During the reliability performance test, the axial thrust balancing device of GFQ150-700 was overloaded and damaged due to an unsuitable designed value of axial thrust. The designed hydraulic axial thrust with the actual value is compared in this article, and the reason for axial thrust deviation is discussed. Related articles: Heart axis calculation, left-axis deviation, extreme axis deviation. In adults, the normal QRS axis is considered to be within −30° and 90°, right-axis deviation is considered from 90° to 180º 1.. Moderate right-axis deviation is from 90° to 120°, and marked right-axis deviation, which is often associated with left posterior fascicular block, . Axial dispersion and residence time distribution (RTD) have significant process implications in the design of continuous processes. Low dispersion is better for minimizing time for complete reaction and minimizing deviation boundaries. High dispersion is better for.the axial direction (A) the horizontal direction (H), and the vertical direction (V). Horizontal measurements typically show the most vibration due to the machine being more flexible in the horizontal plane. Also, imbalance is one of the most common machinery problems and imbalance produces a radial vibration, that is, part vertical and

the prediction of the deviation angle δ is taken. The deviation angle is the difference between outflow angle and the blade metal angle at the trailing edge. It can be estimated with the well-known Carter’s deviation rule (Carter, 1950). The following is a modified version including a MVDR correction and two additional calibration .

Axial length, a key measurement in myopia management, is not accessible in many settings. We aimed to develop and assess machine learning models to estimate the axial length of young myopic eyes. The main contributions of the current work are (1) a FEM is proposed by taking into account the actual well trajectory and by studying the contact force distribution; (2) the overall angle change rate has a significant influence on the axial load transfer; (3) the axial load transfer is sensitive to the buckling configurations of the drill-strings.
Radial runout is the deviation perpendicular to the shaft’s axis, while axial runout is the deviation along the shaft’s axis. Excessive shaft runout can cause vibration, premature wear, and reduced performance in rotating machinery. . Variations in material properties or density can lead to uneven weight distribution, causing runout.The Mohr-Coulomb failure criterion states that the shear strength of soil at failure (τ) is equal to:. τ = c + σ ∙ tanφ (6) Where: c is the soil’s cohesion. σ is the normal stress. φ is the angle of internal friction Hence, when more than one tests are conducted on the same material, utilizing different cell pressures, the various critical Mohr’s circles that are formed at failure . The early warning system for axial power deviation ΔΙ calculates the maximum axial power deviation ΔImax, then ΔImax would be used to calculate the maximum zone that the operational state point can reach, and it will also be used to determine whether the operational state point can return to the predetermined normal operational zone by R .
Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. Due to the fact that stress is applied along the longitudinal axis, the Unconfined Compression Test is also known as Uniaxial Compression Test. UCS is a parameter widely used in geotechnical design, but . In this work, a mathematical model for load distribution of planetary roller screw mechanism with pitch deviation is proposed. The load distribution coefficient on the screw–roller and nut–roller sides is determined based on the relationship between axial contact stiffness, axial contact deformation and axial load. The presented model considers the variations of the axial .

Tension test, alternatively referred to as tensile testing or uniaxial tension test, is one of the most commonly used tests to determine important material parameters such as Young’s modulus, yield strength, ultimate strength, elongation at break, Poisson’s ratio, and Lankford coefficients (R-values). In the topic of “stress distribution in the tensile test specimen” only a few experimental studies have been published [3, 7–9]. The effect of wedge and screw grips on the stress distribution in a tensile test piece is clearly demonstrated in Gray and McCombe earlier work. They used round specimens and strain gauges mounted onto the test . Parametric blade profiling is the key basis of influence analysis of geometric parameters [21], [22], [23].In this paper, twelve parameters are selected as the basic geometric parameters for the 2D blade profiling, including axial/tangential chord length b x / b t, pitch t, throat width a, leading/trailing-edge metal angles β 1 / β 2, short/long radius of leading-edge .
