本文将电磁轨道发射装置的发射导轨及壁板简化为双层弹性地基梁。当电枢位于发射状态的某一位置时，在电枢接触力的作用下，建立了发射导轨及壁板的微分平衡方程。应用“影响函数”法，得到了双层梁位移和应力的解析解。通过算例，对发射导轨及壁板的变形和应力进行了分析，并将计算结果与 ANSYS 的分析结果进行了比较，相互佐证了解的可靠性。本文的研究结果可为电磁发射装置构件的强度、刚度设计提供依据。

Rails and panels of rail guns are simplified as double beams with bi-layer elastic foundations. Based on the situation of rails and panels under armatures' force during rail guns' launch, differential balance equations are established. Analytical solutions of displacement and stress of double beams are obtained by influence function method. Analytical solutions are verified by the com-parison of them with ANSYS results in a sample problem. The results have a reference to strength and stiffness design of rail gun components.
