When the actual vibration test is carried out, the specimen or fixture will often be larger than the moving platform table, so the original mesa will need to expand. The common method is to install an auxiliary table. In the working frequency, table weight, mesa acceleration, amplitude uniformity and lateral movement, there are strict requirements for the extended table.

The company can make a square or circular expansion platform based on the special requirements of the customer

Vertical expansion platform specification

Explain：

A, for example, JDZ630: "JDZ" refers to a vertical square platform, and "RT" refers to a circular platform;

B, table standard stub layout:

JDZ630~ JDZ650 uses a 80 x 80mm rectangle cloth hole;

The JDZ660 ~ JDZ715 uses a 100 x 100mm rectangular hole.

C, equivalent mass and frequency range all represent the aluminum vertical platform. The equivalent mass of magnesium platform is reduced to 65% of the same type aluminum platform, and the frequency range of use is reduced to 90% of the same type aluminum platform.
