Almost-balanced structural dynamics [PDF]

38th Structures, Structural Dynamics, and Materials Conference, 1997
Abstract Analytical models and experimentally derived models are often represented in the modal co-ordinates. The modal models include natural modes and their displacements. The scaling of the modes is arbitrary, and thus the scaling factor can be freely chosen.

Dynamic balance concept and the maintenance of the dynamic balance in humanoid robotics

2008 6th International Symposium on Intelligent Systems and Informatics, 2008
One of basic characteristics of regular bipedal walk of humanoid robots is the maintenance of their dynamic balance during the walk, whereby a decisive role is played by the unpowered degrees of freedom arising at the foot-ground contact. Hence, the role of Zero-Moment Point (ZMP) as an indicator of dynamic balance is indispensable.

Measures of dynamic balance during level walking in healthy adult subjects: Relationship with age, anthropometry and spatio-temporal gait parameters

Proceedings of the Institution of mechanical engineers. Part H, journal of engineering in medicine, 2019
The maintenance of balance in dynamic conditions (e.g. during walking) is a necessary requirement that motor control must reach to avoid falls. However, this is a challenging situation, since to ensure the forward progression of the body, the center of ...

The effect of firefighter personal protective equipment on static and dynamic balance

Ergonomics, 2019
Firefighters work in unpredictable conditions, necessitating the use of personal protective equipment (PPE). However, the additional weight from the PPE and self-contained breathing apparatus (SCBA) alters their centre of mass (COM), restricts movement ...

On the dynamics of the fluid balancer

Journal of Fluids and Structures, 2014
Abstract This paper is concerned with the dynamics of a so-called fluid balancer; a hula hoop ring-like structure containing a small amount of liquid which, during rotation, is spun out to form a thin liquid layer on the outermost inner surface of the ring. The liquid is able to counteract unbalanced mass in an elastically mounted rotor.

Anthropometric Changes During Pregnancy Provide Little Explanation of Dynamic Balance Changes.

Journal of Applied Biomechanics, 2019
The authors investigated the relationship between anthropometric changes and dynamic balance changes during pregnancy. A total of 15 participants were recruited for testing, using a convenience sample, from 12 weeks of gestation until childbirth.

Specificity of Learning and Dynamic Balance

Research Quarterly for Exercise and Sport, 1996
Contrary to a strict specificity of learning position, Robertson, Collins, Elliott, and Starkes (1994) have reported that the balance beam performance of expert gymnasts is less affected by the withdrawal of vision than is the performance of novice gymnasts.
