This work solves the challenge of separating the eccentricity error of a workpiece installation from the first harmonic of radial runout error of the spindle, which has a crucial impact on improving the machining quality of the workpiece. Firstly, a...
To investigate the influence of radial installation and radial eccentricity errors on the load-sharing performance of a four-point drive system, a dynamic model is developed using the lumped mass method and Timoshenko beam element theory. The model c...
In this article, a method of error source analysis and detection to improve the angle measurement accuracy of rotary encoders in precision measuring instruments is proposed. The angle measurement error caused by the installation eccentricity of the g...
In this paper, a type of co-excitation axial reluctance resolver (CARR) in different winding modes is taken as the simulation model. Detailed explanations have been provided on its stator, rotor, and windings. Simultaneously, an introduction was made...
Laser fusion research requires a large number of high-precision large-diameter aspherical components. To improve the grinding efficiency in the component production process, the manual operation time during the grinding process needs to be reduced. T...
The rotary seal is a key component of the aero engine. Under actual working conditions, most rotary seals always operate in an eccentric state (caused by installation errors), and when a large eccentricity occurs, it may lead to a large amount of gas...
Installation eccentricity of an in-pipe ring array changes the water-layer propagation path and degrades time-of-flight (TOF) extraction in small-diameter thin-walled tubes. This study proposes an array-level physics-informed neural network (PINN) th...
During the construction process of prefabricated helical anchor foundations, eccentricity and inclined installation of anchor rods may alter the stress distribution and interfacial load-transfer mechanism within the UHPC grouting connection zone, res...
Accurate current sensing in rectangular conductors is challenged by mechanical deformations, including eccentricity (X/Y-axis shifts) and inclination (Z-axis tilt), which distort magnetic field distributions and induce measurement errors. To address...
The magnetohydrodynamic (MHD) micro-angular vibration sensor is a significant component of the MHD Inertial Reference Unit (MIRU) and measures micro-amplitude and wide frequency angular vibration. The MHD micro-angular vibration sensor must be calibr...
Due to the existence of machining and installation errors, axis parallelism error of gear pairs occurs, which causes eccentric load and mesh in-out impact, thus weakening loaded transmission character. To solve this problem, the axis parallelism erro...
With the depletion of oil and gas resources and increasing exploration difficulty, dynamic well inclination measurement has become increasingly important. Near-bit dynamic well inclination measurement can improve borehole trajectory calculation accur...

Laser trackers are instruments used to measure the three-dimensional coordinates of objects with high precision. It is necessary to study calibration methods to identify geometric errors of laser trackers so as to compensate for errors and improve me...
Measuring the radial error motion of a spindle during the cutting process is important for monitoring the machining quality of the workpiece and spindle running condition. The problem of long separation time encountered in the application of traditio...
Transmission error (TE) and backlash are important parameters used to evaluate the transmission accuracy of cycloid-pin drives. Existing calculation methods are mostly based on two-dimensional tooth profile models, and these methods ignore the influe...
The accuracy of the circular grating is the key point for control precision of the single gimbal control moment gyroscope servo system used in civilian micro-agile satellites. Instead of using the multi reading heads to eliminate eccentricity errors,...
A visible light camera payload with star-sensitive functionality was installed to measure the distance between a non-cooperative target satellite and a high-orbit satellite. The rotation matrix was used to calculate the pointing vector from the cente...
During a manufacturing process, it is essential to quickly identify whether a tool needs to be replaced or adjusted, to ensure that production quality is not compromised. Therefore, the re-inspection of the product or first article inspection is an i...
Mobile platforms for installing prefabricated pipe and duct modules inside buildings must transport long payloads and lift them to elevated work positions. Changes in payload arrangement and height alter stability margins and load-transfer responses....
