RecurDyn's Static Solver allows the stable and accurate Static Equilibrium State calculations of both Rigid and RFlex bodies.
Based on the N-R Static solvers, RecurDyn's Static Solver can be used for FEA static analysis as well as quasi-static analysis using MFBD technology (referred to as FFlex Static).
FFlex Static can quickly and accurately perform static analysis of nonlinear MFBD models involving contacts.
- By calculating the initial equilibrium state of a model such as vehicle or excavator in advance, the simulation speed and accuracy can be improved.
- Total simulation time can be reduced by tuning a model through static analysis before dynamic analysis.
- When the effect of inertia is small, the behavior of the model can be quickly observed using quasi-static analysis.
- It is possible to investigate the system’s range of motion or the interference between bodies through static analysis.
RecurDyn's static solver can solve the equations of motion for static, quasi-static, and dynamic simulations using the same model.
- Structural analysis of flexible bodies can confirm deformation and stress in a static state.
- Supports both static analysis and quasi-static simulation of an MFBD model considering not only self contact of FFlex body but also contact with other bodies.
- When a deformed shape of a flexible body is required, it can be obtained by using static analysis or quasi-static simulation and extracting the results.
Application Examples of static / quasi-static simulation
<Calculation of tensioned state using static analysis >
<Track link test using static analysis>
<Structural analysis of a chassis>
<Initial equilibrium state of a vehicle>
<Behavior investigation using quasi-static analysis>
Quasi-static analysis is useful when the system operates at a relatively slow speed, minimizing the impact of acceleration and inertia. With quasi-static analysis, the transient behavior of the MFBD model can be quickly analyzed. Additionally, quasi-static analysis enables the determination of the system's equilibrium states under various conditions, including different force conditions or system postures.
