4. Three-axis six-drum chassis dynamometer
Vehicle power performance is the main index to evaluate the performance and technical status of the vehicle. With the continuous improvement of road conditions, especially the rapid growth of expressways, more requirements are put forward for the power of automobiles. At present, there are limits on the lowest speed of automobiles on expressways, and cars with poor power are not allowed to go on expressways. The rapid development of fast and direct passenger and freight transport also puts forward higher requirements for the power performance of automobiles. Therefore, the detection and evaluation of automotive dynamic performance has become one of the important test items in the comprehensive performance testing of automobiles. The evaluation indexes of automobile dynamic performance are: maximum speed, acceleration time and maximum gradient.
Chassis dynamometer is a kind of indoor test equipment, which can simulate the resistance of the vehicle in actual driving, test the performance of the vehicle and test the technical status of the vehicle. As an indoor vehicle dynamic bench test, chassis dynamometer is mainly used to test the output power and acceleration ability of the chassis.
