Study on designing and manufacturing fluid chassis dynamometer for motorcylce

Abstract

    This paper presents study results on manufacturing motorcycle chassis dynamometer for research and education. The motorcycle chassis dynamometer was designed including a water brake, transmission system, water supply system, cooling system, force sensor and speed sensor. The transmission system is used a main roller which is received torque and power by wheel. The main roller and rotor of water brake are combined by a transmission shaft, a second roller is used to guide the wheel. Water supply system which has two centrifugal water pumps is a closed circulation system. The first water pump is used to bring water from the tank to the brake, the other transfer water through radiator to keep water temprature stably. Brake force is controlled by varying the level of water recirculating within the brake with adjustable inlet and/or outlet valves and orifices. The chassis dynamometer uses loadcell and encoder to measure force and speed. The sensor signals are transmitted to the hardware that communicates with the computer. The signals are calculated by the graphical programming language of the labview software to display the torque, power and speed parameters in the computer interface.
