This classification covers vibration testing machines used for durability and reliability evaluation of products and components in manufacturing industries. Using excitation devices such as electromagnetic vibration testers, hydraulic vibration testers, and mechanical vibration testers, these systems perform sine wave vibration, random vibration, and shock testing to support quality inspection and product development for automotive parts, electronic devices, and mechanical components. Testing compliant with JIS and IEC standards is possible, and these machines are used in combination with acceleration sensors and data loggers. Unlike acoustic measurement equipment, these are clearly distinguished as testing devices that actually generate vibrations to apply loads to test objects.
