Examples of this type of testing include a universal hydraulic pump test stand which uses a 200 Hp variable speed drive, computerized data acquisition and control system, and specialized sensors that can measure in-line fluid density, mass flow, and drive torque. An example of our tractor testing capability is our tractor axle dynamometer. This dynamometer was designed for testing agricultural or industrial tractors under controlled conditions. The dynamometer easily adjusts to accommodate different makes and models of tractors. The torque is controlled independently for each wheel by a microprocessor-based process controller.
Data acquisition is also available.
This equipment has been used successfully to perform drive train endurance and clutch life tests. Specialized test stands have been developed in order to support development and product qualification testing of on and off-highway equipment. Typical test set-ups are designed to evaluate transmissions, hydraulic system, clutches, and final drives. Depending on the complexity and scope of the project, test stands can be completed in weeks or even days. SwRI technicians also diagnose and repair the items under test, if the client so desires.
