The invention provides a frame bench test device, a test method, a test device and a storage medium, and relates to the field of commercial vehicles. The device comprises a portal frame; a first end of the actuator is connected with a cross beam of the portal frame; the front axle tool assembly is connected with the second end of the actuator; and the rear axle tool assembly comprises a rear axle support and a simulation rear axle, and the simulation rear axle is movably arranged relative to the rear axle support. Through the specific structure of the vehicle frame bench test device, the inter-axle movement of the vehicle frame can be realized, and the consistency with the movement trend of an actual component mechanism is ensured. In addition, the collected stress result and the rack stress calibration result are directly used as damage calculation and equivalent data, and the reliability correlation precision of the rack test and the road test can be improved.

The invention relates to a steel frame-cold-formed thin-walled steel shear wall which comprises a steel frame, a cold-formed thin-walled steel keel is mounted in the steel frame, and keel node reinforcing devices are arranged at nodes of the cold-formed thin-walled steel keel. The steel frame-cold-formed thin-walled steel shear wall is formed by embedding the cold-formed thin-walled steel keel into the steel frame and belongs to a novel steel frame-shear wall structure, the overall rigidity of the cold-formed thin-walled steel wall body is improved through the keel node reinforcing device, the cold-formed thin-walled steel wall body and the keel node reinforcing device can work well in a cooperative mode, and the overall rigidity of the steel frame-cold-formed thin-walled steel shear wall is improved. The ductility, the ultimate deformation capacity and the energy dissipation capacity of the wall can be effectively improved, rigidity degradation can be delayed, and the bearing capacity ...
