About

Zheng Jiaqi is a mechanical engineer whose research focuses on the precision mechanics of harmonic drives, particularly the flexible bearing—a critical component in industrial robots and automation equipment. His most-cited work, a 2020 study on the static and dynamic mechanical characteristics of flexible bearings in harmonic reducers, has garnered 12 citations and establishes a theoretical model for contact forces between rolling elements and the outer ring. This contribution addresses a key challenge in transmission accuracy and fatigue life, directly supporting the reliability of high-precision robotic joints. By combining theoretical modeling with dynamic analysis, Zheng’s research provides foundational insights for optimizing harmonic reducer performance, a cornerstone of modern automation. His work is especially relevant for engineers and researchers developing next-generation industrial robots, where even minor mechanical improvements can yield significant gains in operational precision and durability.
