Challenge

The OEM was developing an office chair  in which one major component of Backrest needed to be evaluated for structural strength and rigidity. The backrest assembly has two sub-components (back rest and J-bar). The backrest sub-assembly needed to be tested as per governing standard ‘BIFMA X5.1 – 2017’. The client wanted to analyze the backrest and optimize the design by making necessary changes in the assembly.

 

An engineering analysis of the design was required to verify design goals by leveraging the modern state of the art simulation environment. Timetooth, with its expertise in Structural analysis, partnered to assess the design & meet the regulatory standard and suggest necessary modifications.

Service Area

Engineering Simulations

Timeline

December 2022 to January 2023

Interpretation of simulation results found that J-bar and localized areas of the backrest where J-bar is mounted showed high stresses.

Key Engineering Solutions

1. Structural analysis was done to predict stress and displacement in the backrest assembly.

2. The assembly was meshed as per the benchmarked quality

3. The necessary boundary conditions and loads were mapped to analyze the model.

Solutions

Timetooth performed structural analysis to predict stress and displacement in the backrest assembly to evaluate and optimize it. The backrest assembly was then meshed as per benchmarked quality, and analyzed with the necessary boundary conditions and loads.

Further simulation results were interpreted and it was found that J-bar and localized areas of the backrest where J-bar is mounted showed high stresses. As per the assessment of simulation results specific design modifications to meet the required parameters were shared with the client.

Key Highlights

    ROI for the client

    Client was able to improve the design for meeting the governing standard before investing in physical testing.
