Car Lights With The Development Of Automatic Modeling System Of The Light Pattern

With the development to the society and the improvement of people's stander of living, motor has enter many people's live. The development and advancement of motor's manufacturing technology promotes the updating of motor lamps technology whose main function is lighting and signal.Astigmatism veins is the main construction of motor lamps which used for beam adjust. There will be many astigmatism veins in the process of expiating new motor lamps using Reverse Engineering such as side astigmatism veins pole astigmatism veins triangle astigmatism veins, yuyan astigmatism veins pyramid astigmatism veins four-corner astigmatism veins six-corner fake astigmatism veins six-corner changed stigmatism veins and etc. The tradition way is to modeling every astigmatism veins manually. Because of the large kinds and amounts of astigmatism veins, and even some astigmatism veins must be numerical control programmed, the workload of modeling and program are too large and inefficient. Now we will introduce the auto-modeling system for astigmatism veins which under the environment of 3D software UG and its secondary exploit language Open GRIP.The auto-modeling system for astigmatism veins has two main tasks: secondary exploitation of basic functions secondary exploitation of applicational functions, secondary exploitation of basic functions includes the intersection of the multi-surfaces and a plane curves equality offset in surfaces and mesh generator entities array in the surfaces;secondary exploitation of applicational functions includes nine independent programs, including three auto-modeling programs for strip astigmatism veins three auto-modeling programs for four-corner astigmatism vein units and three auto-modeling programs for abnormal astigmatism vein units. We will introduce every programs in details including geometric construction modeling principle difficulties and the theoretic basis to solve the difficulties.Experiment shows that this system can greatly improve efficiency and quality of modeling and NC programming, reduce the limitation and mistaken of manual modeling, guarantee the veracity and accuracy of astigmatism veins' modeling, shorten the period of exploit new products.
