Definitions
- the invention presented concerns a device for generating mechanical vibration, intended primarily for dynamic compaction of various sorts of material.
- vibratory compaction equipment For compacting various materials, e.g., in the construction of roads, airfields, vibratory compaction equipment is used to increase the compaction capacity and optimise the result of the compaction work.
- Optimisation can consist, for example, of increasing the density of the material, increasing its bearing capacity, achieving a certain density profile with regard to depth and of obtaining a particular surface structure.
- the equipment used can, for example, be rollers that have one or more vibrating drums, self-propelled vibratory plates, vibratory pokers and tampers.
- the vibration be given varying frequency, amplitude and direction.
- a linear force vector is obtained by the two eccentrics rotating in different directions of rotation and fully synchronised, ie, at the same speed of rotation.
- the force vector can be controlled to act in varying directions.
- Phase displacement of the eccentrics is made by a mechanical system.
- Vibration frequency is set with the speed of rotation of the rotating eccentrics.
- Characteristic for present vibration systems is that they only permit some specific form of vibration and that complicated mechanical devices are required.
- the object of the invention presented is to optimise compaction with consideration to many different types of material being compacted using one and the same device.
- Figure 1 and 2 are schematic drawings of the device and figure 3 is a form of execution.
- the invention is characterised thereby, in that the generation of vibration is made by a system 1 of two or more so-called force vector cells 2 and where a rotating eccentric 10 in each force vector cell generates a circular rotating force vector.
- All force vector cells 2 generate a force vector that acts in the form of a resulting force vector on the common mass 3.
- Each eccentric 10 is rotated by a separate electrically controlled drive 11, e.g., electric motor, hydraulic motor, and where the angular position of each eccentric in relation to a reference direction is measured by an angle sensor 12 with electric output signal 9.
- a separate electrically controlled drive 11 e.g., electric motor, hydraulic motor
- Rotation of each eccentric with regard to rotation frequency, direction of rotation and phase position is controlled by a control and monitoring system 5 by a control signal 8 to the drive 11.
- a superior control device 4 determines signal 7, containing a rotation frequency, a direction of rotation and a phase position for each force vector cell 2 to achieve a determined resulting force vector diagram.
- the control devices 4 and 5 are at present based on microcomputers for advanced control and monitoring and simple re-programming of the vibration characteristics.
- the form of the resulting dynamic force vector diagram can easily be optimised with regard to factors such as the degree of compaction, direction of movement of the compacting appliance and the static force vector from the mass of the appliance.
- the invention also allows the force vector diagram to be "modulated” by varying the speed of rotation and phase position of the eccentrics in time.
- the invention described also allows an existing apparatus to be easily "re-programmed" to conform to force vector diagrams that have been tested and to new types of material that need to be compacted.
- Figure 4 Circular force vector diagram with adjustable amplitude: 105
- the vibration system consists of two force vector cells, where the eccentrics rotate in the same direction and at the same rotational speed and where the phase difference can be regulated.
- Figure 5 Force vector with adjustable direction and fixed amplitude, 115
- the vibration system consists of two force vector cells, where the eccentrics rotate in opposite directions and at the same rotational speed and where their phase position can be regulated.
- the figure shows how displacing the phase position 0, 90 and 45° in relation to the reference direction can turn the force vector.
- Figure 6 Force vector with adjustable direction and fixed amplitude, 125
- the vibration system consists of two force vector cells, where the eccentrics rotate in opposite directions and where eccentric 2 rotates at double the rotational speed compared to eccentric 1.
- the vibration system consists of three force vector cells, where the eccentrics 1 and 3 rotate in the same direction and eccentric 2 in the opposite direction
- the execution form according to figure 3 is a device with two force vector cells 2a, 2b, where the eccentrics have coaxial location. This implies that the outer eccentric 10a rotates round the inner eccentric 10b. This location means that the mass centre (centre of gravity) of the eccentrics has the same axis of rotation 17 and the same rotation plane 18, which is of significance for the resulting force vector for both of the eccentrics.
- axles 14a and 14b are carried by a number of bearings 16 so that they can rotate freely in relation to one another and to the holder 15.
- the principle of coaxial located eccentrics can also be used for 3 or more eccentrics.
- the cells are mounted on a common plate 3 the mass of which shall vibrate to compact the underlying material.
- the eccentrics 10a, 10b rotate with the respective axle 14a and 14b, which are common for the respective electric motor 11a, l ib and respective angle sensor 12a, 12b.
- the motor 1 la, 1 lb is fed from the control device 5a, 5b by a voltage 8a, 8b that determines the direction and speed of rotation for the axle 14a, 14b. From angle sensor 12a, 12b a signal 9a, 9b is given that is the angle value of the eccentric
- the signal 7a, 7b from the control device 4 is the desired value for the direction of rotation, speed of rotation and phase position for the eccentric 10a, 10b. 170
- the control device 5 a, 5b calculates the value of the real direction of rotation, speed of rotation and phase position for the eccentric 10a, 10b. Consequently, these values form the actual value of the control 175 system.
- the control device 5a, 5b regulates with the voltage 8a, 8b the electric motor 11a, 1 lb so that the desired value and the actual value are the same.
- the parameters can for example be the frequencies for the vibration, form of the force vector diagram and modulation.
