FEA Stories from SIMLab-WCi
Empowering our customers to reduce or even eliminate physical lab testing of their equipment and their shipping case solution. SIMLab-WCi will optimize and validate shipping case designs to meet very critical, custom requirements and desired factor of safety.
Global Aerospace and Defense Technology Company
OBJECTIVE: The client requested a proof load of 1750 lb. while keeping the cost down.
FEA APPLIED Our simulation engineer ran the static simulation for when the shipping case is resting on the floor as well as with forklift gravity application.
RESULTS: Our simulation study successfully validated the load-bearing capacity of the case for the specified requirements with a minimum factor of safety of 1.
Global Aerospace and Defense Technology Company
OBJECTIVE: The client requested a proof load of 8,225 lb. with a vertical g acceleration of 3.3; a combine remote vertical working load of 2,500 lb. with a vertical g acceleration of 1.5 and a lateral load of 3,752 lb. with a lateral g acceleration of 1 for both constraints' conditions of when the shipping case is resting on the floor as well as when a forklift is used to lift the case.
FEA APPLIED Our simulation engineer ran the static simulation for when the shipping case is resting on the floor as well as with forklift gravity application.
RESULTS: Our simulation study provided valuable insights. In the first load case, our design was not safe as the simulation results yielded a minimum factor of safety of less than 1. The case was able to sustain the loads in the second loading scenario with a minimum factor of safety of 2.
Medical Device Manufacturer
OBJECTIVE: Our client wanted to confirm the stacking capabilities of their shipping cases; how many of each shipping case could be stacked.
FEA APPLIED Our simulation engineer ran simulated proof load analysis for multiple stacking scenarios.
RESULTS: Our simulation study validated that the client could stack 4 of the cases with an acceptable factor of safety. FEA allowed us to see how stresses develop across the model, hence validating the design based on the given requirements. FEA allows for multiple iterations and gives us deeper insights into many factors that will not be caught in a physical lab analysis.
Medical Device Manufacturer
OBJECTIVE: Our client asked for validation that their shipping case's easy loading ramp could handle their 600 lb. device and their team member loading it.
FEA APPLIED Our simulation engineer ran a simulated proof load analysis.
RESULTS: After a thorough investigation on the loading conditions and viewing the results plot, our simulation engineer was able to determine regions in the geometry where the stresses in general were far below the yield stress of the material. We were able to validate that the ramp could withstand a load of 600 lbs. based on the minimum response of the structure.
Global Aerospace and Defense Technology Company
OBJECTIVE: The client wanted to know if they could stack 2 high of their large shipping cases, loaded.
FEA APPLIED Our simulation engineer ran the static simulation.
RESULTS: Our simulation analysis gave us clear stress data that confirmed that they could stack their cases confidently 2 high.
International Technology Company & AI Developer
OBJECTIVE: The client asked to validate the weight bearing capacity of each rack rail mount, to ensure that the case would meet their requirements.
FEA APPLIED With the help of numerical simulations, our engineer was able to run the proof load simulation studies.
RESULTS: Our simulation engineer was able to validate our shipping case design against their criteria and gave our customer more confidence in their shipping case solution.
