Development And Study Of The Air-cooled Cooling Wheel

Nowadays, the automobile traffic accidents to be too numerous to enumerate causedby tire. Have a count, it is said that the highway traffic accident,46%is due to tiremalfunction, which burst alone accounted for more than70%of the total accident, alongthe flat tire accident again, warning people to pay attention to the tire safety. Tire ismainly due to the high temperature of tire and brake, overload and over speed，therefore,reduce the tire and brake temperature become an urgent need for the majority of people.At present, there still exists a gap between the domestic technology and foreigncountries, after reference to the most information.The subject of the use of advanced technology of the existing aluminum alloywheels for reverse, design a three-dimensional model of air cooling type and then on thisbasis, using CATIA software to get the entity model. The wheel spokes is designed forfan blade type, namely all spoke into a blade shape, the wheel rotates, the air cooling fanunique characteristics and principle of air directly to sweep away the rim and brake, tire,rim and brake itself or other factors generated heat, reduce the temperature of the tire,wheel and brake at travel in a certain extent, to achieve the cooling effect.For the study of the air-cooled cooling-wheel, this topic mainly study the followingaspects:1、Understand the relevant laws and regulations of the aluminum alloy wheel, usingthe reverse engineering technology to reverse existing aluminum alloy wheels, andobtained the data points, and using3D software to establish a three-dimensional model;2、On reference to the relevant standard GB/T5334-2005,and based on thethree-dimensional model, compared the new wheel and the original wheel dynamicbending fatigue test comparison and element analysis;3、On reference to the relevant standard GB/T5334-2005,and based on thethree-dimensional model, compared the new wheel and the original wheel dynamic radialfatigue test comparison and element analysis;4、On reference to the relevant standard GB/T5334-2005,and based on thethree-dimensional model, compared the new wheel and the original wheel impact testmethod and element analysis;5、After the new air-cooled cooling wheel, meeting the three criteria basis,air-cooled cooling wheel simulated vehicle speed, according to its cooling effect of thefinite element analysis and comparison test. Through the analysis of the simulation test finite element contrast, coolingperformance of wheel strength reaches the original wheel requirements, to verify thefeasibility of the design concept and the research method of this topic, and providereferences for the design and subsequent.
