Linear Induction Motor Research Vehicle Speed Upgrading Tests (190to 250 MPH).

摘要

The linear induction motor research vehicle (LIMRV) was subjected to a series of test runs at speeds of 190to 250mph on the Department of Transportation 6.2-mile-long,standard gauge railroad track at the Transportation Test Center,Pueblo,Colorado. High-speed dynamic performance data on the vehicle,trucks,suspension systems,and LIM guidance system were acquired by means of instrumentation that measured accelerations and displacements. For these tests the LIMRV was fitted with two jet engines that enabled it to accelerate to high speeds during the first 2.3miles of travel,leaving nearly 4miles of track for constant-speed data collection and braking. The LIMRV operated in a fully stable manner dynamically up to the maximum speed attained, 255.7mph. Sufficient data was collected so that a safe LIMRV operating profile could be constructed as a baseline for conducting LIM electrical performance tests with full confidence in the vehicle's dynamic stability up to its design speed of 250mph.
