THE DESIGN OF THE DYNAMIC SIMULATION
BENCH FOR TRACTOR HYDRAULIC
MECHANICAL TRANSMISSION
ABSTRACT
With the rapid development of motorcar industries, the performance of
gearbox is ing more and more important. In order to shorten the
development period of automatic transmissions of motorcar and reduce the
research cost, this paper regards the HMT dynamic system of 1302R of Henan
University of Science and Technology as the research background, and carried on
a research about the test item and the method, then developed a test system for
the performance of HMT. This article consists of ponents below:
First, we introduce the system’s structure in general: the tester’s energy is
provided by the direct current motive, making use of the quickly install
equipment of fixed the position of HMT; choosing the NJ type’s torque
equipment to test the torque, choosing the direct current generator as an add
device, then design a gearbox according to the output power of the HMT.
Second, using the PCM3132 detecting the system’s oil pressure, controlling
oil pressure, cooling flow or discharge etc, all these above parameters will
contribute to diagnose the HMT. These signals can be output to the screen and
displayed through an A/D change.
This paper introduces ponents and working principle of the
DC-power closed mechanical drive tester, on t
