The nomenclature of test rigs is extensive enough, and, therefore, the equipment line-up is pretty diverse. Virtually all the manufactured products pass a particular control, characterised by various complexity and applied in serial and mass production. More importance is attached to test rigs in individual, pilot and small-scale production and (air tooling in particular).
A normal test cycle can be divided into three stages. The first stage, test preparation, implies defining of the objectives; selecting or designing the required test equipment and its manufacture; measuring equipment selection; products preparation (locations designed to accommodate the equipment revision); preparing technical documentation. The second stage is about actual test, and the third one is processing experimental data and the test results formulation.
When testing complex products or systems, it is necessary to receive and process a large amount of information on the various parameters (the total number of parameters may equal several thousands of items). The laborious process rests on the shoulders of a large amount of qualified technical workers. Thus, the use of information-measuring systems for automated test rigs is a challenge yet to be leveled.
In addition, during testing the equipment is adjusted (i.e. regulate its parameters), which implies managing the testing process. To perform the operations mentioned above, test rigs are equipped with automated systems.
Natural rigs testing is particularly vital in various researches conduction and upgrades development. Despite the fact that they extend the process of designing, making it more costly at the same time, the procedures guarantee a high level of reliability and optimality of methods used.
