GT4000—Vehicle Transmission Test System—Main Features
01 Functional principle
All benches are constructed using functional calibration, and are combined in a test system in the form of a combination of modules. Customers can add or remove test modules according to different test objects.
02Advanced measurement methods
Adopt advanced real-time measurement and control system, including input electrical parameter test, calibration sampling test, etc. The sampling rate is up to 1000Hz, which meets the requirements of high precision and fast response of the test system, and provides transient data and characteristic value data to facilitate the software follow-up test process The data is fully analyzed.
03Complete test items
According to the test requirements specified in the national standard, test items can be added or removed according to the configuration module, which can meet the test items for various types of tests
04shift mechanism
The advanced servo mechanism is used to complete the shift test of the manual gearbox shift logic.
05Drive system
Using low-inertia asynchronous motor/permanent magnet synchronous motor as the system drive input, improves the system's scale and steering dynamic response characteristics, provides measurement range and accuracy, improves drive performance (forward/reverse), and response time for continuous loading , It can realize the loading of any load curve and highly simulate the real-time operating conditions of the electric drive assembly.
06 loading system
The atmospheric pressure low-speed dynamometer is used as the system loading, and the high-precision variable speed is adopted according to the characteristics of the test piece. The serial sensor improves the data dynamic response rate. The system loading adopts the vector/DTC mode to achieve the required high-speed dynamic loading characteristics. , Thereby highly simulating the real-time operating conditions output by the gearbox.
07Humanized design
Using a professional gearbox test bench, the fixture has a quick clamping function, and is convenient for loading and unloading. It can be adapted to different gearbox installations. The system operation is recommended to adopt the cabinet + computer desk control mode, which can complete the layout of all test operations in a single position.
08Customized testing software
The test system test software developed by the Sichuan Chengbang Software R&D team, in accordance with the national standard requirements test items, classifies the software interface and process, reduces repeated tests, and greatly improves the work efficiency of testers. And at the same time real-time curve drawing, transient value capture, trend curve estimation and analysis, multi-parameter combination display, qualification judgment, report export and other functions.
