Dr. Qixiang Zhang is a researcher at Southwest Jiaotong University, Chengdu, China, specializing in railway braking systems, tribology, and thermo-mechanical behavior of high-speed train components. His research focuses on friction interface evolution, wear mechanisms, vibration characteristics, and thermal crack propagation of brake discs and friction materials, particularly under extreme operating conditions such as long downhill ramps and cold environments. He has authored 36 peer-reviewed publications, which have collectively received over 503 citations, reflecting the strong academic influence and technical relevance of his work. With an h-index of 13, his contributions demonstrate sustained impact in railway engineering and mechanical wear analysis. Zhang has collaborated with more than 55 co-authors, indicating active engagement in multidisciplinary and institutional research networks. His findings support safer, more reliable, and more durable braking systems for high-speed rail, contributing directly to transportation safety, energy efficiency, and sustainable railway infrastructure development.
