Analysing problems in the event of functional deficiencies in gearboxes
- Use of special measurement and analysis techniques
- Use of special test benches and test specifications (conditioning)
- Simultaneous, complementary use of calculation tools and tests
The tools and processes of the functional development enable problems to be analysed effectively, in the event of functional deficits, which only become apparent during application at the customer. In the first instance, the vehicle’s functional deficit is transferred to a gearbox test to define and make it possible to test a functional deficit or a new functional target for the gearbox. The development of a suitable test and measurement specification and test equipment may be required. The intention is to verify the necessary function to the required accuracy.
Influencing parameters for the functional targets concerned are devised and investigated for the functional target with the help of special measurement techniques and/or computer models. Design alternatives can be run through based on an understanding of causal relationships involved in the gearbox’s functional deficit, which are implemented with the help of simulations and tests. The calculations and tests should be used in addition, so that the benefits can be used to positive effect.
Based on the definition of the solution concept for the gearbox, a critical investigation of all previously achieved gear targets is generally required, as the necessary changes may also have a bearing on these.
