Transportation Analysis -Keeping Things “In-Their-Place” Whether Over Land, Sea, Air or Space

Objective
We hope you enjoy this tour of our FEA consultants experience in strapping, chaining, bolting, seat-belt’ing objects for all sorts of transportation incidents.
Welcome to our overview of Predictive Engineering’s FEA nonlinear consulting services for transportation simulation. Over the years we have analyzed the transport of cargo, jet engines, pressure vessels, humans (anthropomorphic test devices or ATD’s), composite containers, submarines and of course, electronic equipment on barges, ships, planes and rockets (space).

Keeping Things “In-Their-Place” Whether Over Land, Sea, Air or Space
Transportation Analysis – Keeping Things Attached Whether Over Land or Air
Our client was developing a new cargo strapping system to increase the carrying capacity of loose cargo per pallet and wanted to digitally prototype new designs prior to testing. Predictive Engineering’s nonlinear FEA consulting services was able to simulate several new designs quickly and send the “winner” off to sled testing at 9g.
Transportation Analysis - Land Transportation: 60 mph Barrel
Land transportation at 60 mph provides its own set of challenges; especially so in the transport of hazardous wastes. The simulation work showed that standard polyester rachet straps were not sufficient to restrain a 55-gallon drum upon deceleration from 60 mph.
Transportation Analysis - Land and Air Transportation: Jet Engine Cradle Surviving 9g Side Hit
Side impact simulation of jet engine transportation cradle: Our client was required to demonstrate that their transportation cradle could safety transport jet engine cores over land and in the air. Our nonlinear impact simulation showed that it could easily handle 1.5 g but at 9g problems occurred.
Transportation Analysis - Land Transportation: Truck Transport
Truck transport of cargo requires specific strapping arrangements per the Federal Motor Carrier Safety Administration (FMCSA) under 393.100-114 Protection Against Shifting and Falling Cargo. Our client’s strapping arrangement easily met this requirement but they were curious what would happen at emergency stops from 55 mph. Our nonlinear, transient dynamic FEA model presented clear-cut results.
Transportation Analysis - Air Transportation: ATD’s
What we know without a doubt, please keep your seatbelt fastened when you are flying. The standard 16g seat test ensures that you will stay in your seat – even if you don’t survive the crash.
Air, Land and Rail Transportation: Composite Container with Built-In Reinforcements
Composite containers provide lightweight protection for world-wide deployment of sensitive flying objects. This container was virtually tested under PSD (air transport), drop test, rail impact and pressurization analysis. Predictive’s nonlinear FEA consultants were able to demonstrate, after a few design iterations, that the container would pass all tests and it did!
