Accurately predict complex nonlinear specimen behavior to increase multiaxial durability test throughput, protect specimens, improve test correlation - and accelerate vehicle development.
In durability testing, traditional RPC iteration struggles when navigating the highly non-linear behavior of jounce bumpers and elastomeric bushings and mounts. Standard frequency response functions are intended primarily for linear behavior. When a specimen’s stiffness curve hits an abrupt corner — or “hockey stick” — convergence can fail, iterations multiply, and specimens take a beating. Available exclusively in RPC Connect software, new NonLinear Navigator (NLN) enables you to overcome this problem by predicting abrupt stiffness changes before they throw convergence off course — even in multi-axial tests — cutting iteration time by up to 50%, protecting specimens from overloading, and delivering results you can trust.
NonLinear Navigator characterizes a specimen’s nonlinear stiffness profile and predicts exactly where that stiffness transition occurs — then linearizes the drive correction across all active axes before the overloading engagement occurs.

Less Iterating: proven effective in reducing iteration times by up to 50%, NonLinear Navigator accelerates multiaxial durability test convergence and increases test lab throughput.
Less Overloading: NonLinear Navigator minimizes overloading events to safeguard the integrity of components, subsystems, and vehicles for the full duration of rigorous durability testing.
Better Results: Easily integrated into existing workflows, NonLinear Navigator improves correlation across all degrees of freedom, yielding increased confidence in multaxial durability test data.
