  • Essay / Fea analysis of the impact of Pumpkin Ball on the console

    Table of contentsIntroductionLiterature reviewValidation and conclusionIntroductionThe console is the part that creates a bridge of interaction between man and machine. The console assembly includes the HMI (human-machine interface) and the console shell. The console shell is the part on which the HMI part is mounted. The HMI (Human Machine Interface) includes the entire electronic part which includes LED bulbs, buttons, PCBs, etc. Say no to plagiarism.

So, every console design must pass certain UL tests without which the product cannot be launched in the market [1]. Among the many safety tests performed on the console, one of the most important tests is the bullet impact test. The ball is actually a basketball filled with sand up to 1/3 of its volume and impacted on the console. The test is very similar to the pendulum impact test but the only difference between the two is that the pumpkin ball is deformable upon impact, making it more dynamic and difficult to study. The need to perform the bullet impact test on the console can be understood by an instance where there is a major impact on the console directly for an unknown reason. So the full impact can damage the console. The major concern is access to the live wire after damage. The main objective of this article was to correlate simulation with experimentation. During new product development, when a console is designed, the only way to verify if the product would pass the UL standard safety test during the design phase is through simulation. Thus, the only way to understand the accuracy of the simulation is to study the behavior of the console when impacted by the ball and compare it with the real experience using an accelerometer.Review of the literature where S. Sridhar and Sushilkumar Vishwakarma worked on modeling the behavior of dry sand with DEM for better impact prediction with the aim of creating a standard simulation model that would capture the behavior of a ball filled with sand particles when it is impacted on the concrete wall and would validate it with the experimental model. The simulation results showed a close proximity to the experimental results [2]. Hamidreza Mahmoudi worked on hood modeling in LS-DYNA for pedestrian research trying to propose a finite element model for pedestrian kinematics analysis using LS Dyna and hypermesh software. The maximum acceleration and duration of the impact were used for comparison with the experiment [3]. Edwin Fasanella and Karen Jackson worked on describing best practices for aircraft impact modeling using explicit nonlinear dynamic finite element codes such as LS-Dyna. In accident analysis, the point of greatest concern is the magnitude and duration of peak acceleration. Analysis of experimental data and digital filtering are also discussed [4]. The report of SMP Svensk on the requirements and test methods for the impact of an oscillating element for which the accelerometer is used during the experiment and the results are compared in g units [5]. Frank, Stefan and Marika worked on material models for polymers subjected to loads.
