35、or Engineering Reference A MORE EFFECTIVE AND EFFICIENT METHOD FOR THE DESIGN OF TUBULAR PRODUCTS USED IN ENGINE AIIUFLUID SYSTEMS HAS BEEN DEVELOPED. This method involves the simple use of a line drawing (center line) and XYZ coordinate table. An example of this method is shown in Figure 10. All ra

36、dii are specified to the center line of the pipe This document is restricted and may not be sent outside Navistar International Corporation or reproduced without permission from Corporate Technical Standards.

APRIL 1999 Page 4 of 12 COPYRIGHT International Truck and Engine Corporation (formerly NAVISTAR)Licensed by Information Handling ServicesNUMBER: TITLE: RE VISION: TMS-1059 Aluminum Tubing For Engine Air/Fluid Systems C and all dimensions are given from the centerline and intersectin

38、g points. Provision of coordinates is via the XYZ-Tubing program available within the UNIGRAPHIC GRIP Program system. Design Procedure for Engineering Reference (Continued) The use of this design method facilitates transfer of data from the engineering drawing to manufacturing operations because the

39、 data can be transferred directly into CNC controlled tube benders and/or coordinate measuring systems to permit manufacturinghnspection without the need for intermediate manufacturing drawings and/or checkinghesting templates fixtures. The elimination of these steps improves efficiency/economy of o

40、perations. The use of the XYZ coordinate system is essential to establish the appropriate interface between the UNIGRAPHICS design system and the “Bar and Tube Design Expert System“ which is planned to be installed on the Engineering “Network“. The use of the expert system will enable the designer t

41、o optimize his design with respect to product cost. In order to obtain maximum life for pipekubing systems and to minimize costs, procedures described herein should be followed. This is particularly important with regard to bend radii and bend locations relative to each other. “Press“ (compression)

42、bends generally have higher production rates and hence lower costs than “Mandrel“ bends and should be used whenever space permits their larger radii and lesser degree of bend. The supplier should be consulted for the preferred bend radius and availability of tooling before release of the drawing. Av

43、oid bends which are too close together and the use of “bends-within-bends.“ They are difficult to fabricate, require non-standard tooling, and add significantly to the cost of the product. In many cases, rotating the bends (as shown in Fig. 6) will achieve the same result while permitting the use of

44、 standard tooling and reducing the costs. Use Chart #1, if necessary, to maintain adequate distance between bends as shown in Fig. 8. All radii on each pipe/tube should be the same in order to minimize tool changes and Set-up time. The exception to this rule is the special case where bends smaller t

45、han those shown in Chart #1 are necessary at one or two points and space permits the use of larger bend radii (as shown in Chart #1) at other points. The tubing fabricator/supplier should be consulted for guidance in these cases. Pipes used in charge air coolers and air cleaner systems are often con

46、nected to elastomeric hose(s) or use elastomeric connectors to reduce vibration. Beading at the end of the tube is used to provide adequate sealing and pull-off resistance. To reduce the transmission of vibrations and stresses between the engine and the radiator/CAC, a minimum spacing or gap of 2.0

47、inches should be maintained between the pipe and turbo charger and also between the pipe and the CAChadiator. The length of the pipe and the lengths of the lose connectors must be carefully considered in order to maintain the gap spacing. Figures 5 and 7 indicate bead configurations used in current

48、design. Consideration for ease of assembly, anticipated peak pressures, and analysis of stack-up tolerances may aid in selection of the proper bead configuration.
