Design and Implementation of a Chassis Dynamometer for Testing Battery-Powered Motorcycles

Abstract:- The objective of this paper is to design and implement a chassis dynamometer for testing dynamic characteristics of a battery-powered motorcycle (BPM). By using a load simulation system, which is constituted with a DC motor and two rollers, a roller of the test platform is connected to a DC motor through a torque sensor, and a controller is designed to control the DC motor to simulate driving resistance produced when the BPM runs on various roads. The test platform can simulate each drag force when the BPM is in acceleration or in a constant-speed drive, and also can simulate kinetic energy gained by the BPM when braking, deceleration and running downhill. A computer not only controls the test platform but also collects signals from sensors on the test platform and the BPM, and can analyze related data such as driving resistance, driving range, speed, kinetic energy recycle and so on. The test platform has an integral steel structure and a stable center of gravity, and the height and length adjustment of the machine is convenient and as well the test is easy to perform, thus it can provide efficient tests on battery-powered motorcycles (BPMs) which are currently popularized by all circles with great efforts, so as to achieve the objective of performance measurement, performance analysis and data collection. From experiment results, the BPM performance test platform can simulate various road patterns and complete an automatic testing process
