Description
The utility model relates to a kind of mechanical vibration test unit, and particularly a kind of vibration experiment that produces simple harmonic quantity (sine) vibration that frequency and amplitude can change, can satisfy high science and engineering and normal colleges and schools requires and electrician, electrical instrumentation, particularly transportation and power machine instrument are carried out the multi-functional mechanical vibration testing device that vibration experiment requires.
The core of mechanical vibration test unit of the prior art is one and produces frequency and equal sine wave oscillations system and an excitation system and the excitation system that can control of amplitude.For example: " mechanical vibration and control experimental provision " that " mechanical vibration and the vibration control combined test apparatus " that University Of Chongqing produces, Northwestern Polytechnical University produce, instrument plant, Baoying County's vibration instrumentation factory produce in northwest Machines Plant, Suzhou Test Device Factory, the Hunan shaking table and vibrator, and Denmark B﹠amp; K company, Japanese SHINKEN company, the DERRITRON company of Britain, the DICKIE company of the U.S. etc. are the similar testing equipment of manufacturers produce both at home and abroad, adopts two strutbeams, semi-girder, pendulum spring or support spring to constitute the system that produces sinusoidal vibration mostly.Though adopt the product of these vibrational systems to satisfy to produce and the requirement of scientific research,, the shortcoming of their maximums is a complex structure, and the manufacturing cost height is handled and is used trouble, damages easily, and inconvenience is keeped in repair.Therefore, be difficult in widespread use in medium and small enterprise and the education experiment.
The purpose of this utility model provide a kind of compact conformation, multiple functional, handle characteristics such as simple, durable in use, can satisfy education experiment and medium and small enterprise needs multi-functional mechanical vibration testing device.
The purpose of this utility model is achieved like this: promptly a kind of multi-functional mechanical vibration testing device is characterized in that: comprise a cross swing arm spring device, an exciting agency, a single disk rotor mechanism; Wherein the two ends of a swing arm in the cross swing arm and support are the supporting of the thimble conical surface, and the two ends of another swing arm are supported by spring; The eccentricity excitation disk of exciting agency is rack-mount by its rotating shaft, and is installed in the cross swing arm by support, and rotating shaft is connected with change speed motor by rotating mechanism; Single disk rotor mechanism is made of table roller and rotating shaft thereof, and an end of rotating shaft is bearing on the support by bearing, and the other end is connected with machine shaft with the belt pulley coupling band by elastic coupling.
In the above-mentioned multi-functional mechanical vibration testing device, be supported in " spring mass system " that two cross swing arms on the spring are formed, under the effect of the centrifugal inertial excitation power of eccentric mass, will realize doing sinusoidal vibration by the vibration regularity of single-mode system in the mechanical vibration theory around the axis that two centre holes connect.The disk that produces the centrifugal inertial excitation power of eccentric mass is by the motor drives of belt by variable velocity.Simultaneously, the clutch coupling that shaft coupling and coupling band constitute makes variable-speed motor also can drive the transverse vibration that the single disk rotor system realizes axle.
Used different fully of the cross swing arm vibrating mechanism that the utility model adopted and domestic and international product in the past.It only need with a cross swing arm and two independently volute spring form, so structure is simple especially, directly perceived, handling ease, cost are low, reliable and stable, be convenient to keep in repair.In addition, it produces exciting force with the motor of vibrator and band eccentric mass unlike other products, but makes the rotation of eccentricity excitation disk produce sine excitation power by belt.Like this, not only can utilize the inertia of eccentricity excitation disk to make the vibrational waveform of output stable and, but also can make same motor drives rotor-support-foundation system realize transverse vibration as the inertial mass of vibrational system.In addition, the utility model also adopts conical surface supporting to replace complicated in the past support pattern, thereby has avoided the gap and misaligned influencing waveform quality, and this simple in structure, it is also easy to process.
Structure of the present utility model can further specify by the embodiment that accompanying drawing provides.
The utility model structure has following accompanying drawing:
Accompanying drawing 1 is a main cut-open view of the present utility model;
Accompanying drawing 2 is side views of the utility model structure.
Referring to accompanying drawing: the multi-functional mechanical vibration testing device comprises a cross swing arm spring device among the figure, an exciting agency, a single disk rotor mechanism; Wherein the two ends of a swing arm 4 in the cross swing arm and support are the supporting of the thimble conical surface, and the two ends of another swing arm 5 are supported by spring 6; The eccentricity excitation disk 3 of exciting agency is rack-mount by its rotating shaft, and is installed in the cross swing arm by support, and rotating shaft is connected with change speed motor 1 by rotating mechanism; Single disk rotor mechanism is made of table roller 7 and rotating shaft thereof, and the two ends of rotating shaft are bearing on the support by bearing, and the other end is connected with machine shaft with belt pulley coupling band 9 by elastic coupling 8.
In the rotating shaft on the eccentricity excitation disk side in the said apparatus prototype gear 10 is installed; The rotating shaft of eccentricity excitation disk 3 is connected with the rotating shaft of motor 1 by the belt pulley and the belt 2 of axle head; Eccentricity excitation disk 3 and table roller 7 have the cover of going up 11,12 respectively; The support of cross swing arm spring device, the last cover of table roller all are fixed on the base 13.
The principle of work of said apparatus is such: the A.C. series motor 1 of speed variable drives the eccentricity excitation disk 3 that is supported in the cross swing arm by belt 2 and rotates, and makes cross swing arm 4 do small sinusoidal vibration around conical surface supporting center thereby produce sinusoidal interference moment.Two-end-point A, B on it can regard straight-line oscillation as, and the frequency of its vibration is to realize by the input voltage of pressure regulator change motor, the amplitude of its vibration, and the quality inertia of the rigidity of available change spring or swing arm is regulated.A, B electrodynamic type speed vibration transducer is installed at 2 respectively, just can be taken out relevant measuring-signal at the other equipped with non-contact magnetic induction sensor of prototype gear.If belt 2 is unloaded, after tightening the trip bolt between elastic coupling 9 and the belt pulley coupling band 8 again, motor just can drive table roller rotating shaft 7 rotations, makes rotating shaft produce transverse vibration, cover the equipped with non-contact magnetic induction sensor on the table roller, just can carry out the critical speed of shaft experiment.
The vibration experiment that the utility model can satisfy high science and engineering and normal colleges and schools requires and electrician, electrical instrumentation, and particularly transportation and power machine instrument are carried out the requirement of vibration experiment.
