Economic history of South Africa The formal economy of South Africa has its beginnings in the arrival of Dutch settlers inoriginally sent by the Dutch East India Company to establish a provisioning station for passing ships. As the colony increased in size, with the arrival of French Huguenots and German citizens, some of the colonists were set free to pursue commercial farming, leading to the dominance of agriculture in the economy.
The South African subsidiary has been successfully involved in rally racing South africa a case study analysis 27 years, with its Volkswagen rally team taking home the top prize for six years in a row.
Rally racing is a type of auto racing that uses modified or specially built road-legal cars. The course can be anything from a paved road to gravel track to a dirt path, or any combination of those, and it is not a circuit but a stage-to-stage format.
Another aspect of rally racing that makes it challenging is the extremely limited amount of time available for fixing things that go wrong, or things that the drivers want changed, between race stages.
Even during the off-season, the designers and engineers feel pressure to work rapidly, due to the extent of the changes they need to make to the car.
One aspect of NX, synchronous technology, is especially valuable to the team because of how quickly it allows changes to existing computer-aided design CAD models. Designers use this technology in conjunction with the kinematics analysis and finite element analysis FEA of NX Advanced Simulation to quickly evaluate different assembly configurations.
For example, there are places in the front-end assembly where the clearance is just a few millimeters, and the team needs to be sure this will be sufficient during a race. They can run the assembly through its range of motion using kinematics analysis.
Then, if they see a problem, they can quickly change the geometry using synchronous technology, update the FEA model and repeat the analysis. When this process showed an interference between the wishbone and steering rod, for instance, it took only five minutes to revise the digital assembly and analysis model before they were ready to run another analysis.
The process works similarly with FEA.
In the example with the wishbone and steering rod, the designer actually had to cut a notch out of the wishbone to prevent interference with the steering rod. With FEA results to guide him, he could design the notch in such a way that the wishbone was still strong enough to handle the extreme loads it would be subject to in a race such as a 5g bump.
In another example, the team needed to design a new transmission mount. Use of NX has been helpful on the manufacturing side as well. Manufacturing engineers can clearly see the parts they will be making.
In addition, because of the analysis that has been done before the designs reach manufacturing, there is no worry that parts will not fit.
Using Teamcenter to manage it all An important part of making changes to the car so rapidly is making sure everyone involved knows what they need to do and when, and has the information they need to do it.
That is where Teamcenter comes in. The rally team runs NX within the Teamcenter environment, which manages all of the information related to the vehicle.
This includes the CAD data, drawings, analysis results, bills of materials, and so on. Use of Teamcenter also enables VW Group South Africa — Motor Division to control access to vehicle information so that multiple people can work simultaneously on the same change.
It enables them to be confident that they are working with up-to-date CAD data. The team uses Teamcenter to keep its suppliers and sponsors included in the process as well.
The efficiency the team gains from using NX and Teamcenter gives them extra time to make sure that changes are correct the first time, which has certainly contributed to its outstanding success.The South African renewable energy independent power producer procurement (REIPPP) program is not only the largest RE program in Africa, but the largest independent power producer (IPP) program of any African country and probably the most complex public-private procurement ever run on the continent.
