Project Brief
This case study details the comprehensive shock response spectrum (SRS) analysis conducted on the Short-wave infrared assembly. Utilizing the finite element software, we evaluated structural forces, stresses, and displacements to ensure the assembly could withstand specified shock inputs. The analysis provided critical insights into the structural integrity and resilience of the Short-wave infrared assembly under shock conditions.
Challenges and Objectives
The client required an in-depth shock analysis of their Short-wave infrared assembly to determine if it could endure the specified shock inputs defined by the shock response spectrum (SRS). The key challenges included:
- Handling a pre-meshed model received from the client, ensuring it met all necessary analysis requirements.
- Fixing the structure accurately at the flexure interface plate to simulate real-world conditions.
The primary objective was to validate that the Short-wave infrared assembly could withstand the shock requirements without experiencing structural failure.
Methodology (Solutions Implemented)
Our approach began with receiving and verifying the pre-meshed model from the client. The following steps were implemented to achieve the analysis objectives:
SRS Data Conversion: Convert the shock response spectrum (SRS) data into suitable inputs for Finite Element Analysis (FEA), either in time-domain or frequency-domain.
Load Representation: Represent the converted SRS data as an equivalent load case or time-dependent load function in the FEA software.
Benefits (Results Achieved)
The SRS analysis provided significant benefits, including:
- Validation of Structural Integrity:
- Stress Analysis: Revealed that the stresses within the assembly were within the permissible limits, ensuring no risk of structural failure.
- Displacement Analysis: Confirmed that the displacements were minimal and did not compromise the assembly’s functionality.
- Enhanced Confidence in Design:
- The analysis validated the client’s design assumptions and provided a robust confirmation that the Short-wave infrared assembly could endure the required shock inputs.
Summary of Project
This case study highlights the successful application of shock response spectrum (SRS) analysis on the Short-wave infrared assembly. By addressing the client’s challenges and meeting the objectives, we provided a thorough validation of the assembly’s capability to withstand specified shock inputs. The comprehensive analysis, supported by precise data and clear conclusions, reinforced the structural integrity of the Short-wave infrared assembly, enhancing the client’s confidence in their design and its real-world applicability.
