Outline |
|
One degree of freedom vibration is described in basic vibration problems. This course describes free vibration, natural frequencies, forced vibration and its resonance in the one degree of freedom model composed of mass, spring and damper. The objective is to study basic principles and laws in vibration engineering.
In this class, it acquires knowledge, technology and ability about diploma policy 2 and 3 and 4.
|
| ２． |
Objectives |
|
Vibration engineering in machine design is important to fatigue fracture under cyclic load. Also, it is important for the refinement of design in order to solve problems of automobile riding comfort and so on. This course describes free vibration, natural frequencies, forced vibration and resonance using a simple model composed of mass, spring and damper. The objective is to study basic principles and laws in vibration engineering.
