Vertical Extension Platform︱The extension platform is usually used as a platform for larger mounting specimens, which can be square or round or user-defined. In order to reduce the influence of dynamic characteristics of the expansion platforms, all the expansion platforms must be modeled and analyzed for their modal frequencies. These expansion platforms are generally made of magnesium alloy casting and attached with damping materials.

● Powerful Functionality and Flexibility
Electrodynamic shaker system’s controller a powerful vibration control platform, can complete a number of complex tasks. On the same hardware platform, different applications can be configured to complete a variety of analysis tasks to meet your different test analysis needs. The vibration shaker controller adopts modular design, which can configure the corresponding hardware and software according to the different needs of users to meet the different needs of users.
● Test Safety︱Electrodynamic Shaker
Electrodynamic shaker system’s controller can provide small magnitude signal control to get a preview of system vibration control. This method can help test engineers determine the noise level in advance and understand the transfer function and other characteristics of the system roughly, There are also a number of security checks and interlock Settings to ensure maximum safety of testers, test objects and electrodynamic vibration system. If the shaker vibration system is abnormal, you can immediately press the built-in termination key to end the test.
● The Test Report Generate Very Easy
Support one-click quick generation of word format or PDF format test report function, You only need to click the report generation button to get the current trial results. From the basic test control function description to the specific test setting parameters, from the control target spectrum curve to the test time and frequency domain curve. Horizontal table and shaker is convenient for you to modify and make according to different test report specifications. It can print directly and print preview, and it can be sent online.
