Description
Zengchuang Zhao, Pingbo Wu, and Lihui Ren measured the surface unevenness of a working straddle monorail line, in a 2025 study. Trains on such lines ride astride a concrete beam, and bumps on its faces shake the vehicle. Simulations have long borrowed road or railway bump profiles for lack of true monorail data.
The team fitted onboard gear to a train in daily service and recorded unevenness along the whole line. They broke the data into spectra for the running face and the side guide faces. The spectra were compared with United States railway classes and international road classes, then fitted with formulas. Smooth and rough stretches got extra study. Based on the spread of values, the team sorted the measured spectra into two quality levels for use in design and modeling.
