Application Limitation of Boeing Bump to Evaluation Runway Roughness

Abstract:

Aiming at the situation that Boeing Bump will be the new method to evaluate airport pavement roughness in China, an analysis was made of the limitations to Boeing Bump's application. Boeing Bump was introduced in detail and the procedure of Boeing Bump Index (BBI) was developed meantime, based on ADAMS/Aircraft, the virtual prototype of typical aircraft was modeled, and with the field longitudinal profiles of 37 runways around the world, some problems of BBI and its criteria were explored. The results show that BBI has no ability to deal with multiple bumps on the runway, and is supposed to combine with some reaction evaluation index; some reasons, including the most unfavorable taxiing speed, single evaluation index and single evaluation aircraft, will make the criteria too loose, and the criteria of BBI should be corrected appropriately.
