Validate FEA results & prove product durability

By condensing a lifetime of stress and wear into a short period of time, noise and vibration testing can reveal hidden design weaknesses. Moreover, beyond merely withstanding short-term physical forces, developers need to ensure that their products will maintain the integrity and quality that represents the brand in the longer term.

Although product qualification and verification are done through extensive simulation in the development phases through simulation, it is also necessary to do physical testing on prototypes and end-of-line items. This both validates simulated results provided by vibration measurement and analysis to prove product durability to customers.

Modal Exciters

Core competences and comprehensive range of products and solutions to help customers solve vibration challenges. B&K offers the following Modal Exciters:

  • Type 4824

    A compact and lightweight modal exciter with a force rating of 100 N (22 lbf), Type 4824 is ideal for high-precision, single- or multi-point excitation of a range of payloads, from automotive powertrain and drivetrain components to large and very large structures.

  • Types 4825 and 4826

    With force ratings up to 200 N (45 lbf) for Type 4825 and 400 N (90 lbf) for Type 4826, these exciters are ideal where payloads require high-precision excitation in single- or multi-point setups. Strong and versatile, they are used for a variety of applications, such as testing of engines, body-in-white on passenger cars and small trucks, and aerospace structures.

  • Types 4827 and 4828

    Designed for the most demanding experimental modal testing applications, these exciters have force ratings up to 650 N (146 lbf) for Type 4827 and 1000 N (225 lbf) for Type 4828. They are ideal for high-precision, single- and multiple-point excitation of extra-large devices, such as locomotives, industrial turbines, heavy-duty pumps and aerospace assemblies.

  • Type 1056

    Designed to work as part of a system with our modal exciters and matching amplifiers, this unit enhances operation by correcting the position of the exciter’s armature or by applying pre-tensioning force to tension- or piano-wire stingers.

 
LDS Shakers

High-force Shakers, mostly used in the aerospace & defence industry

LDS Shakers

Brüel & Kjaer offers both air- and water-cooled LDS® shakers with a force rating of 80kN to 289kN for high performance vibration and shock testing.

The LDS® shakers have been designed to offer unmatched versatility and testing capability.  Combining high forces, large displacement, a wide frequency range, it is suitable for testing challenging or unbalanced payloads and small payloads alike for high-acceleration shock tests, as well as for testing with sinusoidal, random, and transient excitations.

Reliable and low-maintenance, it is comparably easier and more economical to install and operate; thus, offering maximum efficiency without compromising on quality.

B&K offer shakers for various environments:

 

 
Slip Tables

A cost-effective solution for most R&D and product verification applications

Slip Tables

A slip table offers a cost-effective solution for most R&D and product verification applications, including testing of military equipment, electronic assemblies, and aircraft and automotive components.

These low-pressure tables feature high-stability granite bases and slip plates manufactured from tool-grade magnesium, chosen for its high strength and light weight. They incorporate guidance bearings to minimize axial distortion and are capable of displacement up to 63 mm (2.48 in). A film of pressurized oil between the base and the plate gives uniform support across the entire surface and enhances payload support by decreasing table rippling.
