Abstract: An experimental programme in 2007 used three air-suspended Heavy Vehicles (HVs) travelling over typical urban roads to determine whether dynamic axle-to-chassis forces could be reduced by using larger-than-standard diameter longitudinal air lines. This paper presents methodology, interim analysis and partial results from that program. Alterations to dynamic measures derived from axle-to-chassis forces with standard-sized longitudinal air lines vs. larger longitudinal air lines fitted are presented and discussed.
Keywords: air lines; dynamic loadings; heavy vehicles; payload increase; air suspension systems; dynamic forces; vehicle suspensions.
