Chain models are among the largest and most complex that can be simulated with multi-body technology. First, depending on the chain length, the number of moving bodies could become remarkable. Second, contacts disturb the solution all over the chain, causing continuous impulsive excitation of the mechanism. Third, chain links are bodies with reduced inertia, whose motion is driven by stiff contacts and stiff bushings. RecurDyn has built its reputation on chain application. The main reason is its hybrid solver, which uses an innovative approach with respect to its competitor. Even chain models featuring hundreds bodies and thousands contact points can be simulated in a reasonable time.
