Design of Earthquake Shaking Table (EST) Using Ball Screw Guide Linear Actuator

摘要

Earthquake shaking table is one of the tools used to simulate earthquake behavior and its effect for the structures. This research describes a process of designing a dual-axis shaking table using ball screw linear guide actuator as its main actuator. The system utilizes Bressenham algorithm for controlling both actuators synchronously. ZX gesture and motion sensor is used to monitor every movement from the table. The main controller uses ARM Cortex M4 microcontroller to ensure fast movement and response for both actuator and sensor system
