This report presents an analysis of hydrostatic drives applicable as propelling units for Automated Guideway Transit (AGT) small vehicles. The study includes a comprehensive state-of-the-art survey of hydrostatic drive units and the development, design, and performance requirements for a 15 HP hydrostatic drive propulsion system for an AGT system. The study included a series of testing on a 15 HP unitized hydrostatic unit to evaluate performance characteristics and acoustic noise. Acoustic noise of hydraulic equipment, especially the hydrostatic drive, has been studied and the findings reported herein. A series of tests were performend on the unitized 15 HP hydrostatic drive to simulate an AGT small vehicle duty cycle using a 20 and 29 GPM hydraulic motor. These tests were conducted on a eddy-current clutch dynometer, 35 HP capacity and utilized specially designed and developed processor to produce the simulated duty cycle during the tests. In addition, noise level tests were performed on the unitized hydrostatic drive with the 20 and 29 GPM hydrostatic motor and applied with and without shield constructed as a box to dampen hydrostatic drive noise.
