By means of comparing critical drop height acquired from test, the feasibility of this tool chain simulation is shown.
Product drop test standard height guidelines vary depending on factors such as the nature of the product, its fragility, and the intended mode of transportation. For instance, delicate electronic devices may require lower drop heights to assess their susceptibility to damage, while robust industrial equipment may necessitate higher drop heights .ISTA 4 Series: Project-specific advanced simulation test procedures for products and packaging in their anticipated transport environments. . Conducting the Drop Test: A drop testing machine or a free-fall method is used to ensure precise and repeatable drops. The method of dropping (manual or mechanical) should align with the standard being .

The Drop Test Setup PropertyManager allows you the following options to setup the drop test study: . You define the drop height (h), the acceleration of gravity (g), and the orientation of the impact plane. The program calculates the velocity (v) at impact from: v = (2gh) 1/2.The body moves in the direction of gravity as a rigid body until it hits the rigid plane. This tutorial video we will learn how to make a Simple Mug Design and drop test on simulation.If you like, subscribe our channel for more videos and projects.A consumer electronics drop-test case study is presented to demonstrate a methodology to rapidly obtain high-accuracy results from an explicit analysis using submodeling. . Simulation Workflow 1. Geometry: Import CAD and prepare for analysis using ANSYS DesignModeler. 2.Example showing a drop test load case. A deformable body is dropped on a rigid wall.
Due to the nature of event simulation, the simulation needs to have a small duration (such as 0.001 seconds). With this being said, a full drop test cannot occur with this duration. Instead, the item of interest is the impact. The initial conditions can be set to simulate that aspect. Calculate the velocity of the falling object just before impact. This study used finite element analysis software ANSYS/LS-DYNA to perform a drop test simulation of test board under JESD22-B111 standard, with 0.5ms pulse duration time and 1500G peak .
Drop Test Simulation for Designers. In the past – in order to perform a finite element simulation – an expert analyst would have to manually walk through the steps of finding and cleaning up the geometry, seed and mesh the parts, define boundary conditions for the simulation, perform the solve and iterate.
