System Features |
|
The Model 3100 is an SAE No. 2 Type Wet Friction inertia dynamometer designed to perform standard SAE and developmental wet friction testing on clutch and band systems. This machine incorporates the latest controls and software technology for optimal testing versatility and correlation to actual powertrain operating conditions.
The system is designed with a variable speed AC main drive motor, providing the capability for inertia simulation (I-SIM). This feature supports continuous slip testing, improved torque control, and an unlimited range of inertia. The secondary drive is a high torque, bi-directional AC motor coupled to the main drive motor, providing low speed continuous slip and static breakaway friction testing capability.
Torque is measured via dual load cells mounted on dual torque arms on the test head. The test head is mounted on dual back-to-back precision angular bearings attached to the machine base for reduced vibration at high speed operation. Test head piston apply force is generated by pneumatic pressure or an optional hydraulic system. Test fluid is supplied to the test head with a recirculating hydraulic system, while fluid temperature is controlled with a system of in-line and tank heaters.
