Abstract Dynamic response of a length-limited elastic cylindrical shell is researched to meet engineering requirements, on which non-axisymmetric loads include a moving concentrated load and an uniformly distributed load with synchronously increasing range of action. Dynamic differential equations with symmetrical forms are derived, and the two kinds of synchronous moving loads are expressed by the Dirac function and the Heaviside function. Based on the assumed displacement functions, the analytical dynamic solutions to the displacement and stress of the cylindrical shell are obtained by means of the Galerkin method and Laplace transformation. The algorithm is verified through the comparative analysis of the analytical solutions and the ANSYS numerical solutions for a specific example.
