The Effects of Vibration on Condenser Design Simulated using FE Modeling and Validated thru’ Vibration Endurance Test and Strain Measurement Test 2020-28-0380

Vibration has many undesirable and harmful effects on life and performance of mechanical equipment and other structures. The effects of vibration are due to dynamic interaction between vehicles and road, vibration transmitted from machinery to its supporting structures thereby interfering with their performance , damage as well as malfunction and failure due to dynamic loading, fatigue failure, oscillation of transmission lines.   In this paper, numerical and experimental modal & dynamic analysis are discussed to derive the modal properties (mode shapes & modal frequencies) and dynamic properties (strains, stresses & deflections) of condenser assembly. A Finite Element Method is used to determine the natural frequency and structural integrity of the AC Condenser Assembly, whereas the experimentation's are performed using strain gauge measurement test for verification and vibration endurance test for validation. In FEM, condenser assembly is analyzed under resonance condition and improved the design at high stress area's.   The main objective of this work is to strengthen the Condenser's connector sub-assembly under dynamic load and verify the same before & after using strain gauge measurement method. After verification, validate the same with proto sample under same load conditions.   After verification & validation, correlation between numerical & experimental results is made and establishes the proficiency for all other components to mitigate the proto cost and warranty failure issues.
