Product Details

This apparatus is designed to study the whirling phenomenon and critical speed of rotating shafts, allowing students to observe how shafts vibrate and enter resonance due to rotational imbalance at specific speeds. It enables the investigation of how factors like shaft length, diameter, and bearing conditions influence the natural frequency and critical speed. The unit features a variable-speed motor with digital control and an LCD display, allowing precise adjustment of rotational speed. It includes a set of six tensile steel shafts with different diameters and lengths, along with three bearings that can be repositioned to vary the support conditions. The entire mechanism permits clear observation of the bahaviuor of shaft as it approaches and passes through its critical speed. Its primary application is in mechanical engineering education for teaching vibration analysis and rotor dynamics. The key benefit is the hands-on investigation of resonance and self-alignment in rotating systems, enabling students to determine critical speeds experimentally and understand their critical role in preventing catastrophic failures in machinery such as turbines, compressors, and drive shafts.
