Research On The Development Of Rapid Design System Of Semi-Trailer And Its Optimization

With the development of CAD technology, the use of computers in a virtual state ofsemi-trailer in modeling and finite element method has become the manufacturers'preferredmethod for new vehicle design and models for improvement. Now production level ofsemi-trailer has been greatly improved than before.The rapid design system of semi-trailer tanker is developed for the demand of market, for woking out thecontradictions between the individual needs and design speed. The rapid design system makes the semi-trailertanker in module division, uses UG / Open as a development tool, parametric modeling. Integrate Patran in therapid design system as the quality feasibility test subsystem, which cold make static calculation and modalanalysis on the semi-trailer tanker.The rapid design system of semi-trailer tanker establishes database by Microsoft Office Access, includingmodels database, components database, material and properties database, where save the models, componentsand material of the semi-trailer tanker. The database is open, the newly designed parts and models can beadded to the database to make it more perfect.
