Web gateway speeds solder joint reliability predictions
Solder joints account for a huge proportion of failures in electronic systems in all industries, writes Roger Bishop. But in the automotive sector where, in terms of cost, there is more electronic content in a car than steel, long-term reliability is more than a goal. It is a requirement. |

Digital mannequins model behaviour
The latest Ramsis anthropometric software improves cabin space ergonomics using digital mannequins. Through prediction algorithms and anthropometric data, the software accurately models human in-cabin behaviour, helping refine both cabin and equipment designs.
The 3D mannequins behave like real drivers by operating controls and infotainment.

Software solves complex heat transfer issues
The latest version of CD-adapco’s Star-CCM+ computational fluid dynamics software (v2.08) has an improved meshing engine that delivers higher quality meshes up to 20% faster in some cases than its predecessor.There are also enhancements to the simulation of problems involving heat transfer between liquids, gases and solids. |

Joint data brings more reality to simulations
The correlation between computer simulations and real-life testing is improving all the time, writes Roger Bishop. But a remaining area of weakness concerns adhesive joints, rivets, spot welds and laser-welded seams for which conventional simulations do not allow for failure. They are usually assumed to be infinitely loadable. Given that a mid-size car uses about 5,000 spot welds and more than 120m of adhesive joints as well as rivets, it is a problem. |
