<b>Abstract :</b><p align="justify">One of the ways to fmd out vehicle's dynamic characteristic is by tested on laboratory scale. This test's aim is to get data of vehicle's operation load between its wheel and surface of pathway on vertical force. <br /> <p align="justify">By using two sensor, accelerometer and displacement transducer, we'll see amplitude's length for each test's data on frequency domain (0-40 Hz) and three data input which represent fine pathway (DFBBTl ), medium (DFBBT2) and bad (DFNLT1), which are data vehicle operation load. <br /> <p align="justify">Data from displacement transducer will be differentiated twice and the compared with data from accelerometer sensor to get transfer function between vehicle's wheel and the surface of pathway. Transfer function presented on time and frequency domain. From transfer function analysis on frequency domain to three measurement input data, we get a relatively similar amplitude pattern where minimum amplitude lies between 11-15 Hz and maximum amplitude lies between 35-39 Hz. <br /> <p align="justify">From validation model for transfer function analysis in time domain, we get very low mean square error value between measurement output and estimation output for each measurement data. So we can conclude that transfer function characteristic from each measurement data is relatively similar
