A. multi-purpose vehicle chassis dynamometer
With the rapid development of the automotive industry, traffic accidents and environmental pollution on the growing threat to human life, thus increasing the importance of vehicle detection technology stand out a variety of testing equipment have emerged. As a large-scale laboratory equipment, automobile chassis dynamometer can simulate vehicle road test a variety of conditions, pletion of the car's economy test, power test, evaluation and analysis of emissions performance, reliability test and drive the car on the special test . It is in the automotive testing research, product development and quality testing new cars and the car is essential. plete chassis dynamometer test and the type of vehicle quality inspection and road pared with the usual test speed, high precision, low cost, data stability, comparability and good.
In view of chassis dynamometers these advantages, many domestic manufacturers have developed a series of dynamometer products, these products are mainly used to detect the following auto axle load 10 t chassis power output, the maximum absorption power of 150 kW. Test items mainly: chassis power output, the driving force, speed, acceleration, glide performance and the accuracy of the speedometer and odometer, and so on.
But domestic dynamometer products there are many imperfections, must be resolved. F
