Thermomechanical structure calculation for compressor bearing housing for gas turbines
Category: Engineering
Process: Development
Introduction
Various analyses which prove the strength of components under certain conditions are needed in the process of developing and producing new power plant components. The finite element method is used in this context to calculate stresses in the component. Capacity bottlenecks caused a leading company from the international power plant sector, located in North Rhine-Westphalia, to have the thermomechanical structure calculation for a compressor bearing housing for gas turbines undertaken externally.
IndustrieHansa was awarded the work on the basis of its excellent ANSYS knowledge which was absolutely essential for this work as well as its know-how in the assessment of the stresses calculated.
Solution: Undertaking of all thermomechanical structure calculations under consideration of the specified operating load and fault scenarios.
Puncture points
Operating load scenarios
Fault scenarios
Benefits
The calculations and assessments undertaken by IndustrieHansa confirmed the technical feasibility of the assembly investigated such that approval could be granted for construction of the turbine component on the basis of the computer-based analyses for the components.
