In this paper the reverse engineering and software CATIA was used to create 3D model and virtual prototype of the car sunroof motion mechanism. Then the model was imported into Software ADAMS to create the virtual kinematics model. After that parameterized the model and an optimization design was carried out with sunroof motion mechanism in software ADAMS. Finally a transient dynamical FEA simulation...
In this paper the key technique in independent product development of car sunroof was researched. Firstly the reversal engineering and software CATIA were applied to create the 3D model and the virtual prototype. Then the 3D model was imported into ADAMS to create the dynamical simulation model. Finally the model was parameterized and the optimization design was carried out. The research work in this...
This paper presents firstly the structure and working principle of car sunroof. Then the reverse engineering and software CATIA were used to build the 3D model of motion mechanism of a car sunroof. Finally the 3D model was imported into software ADAMS to build the virtual Prototype. By applying with the software ADAMS the kinematic and dynamic character of sunroof motion mechanism components during...
The simulation method to design car interior trims based on NVH performance is introduced in this paper. An SEA (statistical energy analysis) model with all the parameters was built based on a domestic car. The inputs of interior noise were got by the combination method of roads testing and other simulations. The sound pressure levels in the engine bay and at driver??s ear in some running conditions...
In this paper the reverse engineering and Software Catia were applied to create the 3D digital model. Then the model was imported into ADAMS to build the virtual prototype. After that the key components which affect the movement characteristics of the sunroof were abstracted out to build the kinematic model. Then the virtual assembling, kinematics simulation and analysis were done with ADAMS software...
By using the technology of hydroforming and manufacture of the rear housing not only can saving material and energy resources, and also can bring about lightweight and improve the quality of products. For this reason had make succeed in developing new technology which by using seamless steel tube as blank and adopting hydroforming bulge be produce Auto drving axle housing. In order to perfect this...
In order to extend appled scope of new technology of the forward extrusion and cross rolling, was researched its forming princible.Then the distribution of stress-strain relations in the formed state and the characters of metal deformation and flow are analyzed in the tube billet during the process of the forward extrusion and cross rolling. The calculating method of the deformative force is also...
