Research Field
Evaluation on Performance of Spring Jack-up System
- Evaluation Item Function of Frequency Response, Natural Frequency, Spring Constant etc.
- Analysis Method Measuring vibration response at a vertical direction by impact excitation
- - “Natural frequency less than 3.75Hz, The ratio of damping 1.67%”
- Note Upon applying added mass, the natural frequency becomes lower.
