Force identification of an outboard engine by experimental means of linear structural modeling and equivalent force transformation

Force identification of an outboard engine by experimental means of linear structural modeling and equivalent force transformation

This paper presents a study of experimental identification of vibration force generated in a single cylinder outboard engine under a steady-state operation by means of linear structural modeling and equivalent force transformation. The identification is to determine a set of equivalent force vectors...

description This paper presents a study of experimental identification of vibration force generated in a single cylinder outboard engine under a steady-state operation by means of linear structural modeling and equivalent force transformation. The identification is to determine a set of equivalent force vectors that can express actual vibration force generated by firing and inertia force due to dynamic motion of moving components in the engine. The vibration force generated in engines under steady-state operation will be independent of the boundary conditions excluding load condition. Therefore, once such vibration force can be modeled with practical accuracy, the result can be used as a database for CAE simulations of trouble shooting and design improvement analysis for noise and vibration, etc.
