TIRA Vibration Test Systems Modal-Vibration Test Systems

Modal-Vibration Test Systems TIRA Vibration Test Systems Modal-Vibration Test Systems from 100 N to 2.7 kN These exciters are specifically designed for modal and structure analysis. Modal shakers up to 400 N are excited by permanent magnets, with lightweight rare-earth magnets provided for mobile use. These shakers are characterized by high cross-axial stiffness. From 1000 N onwards, modal systems permit a max. displacement of 45 mm due to TMC control. TMC is an electronic armature position control system for precisely coupling the modal shaker to the specimen. The armature datum adjustment...

Modal-Vibration Test Systems from 4 kN to 15 kN Especially for modal excitation of big structures or structures with high mass TIRA offers a range of modal systems from 4 kN up to 15 kN. These shakers are characterized by high cross axial stiffness and permit a max. displacement of up to 100 mm (pk-pk) due to TMC control. TMC is an electronic armature position control system for precisely coupling the modal shaker to the specimen. The armature datum level adjustment allows the operator to offset the nominal position of the armature in relation to the body. The axial stiffness can also be...

Special Modal-Vibration Test Systems TIRA Vibration Test Systems Special Modal-Vibration Test Systems 100 N to 400 N TIRA offers a new series of special modal systems for mobile use.The MOSP models distinguish themselves by an extended displacement of 25.4 mm. The low mass by using rare-earth magnets, the through-hole in the center of the armature for attaching tension-wire stingers besides push/pull stingers and for accomplishing a variable adjustment of the distance to the test structure, are additional features of this series. These shakers are characterized by a high cross axial...

Stinger - Push/Pull The stinger is also useful for isolating the moving armature from the test structure, reducing unwanted shock forces. Additionally it helps to avoid damages to the armature and the structure by unwanted excitations. TIRA offers a variety of stinger models, collet chucks and adapter for different types of application. Push/Pull Stinger Designation TR 35833 Description Push/Pull Stinger 2,5 x 200 mm (Adapter thread 10-32 UNF) Push/Pull Stinger 3,0 x 200 mm (Adapter thread 10-32 UNF) Push/Pull Stinger 2,0 x 500 mm with collet chuck M6 (Adapter thread 10-32 UNF) Push/Pull...
