GD -Turret Drive Test System
V I Engineering, Inc., a National Instruments Select Premier Alliance Member, was contracted by General Dynamics Land Systems to replace an automated end-of-line test stand to aid in the critical test requirements for validating turret drive assembly units for various military land vehicles. Turret drive assemblies are used in military vehicles for gun elevation, tow lift, and traverse drives, which regulate the control of mechanical operations. There are a maximum of twelve different tests that can be performed using this software package. The type of tests available to the operator are dependent on the type of turret drive that has been selected to be tested. The software has the capability of testing 7 different turret drive types, each of which can be have any of two motor types.
The system required a password/login utility for controlling and limiting access to specific functionality of the software, along with identifying current and former users within the report generation. The comprehensive testing includes calculating testing parameters with respect to distinct turret drive units, executing a maximum of 12 distinct tests, analyzing and data processing of each test, limit checking, printing pass/fail reports, and archiving the reports and test data. The software must be capable of running with minimal user intervention and intelligent enough to give user directed instructions for correct operation and testing. All test stand software packages that have been developed by V I Engineering, Inc. for General Dynamics have an analogous "look and feel"; this allows for ease of use by multi-operators and also simplifies the maintenance and upgrade procedures for General Dynamics personnel.
