The GUNT Elastic Shafts Experimental Unit is designed to investigate critical speed, resonance, and natural modes in rotating systems. It provides a hands-on approach to studying elastic shaft behaviour using simplified models and visual demonstrations. The unit enables users to explore the dynamic response of rotating shafts and understand how operating conditions affect system vibrations.
Product Features
- Demonstrates resonance and critical speed phenomena in rotating shafts using visual and measurable methods.
- Includes two simplified shaft models: one with uniformly distributed mass and one with massless shaft sections and discrete mass disks.
- Enables study of natural vibration modes and the distinction between supercritical and subcritical operating states.
- Six interchangeable shafts of varying lengths and diameters for testing different configurations.
- Shafts mounted in up to four self-aligning ball bearings; mass disks can be added to simulate Laval rotor systems.
- Axial position readings taken from a parallel-mounted scale for accuracy.
- Three-phase motor with flexible coupling drives the shaft; speed is electronically controlled and digitally displayed.
- Speed adjusted via dual potentiometers, allowing fine-tuned experiments across the full operating range.
- Transparent safety cover and integrated safety bearing provide secure operation during high-speed experiments.
- Optional data acquisition system available for digital measurement display and PC-based analysis.
Benefits
- Improves understanding of critical speed risks and resonance control in rotating machinery.
- Hands-on experiments reinforce theoretical concepts in shaft vibration and rotor dynamics.
- Ideal for engineering education and mechanical training programs focusing on machine dynamics and system design.
- Flexible and modular design allows for versatile testing of shaft configurations and load conditions.
