Highlighting when animals expend excessive energy for travel using dynamic body acceleration [PDF]

iScience, 2022
Summary: Travel represents a major cost for many animals so there should be selection pressure for it to be efficient – at minimum cost. However, animals sometimes exceed minimum travel costs for reasons that must be correspondingly important.

Excessive Acceleration Criterion: Application to Naval Ships [PDF]

Journal of Marine Science and Engineering, 2019
In this paper, the application of the excessive acceleration (EA) criterion, one of five intact stability failure modes, within the second generation intact stability criteria (SGISC) framework, is shown for a set of naval vessels. First and second level vulnerability assessment of the criterion is applied to parent hulls D1 and D5 of D-Systematic ...

Effective acceleration design for solving excessive vibration in the cockpit

Vibroengineering PROCEDIA, 2023
To address the issue of vibration discomfort caused by excessive vibration in the cockpit, a method that allocates vibration reduction index (VRI) to different vibration transfer paths is proposed. By combining the identified vibration contribution of vibration sources using the transfer path analysis (TPA) method with the evaluated relative difficulty

Vulnerability Assessment for Excessive Acceleration Failure Mode of an Indonesian Ro-Ro Ferry by Model Experiment

International Journal of Technology
The Indonesian ro-ro ferries have a large breadth-to-draught ratio and metacentric height. The passenger and crew accommodations are located at a significantly higher position from the roll axis because the main deck is used as a vehicle deck.

Vulnerability of Ship with a Large Breadth to Draught Ratio Against Excessive Acceleration Criteria

IOP Conference Series: Earth and Environmental Science, 2023
Abstract A ship having a large breadth and small draught may have a large metacentric height. Therefore, the ship could be vulnerable to the excessive acceleration criteria. In order to investigate the vulnerability, an Indonesian ro-ro ferry with breadth to draught ratio of 5.31 was used to apply the criteria.
