The Structural Design Of All-wheel Drive Vehicle Chassis Dynamometer
Abstract
The Chassis Dynamometer is an important indoor bench testing equipment, through the chassis dynamometer,it can not only have a testing for the power of the car, but also can measure the status of multi-emissions and fuel consumption indicators, at the same time it can easily debug and diagnosis of motor vehicles loaded car under load fault conditions, such as. All test results are determined by the accuracy and reliability of the chassis dynamometer can of road vehicles to make a real simulation of the resistance.
This article from the chassis dynamometer to start an overview of several basic devices, combined with its development of its working principle and analysis of mechanical structure, completed the design. Mainly in the design of the drive motor, drum, air-cooled devices, such as sensors, as well as a selection of models and sizes and to determine the size of the installation to complete the structural design.
In this paper, the use of the exchange of dynamometers to replace the traditional eddy current dynamometer and hydraulic dynamometer, through advanced technology for the control of AC dynamometer to reproduce the situation of road vehicles. Not only the inertia of the flywheel eliminate red tape and simplify the mechanica structure, and can be achieved without the level of inertia simulation.
