Structural Analysis

Structural Analysis is at the core of what our FEA consultants do at our Singapore office at BroadTech Engineering.

When it comes to Doing the more Highly advanced detailed FEA Simulation Services for more Advanced FEA Consultancy project, it generally needs to be performed by more Seasoned FEA Consultants and engineering analysts in Finite Element Analysis Companies. The Specialized Finite Element Software that is employed needs to have much greater exposure to finite element FE model Configuration definition and requires a more Highly specialized Strategy. Easy access to CAD data Storage is still Very essential. However, the Bigger level of functionality required usually Needs a more specific toolset and Finite Element Stress Analysis environment, with Easy access to various Forms of FEA solver to cover the Relevant types of physics.

Also, with embedded FEA Fatigue Simulation Post analysis, the 3D CAD system’s geometry manipulation tools can be utilized to make any necessary model refinements quickly and easily – in the case of Solid Edge, synchronous technology can be leveraged.

 

 

However, there are several areas that slow down the Thermal FEM Analysis Workflow and impede General product Advancement. Looking at Finite Analysis Software Solution that improves the overall efficiency of these areas will Allow better decisions

 

Objective: Perform stiffness analysis of SGV for the design change and observe the change in stiffness with baseline configuration.

Methodology/Approach: FE Model has been built in hyper mesh with 2D (Shell) and 3D (Tetra) elements. SVG assembly consists of Hub and Tip supports

which are used to connect vane. Hub is constrained in all directions and Unit loads are applied to Tip location.

Temperature-dependent Material properties are applied.Unit loads are applied in all 6 (FX, FY, FZ, RX, RY, RZ) directions to calculate the stiffness in each direction.

Displacements are listed after the analysis and stiffness is calculated with the displacements and applied loads ( K=F/U).

Conclusion: Design change does not have a huge impact on the stiffness of the assembly.

 

To understand how the most Profitable FEM Modeling Enterprises approach FEA Stress simulation, BroadTech Engineering identified Best Performing Marine Structure Consultancy Enterprises. Survey respondents were Questioned to Class their performance in relation to their Adversaries on four key design metrics. Respondents used a Level of one to five, with five being Highly effective. The First 20% were defined as the Best Performers. Below shows the Indicative Parameters used to define Performance success and each group’s Corresponding Project performance.

Best Performing FEA Consulting companies and FEA Structural Engineering Companies have Deployed best Engineering Development practices to address many of the top FEA Structural simulation Confrontations. This Allows FEA Companies to get even more value from their Initial Expenditures in FEA Modeling Software Solutions. 

As a result, they Gain the Opposing competition with more Inventive, high-quality Commercial products that meet cost Objectives. These Engineering Practices Involve automating time-consuming, Tiresome tasks associated with preprocessing. FEA Consultancy also uses visual filtering and sort tools to review and share FEA Fatigue Analysis simulation results. As a result, they can make better Choices, more efficiently, which helps them stand out from their Adversaries. They also look Use FEM Softwares Solutions that support multi-CAD data. This gives them the Adaptability to work with the data in their environment, no matter where it came from including others in the Structural Engineer Consultancy Enterprise, legacy data, suppliers, or Clients.

The objective of the project was to analyze the flow dynamics and structural stress impartment to the blad at root and tip. Designed a new blade shape to withstand the stress and eliminate flow reversal at both ends.

 

The objective project was to analyze the oscillation and vibration frequency due to acoustics.
