Identification of Time Variations of Moving Loads Applied to Plates Resting on Viscoelastic Foundation Using a Meshfree Method

Dynamic identification of the intensity moving loads applied to structures is an important task in aerospace, marine, and transportation industries. In present work, a general technique presented for time variations plate resting on viscoelastic foundation. The problem formulated as inverse problem, which utilizes dynamic responses. direct analyses required are performed by meshfree method based node technique. this technique, node, travels with force, utilized method. Since there no connectivity between nodes methods, can be implemented easily, while reducing computational labor. Another benefit that any simple or complicated trajectory load handled without additional concerns. Two numerical example problems solved effects several parameters, including measurement error, number sensors accuracy results investigated. Through examples, it shown identify efficiently accurately.
