Summary: This article introduces a FOG-based single-axis rotational inertial navigation system (RINS) instrument that automatically suppresses inertial sensor errors through rotation modulation technology. It also proposes a new dead reckoning (DR) algorithm based on the limited movement of the drill bit. However, the actual accuracy of the DR algorithm is affected by the installation errors between the instrument's axes and the pipeline. A new and practical calibration method is proposed to improve the accuracy of the DR algorithm. Simulations and semiphysics simulation experiments were conducted to verify the rationality and validity of the algorithm, showing that the proposed DR algorithm with installation errors corrected achieves a high positioning accuracy of 0.5% using FOGs with a drift of 0.015°/h. This study provides an innovative solution for high positioning precision in core drilling using a small-sized and low-cost RINS instrument.

Summary: This article proposed a rotary platform based on the stick-slip principle for high precision angle adjusting, adopting a dual-driven working mode to achieve large circular motion stroke and high loading capacity. By designing a flexible mechanism with two driving feet and actuating piezoelectrics alternatively, the back-off phenomenon was effectively suppressed and loading capacity was improved. Theoretical analysis and finite element simulation were conducted on the flexible driving unit, and a dynamic model of dual-driven working mode was established in MATLAB/Simulink to investigate the influence of preloading coefficient and initial preloading force for design and optimization of stick-slip actuator. Further, a prototype was fabricated and experiments showed a maximum rotary speed of 48.3 mrad/s and loading capacity of 98.8 mN center dot m for the rotary platform.

Summary: The magnetic flux density method is suitable for monitoring wall thinning in pipes. However, quantifying gradual reduction is challenging due to the small signal being hindered by noise in magnetic field measurements. This study presents a high-precision instrument for accurately measuring small thickness reductions. By optimizing the size of the magnetizer and using an ultrahigh-sensitivity magnetometer, reliable and reproducible measurements can be achieved.

Summary: The traditional Allan variance cannot reflect the time-varying characteristics of random error signals, and the dynamic Allan variance cannot simultaneously guarantee both the signal dynamic tracking performance and confidence of variance estimation. To address these issues, a dynamic Allan variance analysis method with adaptive window length is proposed, which achieves high-precision online compensation for the time-varying random error signals of optical gyroscope.

Summary: This study investigates the innovative variable rotational speed method for rotary friction welding (RFW) of polyetheretherketone (PEEK) polymer rods. The results show that the average bending strength of the welded part using a three-stage transformation rotational speed is enhanced by about 140% compared to a rotational speed of 1000 rpm. Additionally, the proposed computer numerical controlled RFW with variable rotational speed reduces the cycle time by approximately 6%.

Summary: The ability to tailor the energy band lineup of semiconductor materials plays a crucial role in the development of various electronic and optoelectronic devices. A new method based on strain engineering has been developed to introduce controlled variations in bandgap energy with lateral position in thin films, allowing for more flexibility compared to traditional heteroepitaxy. These strain-engineered samples have the advantage of a single chemical composition, unlimited choice of compatible materials, and the ability to pattern energy band lineups in arbitrary shapes through nanolithography, making them attractive for a wide range of device applications requiring complex heterostructure lineups.
