5、ate for SAE J826 H-point Machine RATIONALE The SAE HADD Committee recently developed computer-aided design (CAD) data representing the SAE J826 2-D H-point machine (HPD) template. Prior to this activity, CAD versions of the HPD were created by end users based on scans of the official physical plasti
6、c template for SAE 2-D J826. This standard provides traceable documentation for the SAE HPD CAD files that can be used as a design template or can verify the shape/ size compliance of existing templates. This project coincides with the SAE HADD Committees creation of CAD surface data for the SAE J82
7、6 3-D H-point machine (HPM-1) cushion and back pan outer shells published in J826/1_2011. Previous documentation describing the production SAE J826 HPM was contained in a series of 2-D dimensional layout drawings from 1974, the final assembly fixturing jig, and in other minor build and SAE J826 revi
8、sions made over the years. Key changes to the template since the earlier plastic template versions include: x Values for the Thigh Length and Lower Leg segment lengths have been updated to reflect values set for the physical HPM-I in J826_2015. x New segments for the Thigh and Lower Leg were created

The elements of the HPD include the curve shapes, datum points and lines, and calibration references. The intended purpose for this informa
13、tion is to provide a master CAD reference for design and benchmarking. The content and format of the data files that are available are also described. 2.

22、he top surface of the metal plate that is mounted on the inner fiberglass surface between the legs of the HPM. This is the only inner HPM surface that is part of the 2D CAD model. 4.2 CAD Assembly and posturing The Torso segment, the shoe segment, the selected Thigh segment, and the selected Lower L
23、eg segment are required to assemble a complete 2D template. These segments are connected to one another at common points identified on each segment. x The Torso is connected to the Thigh segment at the H-point. x The Thigh is connected to the Lower Leg segment at the Knee Joint. x The Lower Leg segm
24、ent is connected to the shoe segment at the Ankle Joint. (see Figure 1.) Four parameters are needed to posture the HPD in a vehicle package: a known torso angle, H-point location, Shoe Plane Angle, and Heel point. These parameters can be determined from a physical installation of the 3-D HPM in a de
25、signated seat position, or from manufacturer specifications (see Figure 2). SAE INTERNATIONAL J826/2 OCT2016 Page 5 of 9 Figure 1 - Side view of the assembled 95th2-D HPD template reference posture Position the H-point of the CAD model at an H-point location in the H-point travel path of the seat. (
26、Typically, this is the manufacturer SgRP location.) The Torso and Thigh (Cushion) Lines are positioned in the Y-centerplane of the designated seating position. The Thigh and Torso segments of the HPD pivot about the H-point. To orient the Torso segment, set the Torso Line to the design Torso Angle,
27、A40. To orient the Thigh segment, set the Thigh (Cushion) Line to the Thigh Angle, A57 (or Cushion Angle, A27).
