A geometric approach to the static balancing of mechanisms constructed using spherical kinematic chain units [PDF]

Mechanism and Machine Theory, 2019
A geometric method to the static balancing of mechanisms constructed using spherical chain units is presented. A (serial) spherical kinematic chain unit is composed of n moving links, whose masses are considered, connected by revolute (R) joints the axes

Succinct Representation of Balanced Parentheses and Static Trees

SIAM Journal on Computing, 2001
Summary: We consider the implementation of abstract data types for the static objects: binary tree, rooted ordered tree, and a balanced sequence of parentheses. Our representations use an amount of space within a lower order term of the information theoretic minimum and support, in constant time, a richer set of navigational operations than has ...

Statically balanced direct drive manipulator

Robotica, 1989
SUMMARYA practical architecture, using a four-bar-linkage, is considered for the University of Minnesota direct drive rotot. This statically-balanced direct drive robot has been constructed for stability analysis of the robot in constrained maneuvers.2–6As a result of the elimination of the gravity forces (without any counter weights), smaller ...

Static balance and developmental coordination disorder

Human Movement Science, 2003
The development of static balance is a basic characteristic of normal motor development. Most of the developmental motor tests include a measure of static balance. Children with a developmental coordination disorder (DCD) often fail this item. Twenty-four children at risk for DCD with balance problems (DCD-BP) and 24 matched control children in the age

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.

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
