Open servo vibration dynamometer system and method for realizing vehicle dynamics or road test

Abstract

The invention relates to an open type servo vibration work measurement system which comprises a work measurement subsystem, a servo vibration subsystem and a control subsystem. The work measurement subsystem is used for measuring power states of an object to be measured and comprises a first connection portion, the servo vibration subsystem is used for achieving mechanical vibration and comprises a second connection portion which is fixedly connected with the first connection portion when a simulation vibration environment is needed providing for the object to be measured, and the control subsystem is used for controlling the work measurement subsystem and the servo vibration subsystem to move. The invention further relates to a method for using the open type servo vibration work measurement system to achieve the vehicle power or the road tests. By means of the system and the method, purposes of synchronously inspecting various tests, reducing equipment investment, reducing manpower resources, shortening test period, lowering testing expenses, expanding the tests and the like are achieved, and various problems in the prior art can be effectively solved.

Description

【Technical field】 [0001] The invention belongs to the technical field of vehicle testing, and in particular relates to an open servo vibration dynamometer system and a method for implementing a vehicle dynamic test or a vehicle road test using the same. 【Background technique】 [0002] The power test of the powertrain system or transmission system on the vehicle, the road test of the whole vehicle, and the reliability test of the normal temperature road are all indispensable and important links in the process of vehicle development and design. However, these tests in the prior art are all There are some deficiencies or technical bottlenecks. [0003] For example, the vehicle dynamic test method is traditionally single, and a variety of equipment is required to complete the corresponding test, which usually requires a lot of test work in the vehicle development stage, and it is inevitable to invest in a lot of test equipment; equipment investment is large but utilization Low ...

AI Technical Summary

Problems solved by technology

Since the road reliability test takes a long time for the actual sports car, it will inevitably lead to high test costs such as site investment (or rental), labor, and work costs, which will become a considerable expense in the development of new models

It is particularly important that the road reliability test may become a serious factor restricting the launch cycle of new models, which will directly affect the economic benefits of automobile manufacturers and dealers, and cannot meet the needs of consumers in a timely manner

[0005] In the Chinese patent literature with the publication number CN101498615A, an electric road simulation vibration table is disclosed, although it can simulate road vibration by using motor drivers, servo motors, couplings, actuators, data acquisition devices, and computers. test, but this invention still cannot solve the above-mentioned problems
