View NX's passenger car-based prediction method

With the rapid development of automobile industry, cars and people's lives with increasingly tight. Car is no longer just a simple transport, people still need cars outstanding performance in the other. In addition to appearance, the people still on the car's power, handling and stability and the economy put forward higher requirements for cars towards energy saving, environmental protection, safety three directions. Which in these three directions, security concerns become more and more. Perspective view, especially after the car the car driving safety and convenience of operation of large, so the total body layout design process, after the vision is very concerned about the performance as an aspect of the designer. In general, performance testing perspective rear view mirrors are in the post-conceptual design phase of the body, so not only can directly see the rear view mirror is good or bad performance, while early in the design can be found in the body design and layout problems and make timely changes. This shows that development of detection module rear vision mirror of great practical significance. In view of the design situation at home and abroad to study and master the design and after the relevant theoretical perspective, this paper to UG / NX as a software platform, using the supplied UG / Open API, UG / KF, UI Component such secondary development, At the same time with KF language and C / C language, with SAE and GB methods completed passenger cars, the exterior mirrors and endoscopy in the horizontal direction and vertical direction of the mirror to the field of vision test.Research in this paper after the passenger rear view mirror vision test module is in the conceptual design phase of the body, the model of the rear-view mirror vision testing.The main horizontal direction into the left outside rear view mirror vision testing, vision left outside mirrors detect vertical and right outside mirrors detect horizontal field of vision and right outside rearview mirror vertical field of vision test, horizontal vision endoscopic detection and endoscopic detection of six major vertical field of vision. After completion of the mirror design vision detection module, the user simply enter H point and vehicle parameters, the system will automatically calculate and generate the eye point, and then enter the mirror parameters, select the type of measurement, the system will come after the rear-view mirror visual field, and with the regulatory requirements in the field of vision compared directly to see whether the rear-view mirror designed to meet the vision requirements. This study was done by UG / NX Second Development provides rear vision mirror on the passenger car performance testing, test results can be seen from this module is practical. If the secondary development of technology to other aspects of body design, I believe that the realization of collaborative design, body design to improve quality and shorten the development cycle and cost a great boost.Therefore, this body design for the development of other aspects of the application module has a guiding role.
