air-cooled electrodynamic shaker
Bruel and Kjaer
An air-cooled electrodynamic shaker with a high overturning moment and a force rating of 80 kN (17,894 lbf), for high-performance vibration and shock testing of large devices. Ideal for the aerospace & defence and automotive industries.
The LDS® V8900 high-force shaker has been designed to offer unmatched versatility and testing capability. Combining high forces, large displacement, a wide frequency range and up to 3 kN·m (2212 lb·ft) of overturning moment, it is suitable for testing challenging or unbalanced payloads and small payloads alike. It is suitable for high-acceleration shock tests, as well as for testing with sinusoidal, random, and transient excitations.
Three-axis testing of complete satellite systems
Testing at very low vibration levels for payload characterization
Low-frequency, large-displacement testing for large payloads
Durability testing of avionics and military hardware
Squeak and Rattle testing for the automotive sectors
Extended vibration testing
Capable of supporting payloads up to 800 kg (1763 lb) and delivering sine forces up to 80 kN (17,894 lbf), V8900 has the power of a water-cooled shaker with all the benefits of air-cooling. Reliable and low-maintenance, it is comparably easier and more economical to install and operate; thus, offering maximum efficiency without compromising on quality.
For enhanced shock and low-frequency testing, V8900 features a long stroke, with a maximum displacement of 101.6 mm (4 in). A frequency range from 5 to 3000 Hz makes it suitable for long-duration vibration tests, as well as for tests involving smaller articles.
