Ed Shakers Tips Vibration Test Table For Automobtive And Transportation

Vibration test system is ideal for the aerospace & defence and automotive industries. The shaker combines high forces, large displacement, a wide frequency range and up to 3 kN·m (2212 lb·ft) of overturning momentm making it suitable for vibration testing challenging, or unbalanced payloads and small payloads alike. Vibration table is suitable for high-acceleration shock tests, as well as for testing with sinusoidal, random, and transient excitations.

• Extended vibration testing

Capable of supporting payloads up to 500 kg (1063 lb) and delivering sine forces up to 49kN (10,894 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 51 mm (2 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.

Its cutting-edge design enables the shaker to perform at its full potential, even when testing payloads with offset centres of gravity. The incorporation of hydrostatic bearing technology gives the shaker its rigidity, enabling high overturning moments of up to 3 kN·m (2212 lb·ft), increasing stability for large or complex payloads without the need for guided head expanders. This also reduces maintenance needs and minimizes costly downtime, as there are no worn-out rollers nor flexures to replace.

The armature’s electrical, non-optical and non-contact centring system affords accurate armature guidance with minimal maintenance and uninterrupted operation, since neither dust nor temperature fluctuations in the environment affect accuracy.

Air-cooling eliminates the need to power and maintain a water-cooling plant, resulting in lower running costs for the V8900 system. The shaker also features an easy-to-operate and intuitive UI design, with straightforward operating functions and usage feedback data.

Vibration tests verify product requirements and assess robustness for transport or use conditions. These five expert tips will help optimize your vibration testing process.

2. Consider the fixture carefully

Mount test objects as they would be in normal use. Fixtures should create stable connections without adding resonances. IEC 60068-2-47 provides excellent guidance on fixture design.
