On the Impedance of Statically-Balanced Mechanisms

Volume 6: 35th Mechanisms and Robotics Conference, Parts A and B, 2011
Statically-balanced technology is often used to compensate partial or full gravity force exerting on a mechanism in order to reduce the effort of driving the mechanism. Since such compensation is static, when a statically-balanced mechanism is used for dynamic applications, it will still have impedance (mechanical resistance to input motion) because ...

Static Balancing of Tensegrity Mechanisms

Volume 7: 29th Mechanisms and Robotics Conference, Parts A and B, 2005
The computation of the equilibrium configurations of tensegrity mechanisms is often a very tedious task even for relatively simple architectures. However, it has been observed that the complexity of this problem is significantly reduced when gravitational loads are compensated with the use of static balancing techniques.

Static phase improvements in the LNE watt balance

Review of Scientific Instruments, 2016
This paper describes the mechanical and electrical modifications carried out on the LNE watt balance to reduce the noise level associated with the static phase. The mechanical improvements concern the home-made balance beam using flexure hinges as pivots of the force comparator.

Spatial Static Gravity Balancing With Ideal Springs

Volume 2: 28th Biennial Mechanisms and Robotics Conference, Parts A and B, 2004
This paper discusses mechanisms that allow for perfect static balancing of rotations about a fixed spherical joint by means of ideal springs. Using a potential energy consideration, balancing conditions of a spatial three-spring balancer will be derived.

Static Balancing of Centrifugal Fan

IOSR Journal of Mechanical and Civil Engineering
Centrifugal fans are critical in cement manufacturing for airflow regulation and dust management but often suffer from vibration-related faults due to harsh operational conditions. Excessive vibration, commonly caused by rotor unbalance and misalignment, can lead to premature component failure.

Optimum static balancing of an industrial robot mechanism

Engineering Applications of Artificial Intelligence, 2008
Force balancing is a very important issue in mechanism design and has only recently been introduced to the designing step of robotic mechanisms. In creating the best robot design, the statical balancing plays a vital role because it reduces the required motor power. To get a simple and more-effective control system, elimination or significant reduction

Dynamic and Static Balancing Ability of Preschool Children

Journal of Motor Behavior, 1971
Performance differences in dynamic and static balance ability of 150 preschool Ss aged 3,4, and 5 yr. were studied. Ss performed 4 balance-beam tasks and 2 balance-board tasks. An Age by Sex (3 × 2) factorial, design employing both univariate and multivariate ANOVA techniques were the statistics used.

Assessment of static balance in children.

The Journal of sports medicine and physical fitness, 1992
The ability in maintaining body balance of 6-, 8-, and 10-year-old children performing three balance tests on a force platform was studied. Thirty adult subjects served as a reference group. The mean radius (MR) of the posturogram and the mean speed (MS) of the center of foot pressure (COP) were used as the measuring parameters.

Static balancer for the rectilinear motion

2013 13th International Conference on Control, Automation and Systems (ICCAS 2013), 2013
This paper presents static balancers for a rectilinear motion using springs. A slider-crank mechanism is adopted as a base mechanism and is considered as a two-link and two-dof (degree of freedom) manipulator with an external load at the end-effector. The design of a gravity compensator is considered as mapping unit spring balancers to the slider-crank
