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.

A revolution in composite materials characterisationThe characterisation of a new composite material system, particularly for application to fields such as aerospace structures, is a time-consuming process costing potentially millions of dollars. This is partially due to the vast number of tests conducted with a single mode of loading in a qualification scheme. In fact, testing of materials has consistently been driven to a purity of loading mode, so that material response is easily understood and modelled. However, the costs associated with this approach provide a large barrier to the qualification of new materials. Collaborative research undertaken by the US Naval Research Laboratory (NRL) has been focused on the development of a testing system to address this barrier, utilizing a more comprehensive understanding of mechanical response of composite panels.

GM to introduce industry-first front center airbagsWith frontal, roof-mounted and rear-window airbags you'd be forgiven for thinking that there couldn't possibly be anywhere else in a car automobile manufacturers could cram one. But you'd be wrong. General Motors (GM) has just announced it will introduce the industry's first front center airbag in selected vehicles in 2013. The latest airbag addition is designed to protect drivers and front passengers in the event of side impact crashes. Read More... (Reads: 247)
