“…The automobile industry has played an indispensable role in the development of the national economy, and has long been the focus of national investment.In China's automobile industry economy, commercial vehicles have always been a part of great contribution, and commercial vehicle drivers work intensively for a long time.The corresponding demand for comfort is also stronger [1]. Consumers' demand for commercial vehicle products has gradually changed from practicality to personalization.The requirements for ride comfort are getting higher and higher [2].…”

In the process of research and development of automotive products, the man-machine layout design of cab comfort has become the focus of development. At present, to judge whet that man-machine arrangement of the cab of the commercial vehicle meets the comfort requirement, a sample vehicle is usually manufacture first, Evaluated by professionals, this development process is not only cumbersome, high error rate and low efficiency, but also consumes huge human and financial resources. In this paper, the man-machine bench test of commercial vehicle is designed and carried out. The corresponding comfort evaluation data of each percentile driver under different man-machine arrangements are collected.Secondly, a RBF neural network model is built to predict the subjective evaluation of man-machine layout. The training set and test set of the model use the data from the bench test, and the accuracy of the model is evaluated by objective indicators. Finally, the secondary development of the commonly used design software CATIA is carried out, and the program is written to automatically read the size information of the three-dimensional model. One key evaluation is realized by embedding RBF neural network. The example shows that the software of RBF neural network and CATIA secondary development can greatly improve the efficiency of designers.

This paper introduces a method to quickly and accurately identify the sound quality of automatic transmission in a vehicle by testing the objective vibration parameters on automatic transmission EOL (end of line) test bench. In this study, 50 automatic transmissions serve as the research object, and the vibration parameters of each gear of the transmission are measured on the EOL bench. Then, the transmission is mounted on a vehicle, the vibration parameters and acoustic parameters of corresponding working conditions are measured, and the subjective evaluation of the noise quality of the vehicle is carried out by using a grade scoring method. After this data is collected, the specific vibration parameters and acoustic parameters that are the dominant factors of sound quality are determined by correlation analysis. Based on the multiple linear regression method, the following mathematical models are formulated: the vibration parameters and the subjective evaluation of a vehicle, and the acoustic parameters and the subjective evaluation of a vehicle. Among these models, the mathematical models of the vibration parameters and the subjective evaluation of a vehicle were verified to be more accurate. The consistency between the vibration value in a vehicle and the vibration value on EOL test bench is analyzed and the EOL vibration value is determined to be the most objective evaluation of the data. After batch testing of 100 sets, the effectiveness of this model is within 95%. Finally, the value of critical amplitude of the condition of each gear of transmission is analyzed to form the judgment standard of transmission EOL vibration to ensure better sound quality for the vehicle.
