborne board is affected by water.In the actual use of high-pressure cleaning vehicles,the situation of cracking between the wave baffle and the tank is repeated,and the cost of repair and use is increased.Once the wave baffle is falling off,it is not only possible to protect the effects of protecting the can,but also damage to the tank structure and internal pipelines.Through the study of water fluid in cannas,the force of the tank is analyzed,and it is possible to explore the factors that affect the use of the wave baffle.According to these factors,the form of the wave baffle is improved,and the risk stress position of the tank is optimized.Make the tank structure to meet the requirements.At the same time,the liquid shake problem solution for transporting liquefied natural gas,oil and other liquid tankers and vessels have also provided a reference.Therefore,this topic has important research significance and practical value.This paper uses high-pressure cleaning tanker as research objects,and the effect of the longitudinal impact of the fluid on the structure of the tank.On the basis of reviewing a large number of relevant literature and research,the method of numerical simulation and structural simulation.Firstly,the fluid model is established,and the corresponding Fluent solution parameter setting is performed,and the motion state of the fluid in the tank is analyzed when the tanker is at deceleration under various working conditions,and the pressure distribution of different moments in the tank is analyzed.It mainly studies the size of the tank by the water and the size of the hydrodynamic impact force and the change in water when the water loaded different depths is loaded.At the same time,it is selected to analyze the quantity of the panel installation,the opening method of the wave baffle,the surface shape of the wave baffle,demonstrate that the wave baffle has a good effect on suppressing the shake of the liquid,and the factors are obtained for the panel The impact of performance generation.Second,the tank finite element model is established with ANSYS,and the load of the fluid calculation output is loaded into the tank structure by the parameterized language command to obtain a solid state in which the tank structure under different conditions is obtained.The calculation results indicate that the tanker is in the case where the impact of the water fluid is mainly concentrated on the palette and front sealing plate when the shock of the water flow is slow.According to the calculation result,the integral analysis of the force is analyzed,and the key component structure such as the panel and the front sealing plate is analyzed,and the structural optimization of the cleaning vehicle tank,including the panel structure,opening position,sealing structure.And improvements in light quantization.Through structural optimization,the stress of the whole vehicle is significantly reduced,and the material yield strength requirements are met.The quality of the tank has greatly reduced,and it has been lighter,and it has achieved a good effect,which provides a reference for the optimization direction of the liquid tank.The calculation of the tank is consistent with the actual damage position and verifies the effectiveness of the simulation.
