“…The latency corresponds to a single step for the desired motion and is calculated by dividing the number of steps required for a period of harmonic motion using this obtained delay. Where f d represents the desired (demand) frequency, f a is the achieved (response) frequency, and A represents the amplitude of the harmonic motion, and ltc f represents the calculated latency per step [13].…”

“…Najafi and Spencer Jr. [12] developed the modified model-based controllers' method in their studies, and with this method, they investigated the accuracy of a single-axis Quanser shake table and determined the error rates with different methods and compared the methods. Damcı and Şekerci [13] developed a single axis, 500x500 mm 2 shake table controlled by Arduino microcontroller platforms and driven by a stepper motor. The control algorithm, calibration method, and performance investigation of the shake table were given in detail.…”

“…In this study, an application of the calibration method given by Damcı and Şekerci [13] is introduced for the new bi-axial shake table SARSAR (Figure 1), which is placed in Structures and Mechanics Laboratory at Istanbul University-Cerrahpasa in Buyukcekmece campus, is presented. There are considerable differences compared to the previous study [13]. This study is a further application of the method for a larger bi-axial shake table with higher payloads up to 600 kg.…”

Shaking tables are frequently used to determine the dynamic behavior of structures in the laboratory environment. In order to obtain realistic results in experimental studies, table response and performance should be consistent with the desired motion. In this multidisciplinary study, an application of a new method for determining and calibrating the mechanical response of a developed bi-axial displacement controlled shake table according to the desired motion data is presented. The bi-axial shake table's electro-mechanical components consist of stepper motors, ball screw sets, linear ball bearings, and linear potentiometers positioned on both axes for displacement measurements. For the control and data acquisition (DAQ) unit of the shake table, an open-source electronic prototyping platform Arduino was used. From several experimental results, it was seen that, with the presented calibration method, harmonic and earthquake simulations could be achieved with a relative root mean square error (relative RMS error) of less than 5% for desired displacement-time histories.

“…Some applications can be found in which these low-cost systems have been applied to high-frequency dynamic systems. For example, in [8], a low cost acquisition system was developed for a single axis vibration shaker table for civil engineering applications. In this case, the shaker table was used to simulate horizontal acceleration data recorded during earthquakes and was based on an Arduino DUE for control of the table and an Arduino MEGA for the verification of the acceleration obtained.…”

This article presents a novel and reliable low-cost data acquisition solution for high frequency and real-time applications in vehicular dynamics. Data acquisition systems for highly dynamic systems based on low-cost platforms face different challenges such as a constrained data retrieval rate. Basic data reading functions in these platforms are inefficient and, when used, they limit electronics acquisition rate capabilities. This paper explains a new low-cost, modular and open platform to read different types of sensors at high speed rates. Conventional reading functions are avoided to speed up acquisition rate, but this negatively affects data reliability of the system. To solve this and exploit higher data managing rates, a number of custom secure layers are implemented to secure a reliable acquisition. This paper describes the new low-cost electronics developed for high rate acquisition applications and inspects its performance and robustness against the introduction of an increasing number of sensors connected to the board. In most cases, acquisition rates of the system are duplicated using this new solution.
