Abstract:

The aim of this paper is to propose a new method for designing a six-component WFT employing wireless data transmission and thus constructing a smart data acquisition and analysis system for roadway test.It was able to measure real-time
six-direction wheel loads and other important parameters when the vehicle was running, and provided the experimentalist with friendly graphical users’interface, so that the evaluation and diagnosis of vehicle performance under different road conditions can be achieved.The mechanical design of the six-component WFT and the complete system,revalent data processing and actual experiments were discussed in detail.Experimental results indicate that the whole system is effective and ideal.

Key words: six-component wheel force transducer（WFT）;vehicle roadway test, elastomer;wireless data tansmission;demarcating;decoupling
