Abstract
Chassis dynamometers are widely used in the automotive industry to evaluate vehicle performance. However, its usage brings some challenges, such as increased inertia of components, high costs and time. In this paper, we present a small-scale chassis dynamometer prototype design as an alternative to the ones used in the industry. The main goal of the present work is to describe the first outcomes of a project being carried in the Laboratory for Integrated Systems of Unicamp whose future objective is to further develop its chassis dynamometer for emulating standard/real driving resistances. It will be able to measure rotation and torque and allow us to obtain other parameters such as longitudinal speed, angular and linear accelerations, power and force. This way, it is possible to analyze the performance of a modular electric vehicle prototype. As a result, we present the design requirements, the 3D modeling of the system and its technical specifications of a small chassis dynamometer.
