It's analyzed that the dynamic feature of frame-type foundation (high rotational speed and changeable rotational speed), spring-type foundation, biock foundation and the equipment foundation on the floor are basis on testing results and theory caiculations. Some new suggestions are also given on the rotational equipment foundation design and calculation method. SVMA module analysis system on PG computer is introduced. The testing data of this paper are analyzed with this system.
