The article discusses how engineers used computer simulations and physical measurements to analyze the strength and stiffness of an electric hoisting installation in a power plant. They compared the benefits of using computer models versus real-world testing, and found ways to combine both methods effectively. The researchers used a software called ANSYS for the computer simulations, which is known for its accuracy in engineering analysis. They also explored the software's strengths and weaknesses, especially in handling complex calculations and adapting to different scenarios.
