Development And Application Of Inner Packaging Tooling Of Auto-Body Based On Catia V5

Auto-body packaging is a very important scheme design task during the automobile conceptual design phase. There are so many feature parameters and control hard points to be determined in the process of auto-body packaging; while spatial relations and constraint conditions are complex, implementation methods and evaluation indices are fuzzy. It results in the design scheme being multi resolution, experiential and compromising. It is very necessary to finish auto-body packaging work with advanced CAD/CAM techniques. For my company, there are many design experience about inner packaging, According to the broad application of CATIA in automobile industry, we decide to develop auto-body packaging system based on CATIA.For the autobody package design, you must make sure the driver room need to have enough position for dirver operating and passenger comfortable, so you need to use 2d human physical template to analysis the position.It is include: torso , seat back angle bar, thigh, lower leg, foot etc. the position of 2d human physical template will be decide by H point and hell point. It is 1:1 scale for using.The Eyellipse contours were developed by the statistical analysis of photogrammetric data of driver eye locations and represent a population mix, primarily of United States licensed drivers, with a male-to–female ratio of one-to-one. This recommended practice is based on an original study, involving drivers with a straight-ahead viewing task without head turning. The eyellipse centroid is located to the vehicle's three-dimensional reference system for three different male/female mixes (50/50, 75/25, 90/10 to 95/5) in the driver population. 95th and 99th percentile eyellipses are defined.A vehicle for the purpose of describing spatial requirements. Driver lateral head position includes head movement looking to the left and right while driving. Elliptical (head position contour) models in both two and three dimensions are used to represent 95th and 99th percentiles of driver and passenger head locations. 95th and 99th percentile head position are defined for no seat track travel (fixed seat) and for each of two different ranges of fore/aft seat track travel. Position can be constructed in three dimensions.A statistical representation of the driver's stomach location in a heavy-duty truck or bus with horizontally adjustable seats. An arc with a radius of 157.46 mm which defines the driver's stomach range. A series of two-dimensional side view lines which define the stomach contour x and z locations, and are defined to accommodate truck driver populations with male-to-female ratios of 50:50, 75:25, and 90:10 to 95:5.Shin-Knee Position is two-dimensional, 95th percentile truck driver, side view, seated shin-knee contours for the accelerator operating leg for horizontally adjustable seats. A statistical representation of the drivers' shin-knee location in a heavy-duty truck or bus with horizontally adjustable seats. An arc with a radius of -113.25 mm which defines the drivers shin-knee range (accelerator) with male-to-female ratios of 50:50, 75:25, and 90:10 to 95:5.The wiper system consists of all the apparatus for cleaning the exterior surface of windshield glazing, together with the necessary devices and controls to start and stop operation. The wiper system consists of all the apparatus for cleaning the exterior surface of windshield glazing, together with the necessary devices and controls to start and stop operation. The vision areas are described by three specific areas on the exterior windshield glazing surface, they are areas A, B, and C. The areas used in determining the percentage of wiped area are those areas on the exterior glazing surface which are not within 25 mm (1 in) of the edge of the daylight opening (pillars, division bar, header, etc.). The percentage is the ratio of the wiped area within the defined area to the defined area.Inner auto-body packaging work is a process about how to correspond the conflict of indexes. At the same time, the whole process need repeat correspond. A lot of experience and rules can guidance designer of auto-body. The paper steeply layout inner auto-body by concretely data. The writers conclude the method of SAE and give a reference of the whole inner auto-body packaging. The auto-body packaging system developed based on CATIA includes interrelated tools and rules of law, so it can enhance the design efficiency. All in all, this system can make full use of the advance strongpoint of CAD to enhance the efficiency of auto-body layout work. Please experts criticize and point out mistakes for ability of the writer.
