Dynamic Load Test and Contact Force Analysis of the AERORail Structure

The flexible structure of the new type aerial track studied in this paper is formed by strings and tracks, which have obvious dynamic characteristics under action vehicle moving loads also an important factor affecting its performance. uses full-scale model AERORail, based on modal test a specific span, combined with fundamental frequency analysis structure, carries out load to determine change law contact force acting rail load. time-domain improved algorithm method moments used identify analyze different spans speeds correlation between dispatched speeds. It proven that occurrence time are related passing vehicle. fluctuates speed, but increase fluctuation decreases obviously. relevant conclusions provide support for layout AERORail For innovative basis application novel structure.
