Abstract:
Although spinal manipulation is widely used in the management of neck and pain, its exact mechanisms and biomechancial effects are not clear. A porcine model was used to study the relative movements of intervertebral joints under spinal rotation maneuvers with different input angular displacements and thrust velocities. Ten porcine spines (C2/4) were fixed and mounted in a material testing machine. Rotational maneuvers with different input angular displacements (0.8, 1.5, 2 and 3°) and thrust velocities (0.1 – 200°/s) were applied to C2 with C4 fixed. Angular displacement induced at the adjace

Linear and angular displacement is an important criteria for incompressible materials. Natural rubber is a one of the incompressible material because it has a potential to make uniform displacement when apply the quantum of force.

Abstract:
In the dimensional synthesis of a standard planar triad, if the prescribed angular displacements of two of the three links are the same at all precision positions or the prescribed angular displacements of one link are zero at all precision positions, the standard triad displacement equation will not yield a practical solution: a triad having all links with finite lengths. The displacement equation may also fail to generate a practical solution triad in case that the freely chosen angular displacement of one link equals to zero, or equals to the prescribed angular displacement of another link

Changes in friction due to angular motions at rough planar contacts are investigated using a compliant contact model that isolates an angular degree-of-freedom.

We assume that the friction force is proportional to the real area of (elastic) contact.

Abstract:
Physical therapists evaluate patients’ movement patterns during functional tasks; yet, their ability to interpret these observations consistently and accurately is unclear. Physical therapists would benefit from a clinic-friendly method for accurately quantifying movement patterns during functional tasks. Inertial sensors, which are inexpensive, portable sensors capable of monitoring multiple body segments simultaneously, are a relatively new rehabilitation technology. We sought to validate an inertial sensor system by comparing lower limb and lumbar spine kinematic data collected simultaneous

SummaryObjectives: The purpose of the study was to evaluate kinematic patterns in clinically normal Labrador and Rottweiler dogs trotting on a treadmill at a constant velocity. Methods: Ten Labrador Retrievers aged from 2.2 to 5.1 years, and 10 Rottweilers aged from two to 5.9 years were used. A three-dimensional capture system was used to perform analysis of joint kinematics. Kinematic data were collected by use of a triple-camera system. The kinematic study was performed first on the right side of the dog, and then on the left side. Data were analysed by use of a motion-analysis program. Fle

Abstract: A potentiometer can be used to measure angular displacement by converting the rotational motion into a corresponding voltage change. This method involves using a rotary potentiometer, where the angle of rotation is directly proportional to the output voltage. The angular displacement is determined by the amount of rotation of the potentiometer’s shaft, which is then translated into a voltage reading.

Abstract:
Misalignment is a common fault occurring in the rotor system. However, the response characteristics have not been understood comprehensively, especially the relation between forces or torques and displacements, accelerations, or moments. First, misalignment modeling is investigated in this paper. Two coupled rotor system is modeled by six degrees of freedom. Misalignment effects are considered at coupling location using nodal force vectors and moment vectors. Second, Newmark- β method is used to solve the nonlinear equations. Acceleration, displacement, and force or moment response characteris

Abstract:
The angular sensor is frequently used to measure relative angle changes between two structural components, from the perspective of working principles, it can be divided into "angular displacement" and "linear displacement" angular sensor. In the application under water, the watertightness of traditional angular sensor can not meet the requirements, and the sensor is easy to corrode in the sea water, causing damage to the sensor. The outer shell of new underwater angular sensor is made of 304 stainless steel, by making use of the exclusion principle of magnet and the synchronous changes of magn

The bullet-rifle coupling model of sniper rifle has established to study the impact of bullet mass eccentricity on initial disturbance. This coupling model was established based on nonlinear finite element method and used to simulate the launch process of sniper rifle under the condition of gravity static equilibrium in the method of the mixing calculation which had advantages of both dynamic explicit algorithm and static implicit algorithm. The impact of different initial position of mass center on bullet swing angular displacement and centroid displacement was considered. Numerical calculati

Abstract:
For finding the influence of the original errors on the follower of the globoidal cam, vector analysis method is used. Seven original errors are defined by analyzing the machine tool and the mathematics models between the follower angular displacement errors and the original errors are established. When the original errors are designed as 0.01, the relationship curves between the largest follower angular displacement errors and the cam angles are got. The error influence coefficients between the largest follower angular displacement errors and the original errors are established on that basis.
