Modeling specific processes in the formation and evolution of exoplanetary systems: Both studies of the exoplanet population and individual systems require modeling complex dynamical processes in a computationally efficient manner. A combination of analytical, semi-analytic, and The accurate measurement of roll angular rate for high spinning projectile has long been a challenging problem. Aiming to obtain the accurate roll angular rate of high spinning projectile, a novel extraction and filter algorithm, BSCZT-KF, is proposed in this paper. Firstly, a compound angular motion model of high spinning projectile is established.

Modeling of roll eccentricity based on modified FFT. With the ever-increasing demand for the quality of steel plate and strip products, roll eccentricity has become an important factor affecting the product quality. as the roll eccentricity signal is periodic, Fast Fourier Transform (FFT) is used for the modeling of roll eccentricity.

There are few detection methods which including rolling velocity. Roll eccentricity signal is difficult to directly measured, should fuse many kinds of detectable signal to be extracted through the data analysis which includes rolling force, roll gap, incoming thickness of rolled piece, exit thickness, tension, and so

Motion Control Coordinate System: In free space, an object is considered to have six degrees of freedom: three linear, along the x, y, and z-axes and three rotational around those (see Figure 1). All motions described here follow the right-hand coordinate system convention. The cross-product of +X and +Y axes (pointer and middle fingers) is the +Z axis (thumb).

the eccentricity conditions that are shown in Figure 3 (clearance is exaggerated). In the left-hand side of Figure 3, the sleeve is egg-shaped, as may happen with thin, large diameter sleeves. This produces the runout condition illustrated schematically on the left-hand side of Figure 1. On the right-hand side of Figure 3, the sleeve is offset

• Cut vs. cold form threads – Cut threads are easier to detect. Formed threads requires tighter insertion repeatability. Formed threads requires tighter insertion repeatability. • Base material – As this is an eddy current device, the base material must be electrically conductive.

The simplest type of mill vibration is found in all mills. It is a forced vibration due to roll eccentricity and so occurs at roll rotation frequencies. These frequencies are usually lower than any of the resonant frequencies of the mill stand. Therefore, gauge variation is a result of the stiffness response of the mill and the material on the

The paper reports on a study carried out to detect airgap eccentricity in large 3-phase induction motors. The philosophy of using a unified online monitoring strategy is presented and the reasons for selecting line current and frame vibration as the monitored parameters are discussed. A theoretical analysis is presented which predicts the presence of unique signature patterns in the current

Eccentricity in the finished product can mean wall thicknesses that don't meet specifications, causing problems during further processing downstream. MAC's Echomac UT test is applied after the extrusion process, while the tube is being drawn in a high-speed draw-production line, prior to further reduction.

Adopting the flexible Beta distribution as the underlying prior for eccentricity, we derive the marginalized transit probability as well as the a-priori joint probability distribution of eccentricity and argument of periastron, given that a planet is known to transit. These results allow to demonstrate that most planet occurrence rate

This simulation shows that with the observer, the effect of roll ecentricity is vastly reduced. In fact, for an eccentricity of 0.03, the effect on the output is 0.0024, which represents a 92% reduction, which is quite respectable considering the uncontrolled system performs a 66% reduction.

The essence of detecting eccentric signals lies in elimi-nating all kinds of noise contained in detected signals, sepa-rating the eccentric signals and taking the appropriate control strategy to reduce the effect of eccentricity on system [5]. Eccentricity signal in the coiling process behaves as a

Eccentricity is measured while the turbine is on slow roll (1 to 240 RPM below the speed at which the rotor becomes dynamic and rises in the bearing on the oil wedge) and requires special circuitry to detect the peak-to-peak motion of the shaft. This is accomplished using

Sep 20, 2018To calculate eccentricity of any vertex, we must know the distance between that vertex to all other vertices. Let's calculate the eccentricity for vertex A. So, the distances are: Distance between A and B – 1 Distance between A and C – 2 Distance between A and D – 1 Maximum of all these distances is the eccentricity of a vertex.
