| Abstract: | Using the method of sub-structure modal analysis and testing modal data, a dynamic model of a truck is built on computer which contains rigid-body modes and elastic modes up to 20Hz. In order to accomodate as many measuring points and modes as possible, a stepwise method is proposed. |
