Cost-effective safety design software

Simcenter Madymo is the worldwide standard software for analyzing and optimizing occupant and pedestrian safety designs. With pre- and even non-crash scenarios analysis becoming more important for occupant safety, the number of relevant loading scenarios is growing rapidly and the duration of simulated events is increasing. Simcenter Madymo combines multibody, Finite Element and CFD technology integrated in one single solver, with the right balance between accuracy and speed. It includes a database of extensively-validated crash dummy models and human body models. Using Simcenter Madymo, researchers and engineers can model, thoroughly analyze and optimize safety designs early in the development process. This reduces the expense and time involved in building and testing prototypes. For new or improved vehicle models and components, Simcenter Madymo cuts costs and reduces the time-to-market substantially. It offers unparalleled accuracy, efficiency and versatility.

MADYMO Coupling

PSA Peugeot Citroën

" With the usage of coupling, PSA managed to gain considerable time saving in vehicle developments. The Radioss-MADYMO coupling solution enables PSA to use the same MADYMO dummy and restraint models in occupant safety analysis as well as in the RADIOSS structural analysis. This removed the need to create intermediate FE models of the restraint system, which has lead to reduced development time and higher confidence in simulation results. "

Multibody - Rigid body dynamics

The Multibody systems are part of the Simcenter Madymo Solver. This is a flexible multi-physics simulation engine that uniquely combines the capabilities of multibody (MB), finite element (FE) and computational fluid dynamics (CFD) in a single CAE solver. The Multibody systems can be described as rigid or deformable bodies, interconnected by kinematic joints. Geometrical, material and contact properties can be assigned to the bodies to capture the physics of the system modelled. This computationally fast method of modelling complex dynamic systems is particularly well suited for performing large parametric design studies.

Finite element analysis

The Finite elements are part of the Simcenter Madymo Solver. The Simcenter Madymo Solver is a flexible multi-physics simulation engine that uniquely combines the capabilities of multibody (MB), finite element (FE) and computational fluid dynamics (CFD) in a single CAE solver. Simcenter Madymo’s explicit transient finite element (FE) solver includes an extensive selection of element definitions, material models, and contact algorithms. Simcenter Madymo FE allows for detailed modelling of deformable structures inside the occupant compartment, such as seatbelt, airbag, seat and trim.

Computational fluid dynamics

The computational fluid dynamics module are part of the Simcenter Madymo Solver. The Simcenter Madymo Solver is a flexible multi-physics simulation engine that uniquely combines the capabilities of multibody (MB), finite element (FE) and computational fluid dynamics (CFD) in a single CAE solver. Engineers use Simcenter Madymo’s computational fluid dynamics (CFD) module to carry out detailed modeling of the flow of fluids, such as gas flowing inside a deploying airbag. Simcenter Madymo Gasflow is used to simulate Out-of-Position events where injuries can result from contact between the occupant and a deploying airbag.

Simcenter Madymo coupling

The coupling of Simcenter Madymo with FE codes enables safety designers to embed its models of the dummy and restraint system in their preferred FE crash code. The combined result of the calculations performed in Simcenter Madymo and the FE crash code can be visualized and post-processed in a single graphical tool. Today, coupling is available between Simcenter Madymo and LS-DYNA, PAM-CRASH, RADIOSS and ABAQUS. This enables engineers to use Simcenter Madymo crash test dummies, which to date remain the fastest and most accurate dummy models available, in their preferred FE code. MATLAB coupling also allows engineers to include control algorithms and evaluate their effects on the restraint system.

Simcenter Madymo dummy models

Years of research and development have led to the creation of the most extensive database of crash test dummy models available. Simcenter Madymo Dummy Models are famously accurate and also renowned for their computational speed, robustness and user-friendliness. Simcenter Madymo provides dummy models that meet the most stringent demands for accuracy, robustness and computation speed.  The Simcenter Madymo dummy models are validated on component, assembly and full-system level using an extensive database of test data. The Simcenter Madymo crash test dummy models have been successfully applied in the analysis and design of a wide range of protective devices, ranging from Automotive, Aviation, Defense, and Rail.
