Product Details

This apparatus is designed to study the fundamental principles of free and forced mechanical vibrations, allowing students to investigate the natural frequency of a system, observe the phenomenon of resonance, and analyze the effects of damping. It provides a comprehensive platform for understanding vibrational behavior in beams. The unit features an aluminum frame supporting a cantilever beam oscillator. A set of three interchangeable coil springs with different stiffness constants allows the system natural frequency to be varied. A variable-speed exciter motor is used to apply forced vibrations, and a digital sensor measures the resulting oscillations. A key component is the drum recorder, which plots the beam amplitude versus time on graph paper, providing a clear visual record of the vibration, including the resonant peak. Its primary application is in mechanical and civil engineering education for teaching structural dynamics and vibration analysis. The key benefit is the hands-on observation of resonance and damping, enabling students to experimentally determine natural frequencies, understand the critical role of resonance in structural failure, and learn methods for vibration control in real-world engineering systems.
