Structural Analysis
Structural analysis is to quantitatively verify deformation of structures and find out failure parts when some loads are applied. We use Finite Element Method (FEM) to confirm the strength of structures in various phases such as designing plant equipment, evaluating the soundness of old equipment, trouble shooting, etc.
We have experienced various types of Finite Element Analysis (FEA) and have accumulated knowledge and know-how on analysis and evaluation for designing a safer and more economical plant.
Capabilities
Structural Analysis and Evaluation
Along with advances in analytical technology and CAE environments, we analyze piping components such as flanges in more detail, and model the entire equipment including the internal structure to analyze its behavior accurately. We are responding to various needs such as construction work procedures, construction methods, and Fitness-For-Service (FFS) of plants that have been used for many years.
Fatigue evaluation
If the equipment or piping vibrates, or if the temperature of the structure changes during operation, it is necessary to check the strength against fatigue damage. We are conducting high-precision design and problem solving using temperature distribution obtained from CFD(Computational Fluid Dynamics).
Crack Analysis
When a crack occurs in the equipment, it is necessary to check how much allowance is available before the crack propagates and opens. We conduct Crack analysis based on Computational Fracture Mechanics (CFM) and estimate its remaining life.
Vibration analysis
Vibration of plant equipment and structures may cause serious troubles in some cases. We effectively design anti-vibration measures at the design stage or operation by analyzing with a whole model including piping, support, equipment, and frame.
Strength evaluation of piping systems
For high-temperature piping systems with complicated shapes and structures, an appropriate support arrangement is required. We analyze piping systems and evaluate the soundness using simplified piping system program.
