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.

How does Structural Analysis Fit into you Engineering Efforts

To Win and Succeed in the Market competition, Seasoned FEA Consultants and Engineering Businesses Presently Require to Create products that are innovative and high quality, yet Profitable. Completing this requires good Choices during development, and supporting design decisions drives many FEA Consulting Services Enterprises to make investments in the design Workflow. FEA Structural Simulation Software tools enable Structural Engineering Services companies to efficiently make better decisions about cost and quality. They also Lead decision-making around experimentation, which leads to greater innovation. 
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

Identifying the Best Performing Design Through FEA Structural Analysis

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.

FEA Structural Simulation Analysis of Automotive Spoiler

1. Objective:
The purpose of the project was to analyze and acknowledge the nature of airflow and the effects of spoiler on the performance of Honda City.
The objectives are:
  1. To identify the nature of airflow over Honda City GM 6 sixth-generation car model using the Computational Fluid Dynamics (CFD).
  2. To analyze the effect of the spoiler design and position on the aerodynamic performance of Honda City GM 6 sixth generation.
  3. To generate a better spoiler design according to the downforce which will in effect minimize the drag force.
  4. To increase the stability of Honda City GM 6 sixth generation by getting the suitable design spoiler from this research.
2. FEA Simulation Methodology and Approach:

Second, Identification of geometries and parameters for model.
Third, created
CAD Solidwork geometry for Model
>Scale of Honda City
>Spoiler Design 1 Manipulating Height (3 cases)
>Spoiler Design 2 Manipulating Angle (3 cases)
>Spoiler Design 3 Correlating Height and Angle (3 cases)
Fourth, Identify the nature of airflow over the car model using CFD.
Fifth, analyzed the effect of the spoiler design on aerodynamic performance.
 
3. Outcome & Conclusion:
The coefficient of drag for the spoiler which altered with height is higher compared to the other spoiler design and vehicle without spoiler as well. From the result, it gave us a better understanding of the effect of spoiler in terms of aerodynamic which included lift and drag coefficient. Having more negative force than having less drag can be more important for passenger cars since driving safely is always the number one priority.
This fact should be kept in mind that; achieving the benefits of a rear spoiler is usually only realized at high speeds. In most cases, a spoiler may actually negatively impact the performance of a car, usually at low speeds.
