Abstract: The majority of vehicle dynamometer test rigs available in the market are constructed rigidly, which can test vehicles with a very narrow range of specifications, so there is a need for provision for load compensation to simulate the vehicle in order to test different vehicles & enhance the quality of measured results. The fabricated twin roller arrangement improves tire-roller contact and the provision for balancing system inertia with the inertia of the vehicle improves the accuracy of results during testing & makes the chassis dynamometer system a versatile test rig to test different vehicles and test parameters like speed, acceleration, brake force and brake distance, etc. A light weight and low base inertia fabricated twin roller arrangement is designed in the present study, and an inertia flywheel arrangement is connected to it for load compensation during acceleration, and an experiment is performed by loading an electric two-wheeler onto a two-roller setup to evaluate its performance. After testing an electric vehicle, the maximum speed and acceleration were determined to be 95 km/h and 3.65 m/s², respectively, and the brake force was 279.8 N with a braking distance of 7.48 m when applied from a speed of 20 km/h to zero. The obtained results were precise due to vehicle stability, provision for load compensation for vehicle simulation, and use of a mechanical inertia simulation using a flywheel in this test rig, which can be used to test different vehicles with a wide range of test specifications.
