Occupant and pedestrian safety are critical design aspects that determine whether a vehicle can be homologated. Therefore, thorough prototype testing needs to be done before a vehicle can go to market. However, this testing is expensive and can cause significant delays, especially when problems are discovered. For this reason, vehicle manufacturers save prototyping time and cost by doing upfront research and analysis using simulation.
Simcenter offers software solutions for occupant and pedestrian safety simulation. The software comes equipped with a wide range of human and dummy multi-body models that are used to analyze various safety critical scenarios. Due to the computational speed advantage offered by multi-body dynamics compared to finite element analysis (FEA), engineers can design safety systems in a time-efficient manner.
Get an accurate prediction of human body response during vehicle maneuvers.
Leverage the outcome of decades of research and development, bundled in one of the most extensive crash test dummy model databases available. Simcenter dummy models are known for their accuracy, as well as their computational speed, robustness and user-friendliness. The dummy models are validated on component, assembly and full-system levels using an extensive database of test data.
Simcenter crash test dummy models are successfully applied in the analysis and design of numerous protective devices in various industries, including automotive, aviation, defense and rail.
Evaluate and optimize passive and active restraint systems in a wide range of real-world loading conditions with CPU-efficient, biofidelic, and well-validated human models.
Simcenter can predict human responses to conditions that physical dummies cannot. The human model portfolio comprises both passive and active models. The models combine passive stiffness characteristics and active control to realistically represent how living humans respond. Simcenter models are multi-directional approved, allowing an analysis of more complicated scenarios. As of February 2023, they are the only human models on the market that can accurately simulate occupant behavior in pre-crash emergency braking and crash avoidance maneuvers.
Simulate out-of-position events for deploying airbags, where injuries can result from contact between the occupant and the airbag. The unique multiphysics solver of Simcenter allows you to combine explicit multibody (MB), finite elements (FE) and computational fluid dynamics (CFD) for airbag gas dynamics as a single seamless feature set.
Accurately model deformable structures inside the occupant compartment, such as the seat belt, airbag, seat and trim. Dedicated to this application, Simcenter uses an explicit transient finite element (FE) solver that includes an extensive selection of element definitions, material models and contact algorithms.
Perform extensive parametric design studies using a computationally fast method for modeling complex dynamic systems. In Simcenter, you can describe systems as rigid or deformable bodies interconnected by kinematic joints, and you can assign geometrical, material and contact properties to capture all of the physics.
Couple Simcenter with other popular finite element (FE) codes for safety design so you can leverage the Simcenter fast dummy models with your preferred FE solutions. You can also connect with MATLAB to include control algorithms and study their effects on the restraint system. Simcenter supports these FE codes:
Integrated safety systems are a combination of passive and active safety systems that aim to improve pedestrian and occupant safety.
EDAG Group uses Simcenter Madymo to speed time-to-market for new pedestrian safety systems, reducing simulation time for human body behavior from days to hours.
