Automotive. CompMechLab Experience
In order to be able to meet customer's requirements for shorter development times, CompMechLab's development process takes the form of Simulation Based Design engineering. The application of CAE methods allows our simulation specialists to set the direction in the early stages of development for achieving the functional objectives in a range of areas: Crash Analyses, Occupant Protection, Strength Calculations, Rigidity Calculations, Vibration, NVH, CFD Simulation, Thermo-Mechanical Analyses and others.
Crash analysis: Implementation and Methods
Finite element model development and simulation based design for complete vehicle.
CompMechLab develops vehicle bodies for the automotive industry, in the frames of the high standards of functionality requirement. Development includes the passenger cell, floor pan, front-end structure, roof module and closures. The responsibilities of the body development include the precise definition of the strength, rigidity and crash behaviour of the bodywork.

Virtual Crash Test Dummies: A Data Management TestUsing its SLM tool to automate and manage huge data sources, SIMULIA accelerates the qualification process for its Abaqus FEA crash test dummy models from weeks to days.
Physical crash dummies may have dozens of sensors and other sophisticated mechanical parts, but their digital brethren can be just as complicated. With more than 100,000 elements and dozens of validation tests to manage, companies delivering the complex FEA simulation models that lie at the heart of the virtual crash test dummies are starting to leverage a new type of software platform to facilitate the process.
