Line simulation experiment platform for straddle type monorail working vehicle and test method of line simulation experiment platform

The invention provides a line simulation experiment platform for a straddle type monorail working vehicle and a test method of the line simulation experiment platform. The line simulation experiment platform for the straddle type monorail working vehicle comprises a platform steel framework, vehicle safety hooks, fixed rollers, movable rollers, transmission chains, driving hydraulic pumps and a hydraulic circuit system, wherein the vehicle safety hooks are fixedly connected with the platform steel framework, the fixed rollers and the movable rollers are symmetrically arranged on the top face of the steel platform framework in a spaced mode and connected with the driving hydraulic pumps through the transmission chains, and the driving hydraulic pumps are communicated with the hydraulic circuit system. The line simulation experiment platform for the straddle type monorail working vehicle can replace a straight test line of the straddle type monorail working vehicle and greatly reduce experiment cost; the walking conditions of road surfaces with rain or snow or frost, or dry road surfaces or other different road surfaces can be simulated by adjusting the friction force of the experiment platform, and powerful support can be provided for vehicle performance experiments.
