Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The principle of traditional vibratory compaction machinery such as figure 1 As shown, the high-frequency vibration generated by the vibrator fixed on an object is transmitted to the pressed material to make it vibrate, and the small particles are filled into the pores of the large particles, and the degree of compaction increases.

[0033] The method of the present invention adopts a single motor and a transmission system to realize unidirectional non-periodic vibration, and the specific method is:

[0034] 1) Select the motor and controller

[0035] Use permanent magnet synchronous motor or asynchronous motor, and adopt appropriate control method to make the motor speed a non-periodic signal;

[0036] The direct delay feedback control method can be used to make the motor speed appear aperiodic motion, and the direct delay f...

Abstract

The invention provides a generation method of one-way aperiodic vibration of a single motor, which comprises the following steps: selecting a motor and a controller; using a direct delay feedback control method to enable the rotating speed of the motor to be in aperiodic motion; and designing a transmission part, four symmetric eccentric wheels and a base contacted with a compacted material so asto realize that the four eccentric wheels rotate reversely in the same aperiodic rotating speed. A one-way aperiodic vibration device of the invention comprises a base, and the eccentric wheels, the transmission part and the motor which are supported and fixed on the base through a support, wherein, the transmission part consists of a driving bevel gear, two driven bevel gears, two driving pulleys, four driven pulleys and a clutch, and the transmission part can realize reverse constant velocity rotation of two groups of the eccentric wheels. The method and the device of the invention have theadvantages that the single motor is taken as a power source and the four biaxial eccentric wheels are taken as rotors to generate one-way aperiodic vibration, vibration amplitude is adjustable, frequency spectrum is broad and adjustable, better material resonance can be generated and compacting efficiency is higher.

Description

technical field [0001] The invention relates to a method for generating unidirectional aperiodic vibration, in particular to a method for generating unidirectional aperiodic vibration by using a single motor and a transmission system. The invention also relates to a unidirectional aperiodic vibration device. Background technique [0002] Compaction machinery is an essential construction equipment for foundation construction, dam and port construction, airport construction, mine construction, forest area construction and other projects. Effective compaction can significantly improve the bearing capacity and stability of filling and foundation works, and reduce or eliminate the hazards caused by subsidence. Since the first self-propelled steam roller appeared in the world in 1862, the road roller has a development history of more than one hundred years. During this period of time, compaction machines such as static steel wheel rollers, tire rollers, vibratory rollers, vibrato...
