Strain-life fatigue analysis of aluminum automotive radiators
by Alexander, Brian D., M.S., California State University, Long Beach, 2009, 40; 1481606
Abstract (Summary)

The goal of this paper is to determine the optimal plastic tank aluminum radiator side-piece design using solid modeling tools and finite element analysis, (FEA). This analysis utilized the non-linear solid modeling capabilities of Algor® to identify the exact location of maximum stress. The speed and flexibility of solid modeling software provided the opportunity to quickly generate multiple solutions followed by an FEA analysis to iteratively determine the optimal configuration. The original design and the proposed optimal design could then be instrumented to measure strain as a result of application specific thermal loading. A graphical solution was then finally obtained via the strain life equation for both radiator designs allowing a predicted product life-cycle comparison based on the cumulative reversals to failure.

The results of this design optimization analysis indicate that the final radiator side-column design increases the product life cycle by 20 million cycles. Therefore one can conclude that the radiator product life-cycle can be significantly increased by computer-aided design and simulation tools concluded by a stringent design and validation testing procedure.
