Perform Finite Element Analysis (FEA) random vibration analysis on a given vehicle Rear Fog Lamp assembly. This task involves simulating the lamp assembly under a range of operational conditions to predict maximum stress and estimate the fatigue life of the assembly.
In this analysis, the FEA model of the Rear Fog Lamp assembly is subjected to random vibration loads, mimicking the vibrations the vehicle would experience during regular use. The objective is to understand how the lamp assembly behaves under these conditions and whether it can withstand these stresses over its expected operational life.
Temperature plays a crucial role in the performance of the assembly. As such, the analysis is conducted at three different temperatures, -40 degrees C, 23 degrees C, and 50 degrees C, to evaluate its resilience under extreme cold, normal, and hot conditions.
The stress analysis provides insights into the areas of high stress within the lamp assembly that could be susceptible to failure. Predicting the maximum stress helps in assessing the structural strength of the lamp assembly and its capacity to resist failures.
Fatigue life estimation is an important aspect of this analysis. By evaluating how the stress levels evolve under repeated vibration cycles, we can estimate the number of cycles the lamp assembly can withstand before failure due to fatigue occurs.
By fulfilling the requirement of the test, it verifies that the lamp assembly can withstand vibration testing and meet all acceptance criteria. This FEA random vibration analysis is crucial for ensuring the long-term reliability and performance of the Rear Fog Lamp assembly, ensuring it can function effectively under different environmental conditions and vehicle vibrations.
