Finite Element Analysis

An important consideration for many off-road applications is the high levels of thermal and mechanical stress on a catalyst or muffler. DCL conducts vibration testing for many off-road applications and uses FEA to assess a new design for thermal and mechanical stress. This allows correct mounting procedures to be established and ensures the designs will work without premature field failures.
