The VIBRATIONS range enables clear and comprehensive learning of VIBRATIONS covering a variety of theories and topics. An understanding of the way in which materials and components react to excitation, is fundamental when studying the application of loads on a variety of fixed structures and rotating machinery. The VIBRATIONS range forms a comprehensive range of equipment, from simple pendulums, beam vibrations to complex structural vibrations. All are suitable for demonstration and experimental work.

All the VIBRATIONS hardware operates in a standalone mode, with some being supplied with Data Acquisition Interfaces and Software.



HVT14d Digital Spring Mass Vibration System

The HVT14 Spring Mass Vibrations Apparatus is a bench top or floor mounted unit to analyse the oscillations of a helical spring mass system. 

The spring can then be loaded with a number of set masses as well as having the option of testing the spring oscillations in free or damped conditions. The damped option requires the damper to be attached to the bottom of the spring, this too can be varied with different media to dampen the movement or by changing the dampening discs. The spring is then extended into a static loaded position and held in place via a locking mechanism.

The HVT14d is supplied with a sensor box and accelerometer sensor to trace the vertical movements of a freely vibrating spring. The spring is manually loaded into position, variable for standard experimentation include spring length (number of active coils), initial loading position, mass added to spring, damping pot and dampening discs.is set up with an accelerometer sensor which is used with the HVT14d sensor box that incorporates a digital oscilloscope.

HVT12c Beam Bending (Transverse) Vibration Module

Experimental module for the vibration analysis of transverse beam bending. The apparatus consists of two end fixings that support a beam. One end allows beam rotation only, whilst the other end allows rotation and horizontal movement only. The beam is forced to vibrate using a clamp on motor exciter supplied. This exciter operates from a high speed motor and has two eccentric masses attached at either end of the motor shaft. The rotation of the masses induces the excitation frequency of the beam. Additional masses can be added to the motor exciter to change the experimental parameters. The vibration of the beam is monitored using the sensor of the HAC190.

The HAC190 optional accessory is required to control the speed of the motor exciter and the HVT12k optional accessory to display the excitation frequency and output frequency.

 

Optional Accessories: HAC190, HVT12k, HVT12f

 

HVT12d Vibration Absorber

Experimental module, which fits into the HVT12f Vibrations frame (not supplied) making up part of the HVT12 Universal Vibration Apparatus.

HVT12f Vibrations Frame

The HVT12f Vibration Frame offers the ideal working frame for all of the HVT12 Universal Vibration experiment modules. Manufactured from high quality, ergonomic aluminium profile, it comprises solid side profiles for rigidly mounting experiment components. Dual upper and lower members create internal working dimensions of 1.22m x 0.76m for mounting experiments. Profile grooves create an accurate alignment of experiment components, and pre-assembled fasteners are integrated into the grooves for assembling of specific experiments within the HVT12 range. The HVT12f Vibrations Frame comes fully assembled with no need for tooling or lengthy assembly.

HVT12k Data Acquisition System

This unique and compact Data Acquisition System is an essential accessory for the HVT12 Universal Vibrations Apparatus experiments. When connected to the relevant experiment and its sensors, the system allows measuring, capturing, storing and analysing of experiment data.
