Firstly, the 3D solid model of the analyzed object is built directly in the FEM software ANSYS 8.0 without using other CAD software. The influence of the side sizes of solid elements on computing results and the influence of coupling ways between different parts on the modal parameters are researched by simply modeling. And a new connecting method about joints in ANSYS is proposed and applied to finite element modeling of the test-bed for spindle system. Furthermore, several different computing techniques for modal parameters extraction are compared in solving the finite element model of spindle system test-bed. Many modal solutions are also done to achieve the relationships between the whole or part stiffness value and computed modal parameters. The laws about joint rigid parameters" influences on modal parameters are discussed by means of altering their values for conjoint parts. And by changing local rigid parameter values, the different location selections" influence on computed modal parameters is also studied.

One end is the substantial use of the third person form, the present tense and the past tense; through frequent use of the third person form as the Subject, the writers of commercial editorials are at a position of an impartial third party describing the facts in an apparently neutral manner; the past tense and the present tense are also considerably employed to further help to enhance the objectivity of the writers" presentation, for they reflect the facts and events which did take place and do stay there now. The other is the moderate employment of modal operators and Modal Adjuncts. Those of low value group and median value group form the main body of all the modal operators; instead modal operators of high value group occur least frequently, which imply writers" strong attitude.
