Electrodynamic 3-axis Vibration Tester
Our unique technology, "special slide mechanism" and "floating mechanism" enable 3-axis simultaneous vibration test in high frequency band up to 2000 Hz, which was difficult to realize so far. A frequency range up to 2000 Hz is essential for vibration testing Of Aerospace Electronic And Electrical Devices. Conventional Single-Axis Vibration Testing Has Been The Mainstream In Conventional High-Frequency Vibration Testing Machines, But High-Frequency Three-Axis Vibration Testing Is Essential To Ensure High Reliability Of Electronic Components Such As EVs, HEVs, motors, inverters, ECUs and PCUs. By performing a 3-axis simultaneous vibration test, it has become possible to reproduce complex vibration generated in a real environment in the test room.You can also select various environmental tanks. It is possible to select a high performance model with low cross talk and high surface distribution performance and a general model .

Site Vibration And Noise Testing
Response Dynamics Vibration Engineering, Inc.
Effective vibration isolation is critical to the performance of many systems. It is often much more challenging than expected because the structural dynamics of the supporting structure, and the isolated structure, also affect the isolation performance. Isolation resonances can often create other vibration problems and confound an engineering team. We have successfully designed vibration isolation into countless systems over the years using unique custom solutions as well as adapting standard components and applying them properly to the design.
