In order to evaluate the mechanical condition and working performance of a rigid frame bridge after reconstruction extension, was analyzed by static load test. Static test is stress at each section main beam under action partial medium load. The results show that, load, check coefficient strain deflection measuring point box girder does not exceed standard limit value 1, relative residual or de...

This paper analyses the dynamic behavior of a rail vehicle using experimental and simulation analysis on multi-rigid–flex body model. The mathematical models are developed considering car body, bogie frame, wheel axle for vehicles rigid–flexible multi-rigid formulations, taking as rigid flexible flex–rigid analysis. A finite element model was in ANSYS, substructure modal were performed. is vali...
