“…In other words, we observe how nanotori are controlled by a consistent gyroscopic effect [39]. Gyroscopic effects are widely used and have great prospects in micro-and nanodevices [26,[40][41][42][43][44][45][46].…”

Supramolecular interaction of carbon nanotori in a columnar phase is described using the methods of classical molecular dynamics. The collective behavior and dynamic properties of toroidal molecules arising under the action of the van der Waals forces are studied. The conditions under which columnar structures based on molecular tori become unstable and rearrange into another structure are investigated. The reasons for the appearance of two types of directed rotational motion from the chaotic motion of molecules are discussed.

“…Precession and nutation of the gyroscope will occur under the action of an external moment. The gyroscopic effect is found in various fields, such as mechanical engineering [19][20][21], hydropower engineering [22,23], aerospace engineering [24,25], wind energy engineering [26,27], vehicle engineering [28], astronomy [29], and so on.…”

Due to perturbation forces and control forces, trajectories of spacecraft around the Earth are usually non-Keplerian orbits, which may result in a gyroscopic effect. To meet the complex demands of space operations in the future, the trajectory prediction of spacecraft under the influence of the gyroscopic effect generated during non-Keplerian motion needs to be studied in depth. The paper investigated the trajectory of spacecraft under the gyroscopic effect generated during non-Keplerian motion. Firstly, according to the similarity between the spacecraft precession motion and the gyroscopic precession, as well as the definition of the “gyroscopic effect” of high-speed rotating bodies, the “gyroscopic effect” generated during the non-Keplerian motion of spacecraft around the earth was defined. Then, taking a continuous radial thrust orbit as an example, the dynamics equations of spacecraft under the influence of gyroscopic effect were deduced. Through theoretical analysis and numerical simulation, the trajectory of spacecraft under the influence of the gyroscopic effect generated during non-Keplerian motion was investigated. Finally, the paper simulated the examples and tested the performance of the proposed method. Simulation results show that a large gyroscopic moment may be generated in some non-Keplerian motion of the spacecraft. The greater the rotational angular velocity of the orbital plane, the greater the gyroscopic moment. Due to the gyroscopic effect, there is a significant deviation in the orbit and the orbital elements compared to those without considering the gyroscopic effect, which indicates that the influence of the gyroscopic effect generated during non-Keplerian motion on the orbit of the spacecraft cannot be ignored. It can be seen from the simulation results that the gyroscopic effect has a significant influence on the trajectory of spacecraft. In some special cases, the gyroscopic effect can be utilized reasonably to save fuel and realize low-energy orbit maneuver control technology in actual space missions; but the control should be considered for the spacecraft to bring it back to the desired orbit in most cases. It is necessary to study the trajectory of spacecraft under the influence of gyroscopic effect. The method and conclusions proposed can provide a theoretical reference for spacecraft trajectory prediction and future large-scale fast orbital maneuvers to meet the needs of complex space operations.

“…Dynamic events described in this article were addressed in the past and many outputs are published, like simulation model of the dynamic behavior of refrigerated products in a ship's refrigerated container by Bupič M. et al [12] or in applications of gyroscopic eff ect in transportation by Náhlík et al [13]. The studies of vehicle dynamics lead to the safety of transport as described in Vlkovsky et al articles [14], [27], [23] or in Skrucany et al [17], [25], [28].…”

To ensure safety during transport within the intermodal chain, it is important to identify possible dynamic events that could affect the cargo. In the case of bulk cargo in an ACTS (Abroll-Container-Transport-System) container, the dynamics of the cargo and the vehicle vary during normal events such as braking, steering, evasive maneuver and the like. In this research, we used MEMS (Micro-Electro-Mechanical Systems) sensors to identify the parameters of acceleration at various points of container and to evaluate its impact on the cargo and vehicle. During the research, we also found out how the load of individual axles of the vehicle changed after performing normal dynamic events. One of the objectives was also to find out how parameters such as braking distance, braking time and mean fully developed deceleration (MFDD) change in the case of and empty and loaded ACTS container, as well as correlation analysis of values gathered from sensors placed on different parts of the container. The acquired knowledge can be used in the distribution and securing the cargo.
