Modal Analysis and Testing of Large-Span Space Steel Structure
Large-span space steel structure, rotary hearth furnace lower ring, has dynamic stress at work caused by shock or vibration leading to the destruction of steel, so in the design of rotary hearth furnace lower ring, dynamic design is an essential part [1, 2]. Finite element analysis software ANSYS is used to build its finite element model. Modal analysis is carried on, and experimental data is compared with the calculation result, which effectively estimates the vibration characteristics and structural optimization design of the structure, and provides strong technical support for its design and manufacture[3, 4].
