Q. We are interested in design information regarding welded tube steel roll bars and cages. Are there design sources or standards regarding this topic? (Submitted by: Jeff Van Leuven from Unknown)


A. If I understand your question, you are looking for roll cage design? Most sanctioning bodies dictate the roll cage design for a particular series. Take NASCAR for example. Beyond the driver's compartment, there is usually some leeway in bar placement. NASCAR dictates bar thickness and placement. The teams are allowed to fix the suspension points where they want. As far as standard design kits or basic cages, pick up a racing magazine. They usually have some advertisers that carry cage kits.
Hope this is what you were looking for.
