A digital computer program is presented capable of determining the in-and/or out-of-plane vibration frequencies of a single engine piping system. The analysis is made utilizing the method of transfer matrices, a discussion of which is included. The program accepts branched systems with or without intermediate supports. The effects of both shear deflection and rotational inertia are considered although either or both may be neglected at the user's discretion. Distributed mass is generally treated as such, although provision is made for alternate treatment by lumping mass. Several typical piping systems are analyzed using these various program options, and the results obtained are compared.
