SAE-RLDA Division Progress Meeting
SAE
Fatigue Design and Evaluation Committee Meeting Road
Load Data Division Unconfirmed Minutes Urbana, IL (October 11-12, 2000) Wednesday,
October 11 - Divisional Progress Meeting 1. Ray Thompson moderated the meeting. 2. Minutes from previous meeting were approved. 3. Mark Earley presented a review of the load measurement project on the ATV. Several test runs have been made, many over discrete objects for model correlation purposes. The data, along with photos and video of the test, have been placed on the web server. 4. Chakrapani Vallurupalli gave a technical presentation entitled “Functional Virtual Prototyping in Fatigue, Design and Evaluation Process.” 5. Ray Thompson lead a discussion about the web site www.fatigue.org. This is the site maintained by Christoph Leser. The committee member’s general consensus is that the above site complements the official SAE web site. The fatigue.org site is easier to get to (no password required) and easier to post information. Any updates or suggestions about the www.fatigue.org web site should be directed to christoph.leser(at)mts.com. Thursday, October 12 - Divisional Planning Meeting Ray Thompson chaired the meeting. Load data collected on the ATV was discussed. Mark Earley had collected additional data while operating over discrete objects and test tracks. The time history data has been placed on the web site in dac file format. There are 1886 data files using about 1 GB of disk space. Mark will do some data reduction (noise spike replacement, drift removal, etc.). He will also do the conversion of the wheel forces and moments from rotating coordinates to non-rotating coordinates. Run descriptions, channel descriptions, vehicle configuration details, photos and video have been posted on the web site. An Excel spread sheet documents the details. All the information can be found at www.fatigue.org/data. There was some discussion about the process of data reduction of the ATV data. Charlie Sieck and other individuals would like to do this procedure as well. This would include statistical analysis of multi-pass data. The raw data will be sent to them upon request to Mark Earley. It is desired that anyone participating in this exercise present their results at the next meeting. Ric Mousseau has plans to use some of the discrete bump data to correlate his dynamic model. Description of the test track profile and all discrete objects is included in the Excel spread sheet posted on the web. ASCII data file format was not discussed since the individuals working on this were not present. The meeting was adjourned. Minutes submitted by Ray Thompson |
