Abstract


In this paper , as the research object , first introduced the numerical method of driving parametric design process , UG secondary development muffler UG secondary development of UG environment to play a key role in the control of vehicle noise muffler step modeling purposes UG software the muffler model database management system , and a customizable user interface the muffler model database management functions . Then application of the results of the secondary development of rapid modeling capabilities numerical analysis method of the Xinyuan XY200GY motorcycle muffler finite element analysis , calculation of the muffler performance muffler , and the validity of the calculation method is verified by experiments , Finally, in -depth understanding of the performance and mechanism of the muffler on the basis of the integrated use of the method and theory of the noise and vibration control , combined with modal analysis method , on the basis of ensuring the flow properties of the muffler to improve its performance muffler . This article will apply UG secondary development of parametric design and finite element analysis method to combine the full application of UG Parametric Design is fast and efficient and accurate parameterized design generated the muffler model is applied to three-dimensional computer numerical analysis , muffler acoustic unified performance analysis method from computer-aided design to computer numerical analysis .
