Abstract
This paper discusses the effectiveness of four simulation methods used to simulate electronic control unit (ECU) drop test. Explicit and Implicit simulation methods are considered in this study. Under implicit simulation technique full transient, steady state static and mode super position methods are studied and they are compared with explicit method. Explicit simulation method is conditionally stable whereas implicit methods are un-conditionally stable, this makes the explicit method computationally costlier and time consuming. Convergence and absence to capture the dynamic response are the major challenges in implicit method. For this study the electronic control unit is simplified with bare printed circuit board (PCB) and frame for drop simulation. PCB in-plane strains and displacements are evaluated for one meter height drop on rigid floor and all corresponding results are compared to find the effectiveness of each method.
