Global Manufacturer of Engine Filters Saves 3 Months and Thousands of Dollars in Cyclic Fatigue Testing Program

A globally known filter manufacturer had a fast-paced program and needed help to reduce their test program time.

Starting with a first-pass iteration of a filter canister design, Sigma engineers used non-linear plastic simulation analysis to determine whether long-term cyclic loading would be likely to cause permanent deformation, and worse yet, failure.

After further simulation review we found that there were certain areas in the molded housing that were suspect to failure. As often found in these analyses, the defects were less than obvious.

The software and Sigma’s engineering analytical skills uncovered these areas, which saved the client needed time and money. The client modified the design and went to physical testing, saving 2 to 3 weeks of iterations. This insight got their program back on track and on budget.

Sigma’s engineering experience helps product launches stay on schedule by removing the unforeseen obstacles that delay new product development progress. Our team is capable of performing Linear Stress, Non-Linear Plastic Deformation, Computational Fluid Analysis, as well as other specialized engineering software.
