Abstract: We consider the dynamic response of a single degree of freedom system with preloaded, or “setup,” springs. This is a simple model for systems where preload is used to suppress vibrations. The ...

Abstract: A mathematical model is developed to describe the characteristic behavior of an impact print hammer of the stored energy type. The armature of the impact print hammer is represented by a rigid ...

Abstract: The stored energy type of impact printer is a commonly used computer output device. It can be operated at quite high frequencies due to the fact that it has a large initial activation force. ...
