Academic Background With the increasing demand for high-speed and lightweight design in the aviation industry, more and more aviation transmission shaft systems have adopted supercritical design. Supercritical design means that the drive shaft must cross its first critical speed, but when crossing the critical speed, the shaft system will produce s...

Background Introduction In aerospace engineering, thin laminated composite structures (such as wings) are prone to vibration under high-speed airflow, which may lead to instability phenomena such as flutter or divergence, affecting the safety and performance of aircraft. Particularly, when delamination (i.e., adhesive failure between layers) exists...

Parameter Identification of a Nonlinear Vertical Axis Rotating Machine: An Innovative Approach Based on Reduced Order Modeling and Data Assimilation Academic Background In modern engineering, the modeling of nonlinear dynamic systems is a crucial research area. However, such systems often involve parameters that are difficult to measure or estimate...

Research on Finite-Time Adaptive Robust Trajectory Tracking Control for Dual-Arm Space Robots Research Background and Problem With the rapid development of space technology, space robots are playing an increasingly important role in on-orbit servicing, satellite assembly, spacecraft refueling, and other tasks. However, space robot systems face nume...

Academic Background With the rapid development of wearable electronic devices, the demand for high-performance, flexible, and durable materials has been increasing. Graphene, as a two-dimensional material with excellent electrical conductivity, mechanical strength, and flexibility, has garnered significant attention in recent years for its applicat...
