Dynamic Response Tests of an Air Cushion Suspension System for the Linear Induction Motor (LIM) of the Tracked Air Cushion Research Vehicle (TACRV).

摘要

The report presents the results of a test program to determine the dynamic response characteristics of an air cushion suspension system. The air cushion and secondary suspension are designed for the support and guidance of the linear induction motor (LIM) on the 300mph Tracked Air Cushion Research Vehicle (TACRV). The tests simulate the motion of the suspension system on the TACRV moving over a guideway with sinusoidal surface irregularities. The test variables included oscillatory excitation amplitude,air supply system admittance,air cushion skirt configuration and reaction rail flexibility. Test results are compared to theoretical response predictions for both the LIM support and guidance systems. (Author)
