Report writing, approval, processing, etc., are not part of these times. 3.5 Test Required Information. The requesti

21、ng engineer is responsible for providing specifications appropriate to the particular vehicle line being tested (reference Vehicle Technical Specifications (VTS)/Subsystem Technical Specifications (SSTS) paragraph numbers). Testing worst case scenarios may uncover some potential problems. Discuss wi

22、th the requesting engineer if testing should include some worst case scenarios. Depending on which test is being performed and which level of parts or systems is being tested, consider if any of the following may apply tolerance stack-ups, build variations, misalignment, minimum/maximum fastener tor

23、que(s), lubrication, environmental extremes, location of customer representative load application, symmetry (Left Hand vs. Right Hand), color, mold or die source, etc. 3.5.1 Power Window Specifications. The following specifications or information are required to run this test. 3.5.1.1 Stall time (am

Prior experience in setting up and running similar tests and experience in the use of the referenced test equipment are critical to achieving the estimated times shown in “3.4 Test Time”. 4 Procedure 4.1 Preparat

27、ion. 4.1.1 Sample Inspection. The test and requesting engineers should inspect the test items to ensure all material listed in 3.3 is of correct design level and assembled properly. 4.1.2 Sample Preparation. This test is normally run on the test subject in an “as received“ condition. If it is reques

28、ted to be run in a specifically adjusted condition, follow the applicable procedure(s). If installing a spindle modified power regulator assembly in a door, a hole may need to be drilled to allow spindle egress through the door inner panel. 4.1.2.1 Measure and adjust gap, flushness and seal margin d

29、imensions, if necessary (refer to GMW15938) to ensure the test material meets design specifications (required only if testing a door mounted on a body). 4.1.3 Facilities and/or Equipment Preparation. Record any instrumentation calibration information on Data Sheet A1. 4.2 Conditions. 4.2.1 Environme

30、ntal Conditions. Unless otherwise specified in this documents text or by the requesting engineer, the typical environmental conditions for this test are the temperature, humidity and pressure at the major test facility (3.1). Unless otherwise noted, these conditions are typically 22 +3 C, relative h

31、umidity of 40 +20% and atmospheric pressure equivalent to the local barometric pressure (which is variable during any given day and from day to day). 4.2.2 Test Conditions.

34、011 General Motors Company All Rights Reserved June 2011 Page 4 of 18 4.3.1.3 Motor temperature affects performance test results. If the power windows have been running durability tests, allow the motors to cool approximately 20 minutes before running performance tests. 4.3.1.4 Perform any functiona

35、l/operational tests/evaluations as requested by responsible engineer. If the window system has not been previously cycled, cycle the window “full up” and “full down” a minimum of 5 times prior to the start of test to assure proper operation and seating of all system components. As applicable, note a

36、ny irregular sounds or erratic operation indicating a potential problem with design, manufacture, or assembly and verify observations with the requesting engineer. 4.3.2 Test Operation Instructions. Note: Based on the window system to be tested, go to 4.3.2.1 (power) or 4.3.2.2 (manual). 4.3.2.1 Pow

37、er Window System. 4.3.2.1.1 If using the power window performance console to perform this test, plug the window performance console into a 120 V AC wall outlet. Press the green power button on the front of the console and the power button on the printer. Turn on the DC power supply at the bottom of

38、the console. 4.3.2.1.2 When prompted, enter the appropriate password. See a Body Test Lab support technician for the current password. The “Window Performance Test System, Live Status Info“ screen will then be displayed. See Figure A2. 4.3.2.1.3 On the toolbar, left click on “Edit“. From the dropdow

39、n menu, left click on “Setup Specs“. This causes the “Edit Setup Specifications“ screen to be displayed. 4.3.2.1.4 Enter Motor Maximum Stall Time (see 3.5.1.1) in the appropriate location. This value is typically 0.75 s. Enter the Test Temperature in the appropriate location. Test Temperature is for

40、 informational purposes only and is printed on the window performance plots. 4.3.2.1.5 Supply voltage can be set in one of two ways. If a known supply voltage is desired, enter that number in the location “Power Supply Voltage“. Alternatively, if a known motor stall voltage is desired, enter it in t

41、he location “Motor Stall Voltage“. 4.3.2.1.6 Left click on “OK“ to exit the “Edit Setup Specifications“ screen. Any changes made are automatically saved. 4.3.2.1.7 Make the proper electrical connections between the performance console and the regulator motor. If setting the power supply to a specifi

42、c voltage, use an electrical connection with a known resistance; otherwise, a short, 12 gauge wire harness with the proper matching connectors to minimize voltage drop is suggested (reference 3.5.1.3). 4.3.2.1.8 Left click on the “Up“ or “Down“ button in the area titled “Window Motor Control“ on the

43、 “Window Performance Test System, Live Status Info“ screen (Figure A2). Note: If the window travels in the opposite direction than desired, switch the polarity in the area entitled “Polarity“ on the “Window Performance Test System“ screen to correct. 4.3.2.1.9 If a known “Power Supply Voltage” was e

44、ntered in 4.3.2.1.5, skip to 4.3.2.1.10. If a known “Motor Stall Voltage” was entered in 4.3.2.1.5, left click on “Test“ in the toolbar. From the dropdown menu, left click on “Stall Voltage Adjust“. The “Stall Voltage Adjust Test“ screen is displayed. Note the advisories on this screen and left clic

45、k on “Continue Test“ when ready. This test will automatically adjust the supply voltage from the performance console to give the desired stall voltage. 4.3.2.1.10 Install the wire for connecting the stall force gauge and plug it into the front of the window performance console. Using 3.5.1.4 for a l

46、ocation, install the stall force gauge on the window at the glass center of gravity and mark its location (gauge location should be consistent during multiple testing). Position the stall force gauge so no rotation of the glass or gauge occurs during step 4.3.2.1.11. Do this by adjusting the tilt fe

47、et on the gage to make the gage align with the glass. See Figure A3. 4.3.2.1.11 On the “Window Performance Test System“ screen, left click on the “Cal“ button in the section entitled “Cal Load Cell“. Left click on “Test“ in the main window toolbar. From the dropdown menu, left click on “Stall Force“

48、. The “Stall Force Test“ screen is displayed. Note the advisories on this screen and left click on “Continue Test“ when ready. This will cause the window to rise until the stall force gauge seats into the upper glass run channel at which time the stall force will be measured. The window will then re

49、turn to a partially open position. When the window stops, remove the stall force gauge. 4.3.2.1.12 An option is now given to plot the stall force data. If this plot is desired, left click on “Yes“, otherwise, left click on “No“. See Figure A4 for a sample plot.
