Qiao Sun

Qiao Sun is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Qiao Sun rather than just read about it. In short: Qiao Sun is a Chinese and Canadian mechanical engineer whose research concerns the analysis, diagnosis, and control of vibrations in mechanical equipment ranging from the nanoscale of scanning probe microscopy to the macroscale of wind turbines. She is a professor in the Schulich School of Engineering at the University of Calgary, where she heads the Department of Mechanical and Manufacturing Engineering.

Key takeaways

Qiao Sun belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Qiao Sun to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Qiao Sun from memory before moving on to harder problems.

Reference excerpt

Qiao Sun is a Chinese and Canadian mechanical engineer whose research concerns the analysis, diagnosis, and control of vibrations in mechanical equipment ranging from the nanoscale of scanning probe microscopy to the macroscale of wind turbines. She is a professor in the Schulich School of Engineering at the University of Calgary, where she heads the Department of Mechanical and Manufacturing Engineering.

Education and career Sun received a bachelor's degree in power machinery engineering from Shanghai Jiao Tong University in 1982, specializing in diesel engines for ships. After a year working in a shipyard, she went back to Shanghai Jiao Tong University for a master's degree in mechanical engineering, completed in 1986. Her master's degree research concerned robotics, working on the control of the "Shanghai No. 1" arc-welding robot. Following this she continued at Shanghai Jiao Tong University as a lecturer and researcher in the university's Research Institute of Robotics. She moved to Canada in 1992 to pursue a doctorate at the University of Victoria, which she completed in 1996. After working for eight months for the National Research Council Canada in Vancouver, she joined the faculty of the University of Calgary in 1996. She chaired the Schulich School's Gender and Diversity in Engineering Committee and served as senior associate dean for diversity and equity from 2014 to 2020 before taking her current administrative role as department head.

Recognition At the University of Calgary, Sun was named the professor of the year in the Department of Mechanical and Manufacturing Engineering in 2010 and 2014, and has won multiple awards for her teaching and mentorship. She was named as an "Excellent Woman Mechanical Engineer" by the Canadian Society for Mechanical Engineering in 2014, and elected as a Fellow of the Canadian Academy of Engineering in 2021. The Association of Professional Engineers and Geoscientists of Alberta (APEGA) gave her their 2022 Women in Engineering & Geoscience Champion Award as part of the APEGA Summit Awards. She was the 2024 recipient of the Minerva Mentoring Award of the Alberta Women in Science Network.

Worked examples

Example 1 — a first encounter with Qiao Sun

Start with the simplest possible case. Write down what Qiao Sun claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Qiao Sun before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Qiao Sun ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Qiao Sun

In research: Qiao Sun appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Qiao Sun in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Qiao Sun is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century mechanical engineers, Academic staff of the University of Calgary, Canadian mechanical engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Qiao Sun outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
