Posted on December 6, 2011 Comments are off for this post

December 2011 – Twinsburg, Ohio – Mustang Advanced Engineering recently delivered an HSU test stand designed to simulate transmission input speeds and loads and vehicle output loads to the X1100-3B. The testing stand has the ability to control both the HSU’s input speed and output loads, allowing the operator to apply loads to the HSU as though it is in the vehicle. Cooling/Heating of the HSU will be accomplished with in tank heaters and thermostatically controlled oil to water heat exchangers located in the test tank and oil reservoir systems.

The HSU Test Stand will consist of 8 primary components:

• Input Drive Unit Assembly

• Power Absorption Unit Assembly

• HSU Container Assembly

• Test Stand Base Frame

• Oil Lubrication System

• Test Stand Tooling – Adapters, Fixtures and other hardware

• Roll Over Stand

• Test Stand Instrumentation

The X1100-3B HSU test stand power unit consists of a variable frequency AC motor drive and a variable speed AC electric motor prime mover. The test stand’s prime mover is an electric motor that is rated for multi-directional and reliable variable speed control. The prime mover is continuously rated at 1,455 HP with a base speed of 2,500 rpm and maximum speed of 3,990 rpm.

The test stand’s output PAU is a bi-directional water cooled eddy-current PAU. The PAU is capable of up to 4,000 lb-ft of dynamic load torque with a maximum speed of 3,330 rpm. The PAU has an infi nitely variable control range from no-load to full-load which is controlled via a manual controller on the control panel. The eddy-current power absorption unit is water cooled and will use less than 150 gpm of cooling water at 85°F.

“Mustang is proud to deliver this complex and extremely important test stand to Anniston Army Depot” said Dean Ganzhorn, Mustang President and CEO. “These HSUs are important to the success of the military and Mustang prides itself on delivering a quality and efficient test stand.”
