Problems solved by technology

However, due to the diversity of the compacted material and the difference in particle size and composition, its natural frequency is a frequency domain with a wide range. Even if the vibration frequency and amplitude are changed during the compaction process, the exciter will There is only one vibration frequency and its corresponding amplitude. This single-frequency vibration mode is difficult to achieve the expected effect of resonant compaction on the compacted material.

Abstract

The invention refers to a vibration stress method used to stress the architectural or road material and a vibrator of vibrant stress machine which is used to put the method in practice. The character of the method is that set two or more spin eccentric axes whose eccentricity is different from the speed of spin in the vibrator, the axes can output many vibrant strength at any times. The strength used to stress the material, and its frequency and swing vary from each other, it can achieve the resonant stress effect. The character of the multivibrator is that in the box of the vibrator there are two or more spin eccentric axes whose eccentricity is different from the speed of spin, the axes are connected one to another by vary speed gearings, one of the axostyle connected to the outside force output axes by gearing. The invention have the merits of simple structure, efficiency, good stress effect and so on, adjusting to stress work of many material as well.

Description

Technical field [0001] The invention belongs to the technical field of construction and road construction machinery, and relates to a vibration compaction method for compacting and strengthening construction or road construction materials and an exciter for a vibration compaction machine for implementing the method. Background technique [0002] Compaction is the main means to strengthen the foundation of engineering structures, dams and pavement layers. In recent years, in order to adapt to the diversity of compacted materials and the constant changes in the physical-mechanical properties of materials during the compaction process, and to improve the compaction efficiency and compaction degree, people have adopted a variety of working methods, such as using variable frequency and amplitude Advanced vibration compaction technology, etc., in order to change the vibration frequency and amplitude in different compaction occasions. However, due to the diversity of the compacted...
