Test method for realizing measurement items of real vehicle drum rack by using power assembly rack

Abstract

The invention discloses a test method for realizing measurement items of a real vehicle drum rack by using a power assembly rack. The method specifically comprises the following steps that S1, firstly, the whole vehicle is transferred to a power assembly rack through an external transfer device, and each wheel of the vehicle is arranged between two roll shafts on an independent rotatable platform.The method relates to the technical field of vehicle testing. The invention discloses a test method for realizing measurement items of a real vehicle drum rack by using a power assembly rack. The operating environment of the power assembly can be quickly and accurately controlled through the power assembly rack, perfect replacement is achieved, acceleration or deceleration and turning operation cannot be performed in the whole vehicle test of the drum test bench, in addition, in the driving process, the response speed, the vehicle body posture and the like of other vehicles to the tested vehicle can be rapidly simulated, the state of the simulated vehicle in the road form is improved, and more excellent test services are provided for development of vehicles and automatic driving vehiclesin cooperation with a corresponding software operation system.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a test method for realizing measurement items of a real vehicle drum bench by using a power assembly bench. Background technique [0002] With the development of society, people have higher and higher requirements for automobiles, and the replacement technology of automobiles has never stopped. In the process of automobile research and development, the drum test bench is a very important indoor bench test equipment. Through The drum test bench can not only test the power of the car, but also measure the emission indicators and fuel consumption of multiple working conditions, which provides a certain test basis for the study of the power, economy, comfort and handling stability of the car. , has played an important role in accelerating the development of the automobile industry, shortening the product development cycle, saving product development costs, and improving th...
