With the continuous development of the knowledge of the automobile .The industry of the automobile has become more and more important in our industry. At meantime, the demand of the reliability and security of the motorcar is becoming higher. Now the motorcar is one of the most important parts in our house, and we pay more and more our attention to the reliability and security of the motorcar. And our government pays special attention to that too.The radiator is one of the most important parts of the engine cooling system, and plays an important role in it. The reliability and security of that effect the stability of the cooling system of the automobile motor. The cooling system of the motor consists of compressor, radiator, fan and so on. The most important of the cooling system is radiator. The most important techniques is the assembly line and effect the function a lot.Basing on the analysis above, the main of the paper is to study several assemble methods over the world. And make some improvement to increase the reliability, security and the resistance of fatigue and burst.Content: Based on the ANSYS software to analysis the resistance of fatigue and burst of the several assemble methods. Improve the design and the techniques to increase the reliability and security. And give some advice to the R&D of the radiator basing on the result of comparison. |
