Method and system of comparison and analysis of suspension K&C testing stand test

Abstract

The invention discloses a method and system of comparison and analysis of a suspension K&C testing stand test. The method of comparison and analysis of a suspension K&C testing stand test is characterized in that by reading the K&C testing stand test data and the many-body dynamics model simulation data, and by means of an excel table, making a control file to control processing of data and the plotting pattern; reading the control file through software to realize flexible processing of data and generation of a report; strictly controlling the position of each work situation channel to be unvariable during the testing process of the K&C testing stand; supplementing increased channels later, and performing zero-fill processing on the channel which cannot output parameters; and through the software and the control file, realizing comparison of a plurality of K&C test data or comparison of a plurality of simulation data or comparison between the test data or the simulation data, and at the same time, outputting each work situation and the characteristic value of each performance parameter, and completing processing and analysis of test data and simulation data and writing of the report. The method and system of comparison and analysis of a suspension K&C testing stand test can improve the efficiency of processing and analysis of K&C data and writing of the report, can reduce the data processing problem caused by manual operation, and can improve the data analysis accuracy.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for comparison and analysis of a suspension K&C test bench. Background technique [0002] After the suspension K&C test bench test is completed, the test data needs to be processed, and at the same time, it is necessary to compare and analyze the K&C test data and the K&C simulation data of the multi-body dynamics model and write a report to verify the suspension performance parameters and the model modeling accuracy. Since a large amount of test data and performance parameters are involved, and a report is as long as 40 to 50 pages, these processes are all done manually, so there are the following problems: [0003] (1) Efficiency issues, such as: At present, it takes a lot of time and energy from the processing and analysis of test data and simulation data to the writing of the report. Generally, it takes four days to complete a complete K&C comparative...
