IMPLEMENTATION OF A THIRD GENERATION SOUND POWER TEST FOR PRODUCTION TESTING OF EARTHMOVING EQUIPMENT.
In 1988, Caterpillar, Inc. developed an automated sound power measurement system to measure construction equipment sound levels prior to their shipment from various assembly plants. This system was primarily developed to address stationary or static sound power regulations prevalent in Europe. However, this system is not capable of verifying compliance to new dynamic sound power requirements effective January, 1997. To address the more complex dynamic procedures, Caterpillar has developed a new automated test system capable of measuring static and dynamic sound power. The automation level of this system is such that tests can now be conducted in a matter of minutes by one person, thereby eliminating the lengthy 1-2 hours of set up time and the need for additional support personnel. This paper will describe the new Caterpillar System and its implementation at our worldwide facilities.
