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 to test different vehicles & enhance the quality of measured results. The fabricated twin-roller arrangement enhances tire-roller contact, and the provision for balancing system inertia with the vehicle’s inertia improves the accuracy of results during testing. This makes the chassis dynamometer system a versatile test rig for testing various vehicles and parameters, including speed, acceleration, brake force, and brake distance. A lightweight and low-base-inertia fabricated twin-roller arrangement is designed in the present study. An inertia flywheel arrangement is connected to it for load compensation during acceleration. 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 the vehicle’s stability, provision for load compensation in the vehicle simulation, and the use of a mechanical inertia simulation with a flywheel in this test rig. This test rig can be used to test different vehicles with a wide range of test specifications.
