MD-1100 Chassis DynamometerMaintenance & Service Manual1.1What is a Chassis DynamometerToday and in the future, automobiles and trucks will be required to meet increasinglystringent emissions and safety standards. In many cases, dynamic testing - either onhighway or with a chassis dynamometer - is the only way to adequately measure vehicleperformance or emissions.A Mustang Chassis Dynamometer (sometimes referred to as a "Dyne" or "Dyno") is arugged piece of equipment which is used to apply a load to a test vehicle. The Mustang Chassis Dyne is an integrated assembly of mechanical, electro-mechanical, andelectrical/electronic sub-systems which function together to provide you with the ability to simulate actual road loads while the vehicle being tested remains in the safe andcontrolled confines of a test center. In addition to the vehicle performance informationprovided by the Dynamometer System during a test, this capability will also enable you toconnect test instruments and diagnostic equipment to the test vehicle's engine to monitorspecific engine performance characteristics.As the torque from the test vehicle's drive wheels causes the rolls of the Dyne to rotate,Mustang's air-cooled electrical eddy current Power Absorbing Units (PAU) opposes thisforce by converting the vehicle's kinetic energy into heat. A microcomputer-based controlunit, using closed-loop feedback control, regulates the amount of power that is absorbedby the PAUs and, as a result, the amount of load that is imposed on the test vehicle.The Chassis Dynamometer has emerged as a major asset in the areas of EmissionsTesting, Fault Diagnosis, Performance Engineering, and Test Engineering throughout theworld. Chassis Dynamometers can be used to perform a wide variety of tests on cars,trucks, and tractors; some examples of these tests deal with Vehicle Heating & Cooling Systems Engine Performance Drive Train Component Evaluation Transmission Components Tire Testing Road / Track Simulation % Grade Simulation Trailer Towing Simulation Fuel Efficiency Auxiliary Components Failure AnalysisIntroduction1-2

MD-1100 Chassis DynamometerMaintenance & Service Manual2.3Principles of OperationThe Mustang Chassis Dynamometer will give you the ability to simulate actualroad loads while the vehicle is stationery. This enables you to perform tests ona vehicle while test diagnostic instruments are connected to the vehicle's engineand exhaust system.The Dynamometer consists primarily of drive roll set, a power absorbing unit(PAU), a load cell, and a speed encoder.During operation of the Dyne, the vehicle's drive wheels on top of the rolls.The vehicle's torque is transmitted through the rolls to the eddy-current PowerAbsorbing Units (PAUs). The PAUs are prevented from "freely" rotating bythe installation of a load cell. The "load" is measured by the load cell and istransmitted to the control system via an electrical signal. The PAU absorbs thisload by energizing stationary electric field coils with a direct current. These coilsestablish magnetic fields through which the iron rotors of the PAU are rotated.This rotation generates eddy-currents in the rotors which produce a force thatis counter to the direction of the rotary motion. The power absorbed by the PAUis dependent upon the amount of DC power applied to the field coils and theRPM of the spinning rotors. The speed of rotation of the rotors is measured by amagnetic device called a mag pickup and is transmitted to the control system.When both torque (from the load cell signal) and speed (from the mag pickupsignal) are known, horsepower can easily be determined.2-6The System

MD-1100 Chassis DynamometerMaintenance & Service Manual4.3.5 CHAIN ANCHORSIt is common for vehicles to move laterally on the rollers during dynamometer operation.To prevent personal injury and damage to the vehicle it is imperative that the vehicle besecured with chains. The dynamometer is supplied with 4 chain anchors that must bepermanently installed as illustrated in the Appendix.4.3.6 CLEARANCEIt is important to have enough room around the dynamometer to allow equipment to bemoved around the service bay area. At least 20 feet clearance is needed in front of thedynamometer so that the vehicle under test has enough room to pull in the service bay.There are two ways to install a Mustang Chassis Dynamometer, above ground or belowground. The following section describes both methods.Installation of your new MD-1100Tools and Equipment Needed for Installation Standard Hand ToolsHammer drill5/8 “ masonry drill bitShim stockShop air for cleaning debris from the holesChains with hooks (2) 18ft.Forklift, minimum of 5 ton capacity, or 10,000 lbsBubble levelIn this section we’ll go thru step-by-step of both above ground, and below ground installations. Thefirst few steps apply to both types of installation.Remove the dyne’s cover plates, do this by using a 5/16 Allen wrench to remove the button head bolts,first remove the 3 access plates located in the center, between the 2 rolls.Remove the dyne’s roll cover plates. BE CAREFULL! These plates are very heavy and awkward tobalance.Remove the “grating” above the PAU.Remove the lag bolts that hold the 4 X 4 wood pieces to the feet of the dyne.Installation4-4

MD-1100 Chassis DynamometerMaintenance & Service ManualNOT FOR CONSTRUCTIONBELOW GROUND INSTALLATIONCheck dynamometer pit and verify dimensions. Also, make sure the conduits are in the proper locations.Clear the pit of all debris.Using the two chains, as shown in Fig. 4.2 Lift the dynamometer evenly, and place in the pit. There should be approximately 1 2”clearance between the frame and all walls of the pit.MAKE SURE THE CHAINS ARE SECURE, if the chains slip when lifting, serious injury can occur. Do not allow the dynamometer to hit the ground or the pit walls. The bearings are very rugged and can easily withstand normal dyne operations, but theywill be damaged if there is a sudden impact.
