This study investigation is intended to research the dynamic response of horizontally curved bridges under heavy vehicle loads.Most Schmuck-Set of the main factors that affect the bridge dynamic response due to moving vehicles are considered.An improved 3D grid model, based on commercial software ANSYS Mechanical APDL, is developed for the analysis

Because of their wide detection range and rich functions, Wand Massagers autonomous underwater vehicles (AUVs) are widely used for observing the marine environment, for exploring natural resources, for security and defense purposes, and in many other fields of interest.Compared with a single AUV, a multi-AUV formation can better perform various tas
