National Technical Systems
NTS has a number of facilities capable of conducting dual shaker testing, vibration testing utilizing multiple electrodynamic exciters, for the evaluation of large payloads.Once such example was conducted as part of the test program for NASA’s Lunar Atmosphere and Dust Environment Explorer or LADEE. NTS worked with NASA’s Ames Research Center for simulated environmental testing of the LADEE observatory which included dual shaker vibration.Vibration testing on the observatory was conducted utilizing the NTS Santa Clarita facilities tandem Ling B-340 electrodynamic exciters. These exciters allow either dual shaker vibration testing, or in the case of the LADEE observatory tests, they minimize the test set-up time. The electrodynamic exciters were staged with one in the thrust axis and the other set-up for lateral axes vibration. This dual shaker set up allowed for a quick transition from one test to the other. During the tests, the vibration test lab was maintained at a class 10,000 cleanliness level.

Crystal instruments
EDM Multi-Shaker Control (MSC) is a software option included in the EDM testing package along with VCS. Multiple Shaker Control provides one centralized interface to interact with multiple controllers running separate tests at the same time. Multi-shaker controllers are not time synchronized unlike in MIMO VCS, in which all drives are time synchronized.

KRD70 series -
CME Technology Co. Ltd.
KRD70 series hydraulic vibration shaker converts the energy of high-pressure liquid into the power of the reciprocating motion of the cylinder through the electro-hydraulic servo valve. Especially suitable for vibration tests requiring low frequency and high force. It can realize sine, random, multi-point excitation and shock test (sine, random, sine on random, random on random, or resonant search & dwell). It’s applied for reproducing the vibrations of transportation vehicles, bulk packaging products, machinery, electrical and electronic products in the actual environment, thereby optimizing the product structure and saving costs.

K-5201 -
ViTec Co. Ltd
n the course of vibration tests of finished products or prototypes, a number of steps are carried out that require certain, often very complex, algorithms for the operation of bench equipment and the processing of measurement results. Automation of the test process allows to reduce time costs, improve the accuracy of the task, the reliability of measurements, the visibility of information and minimize the impact of the human factor.

Unholtz-Dickie Corporation
By increasing the mounting area of the shaker, multiple items can be tested at the same time, decreasing total test cycle time. In addition, with Guided Head Expanders, payloads with large foot prints can be safely mounted and tested on the shaker, minimizing the risk of damage to the shaker suspension system. Although many head expanders are resonant below 1000 Hz, average or extremal control allows operation to 2000 Hz.

Crystal instruments
MESA tests are specifically required when the unit under test is too heavy or too big and exceeds the capabilities of a single shaker. In a MESA application, multiple shakers provide excitation to the test specimen in a single axis. Different relations like same magnitude and phase for drives, different phase for drives, different magnitude and phase for drives, can be set for this MESA test.
