The natural frequency analysis of complex powertrain models created in Modelica presents a number of problems.This paper presents the basic principles and some of the problems associated with carrying out this kind of analysis.As a result of this work, a new feature in the Powertrain Dynamics Library has been developed to automate these methods and provide the end-user with a simple set of functions to perform natural frequency analysis.Simple examples are used to illustrate the problems and solutions and a complex powertrain model is then analysed using the library.
