| Abstract: | Taking a chassis dynamometer test system as an object of study,a real-time simulation and control system was set up.After analyzing driving resistance on the road,a model of automobile driving resistance was established.By means of the programming tools in Labview 8.5,a dynamometer data acquisition system was developed on the master computer.By transferring the resistance calculation model from the master computer,the torques on the drum of dynamometer can be controlled in real time,and thereby the simulation of automobile driving resistance on the road was realized.The results of error analysis showed that the system was of higher simulation accuracy. |
