A TEST FACILITY FOR THE MEASUREMENT OF HEAVY VEHICLE SUSPENSION PARAMETERS

The new Highway Safety Research Institute Heavy Vehicle Suspension Testing Facility is a permanent facility for the measurement of compliance, kinematic, and coulomb friction properties of heavy vehicle suspension and steering systems in response to vertical, lateral, and brake forces, and roll and aligning moments. Single- and tandem-axle suspensions of all common on-highway track widths can be tested in their normal configuration or as mounted on an abbreviated frame section. The measurements are steady- or quasi-steady-state. The facility has three major mechanical systems: a static structure, a movable table, and four wheel pad assemblies. The test methodology is described, and qualitative findings to date are given. Appendices contain more detailed descriptions of certain machine elements and specific suspension data.
