The working environment of construction machinery is generally poor, in order to carry out the research work on seating comfort of construction machinery. It is of great significance to improve the working conditions of construction machinery drivers, improve work efficiency, ensure good health, improve ride comfort design of water products, and improve the market competitiveness of the construction machinery machine.
What is a vibration system
The vibration system includes two parts: the vibration table body and the electrical control. Its vibration principle uses a non-forced-guided inertial excitation system. The vibrator is placed on four connected air springs to form a typical two-degree-of-freedom vibration system. During work, the four groups of unbalancers rotate in the opposite direction. The centrifugal force generated when the eccentric mass rotates is synthesized upward in the direction of vibration to form an exciting force that changes according to a sine law, and the components perpendicular to the vibration direction cancel each other out. When vertical vibration is performed and the eccentric mass of two of the two unbalancers is adjusted by 108 degrees in the rotation direction, the table surface vibrates in the horizontal direction. After the vibration table is determined to be reloaded, it is only necessary to adjust the position of the eccentric mass along the normal direction of rotation in the unbalancer, and adjust the magnitude of the unbalanced moment to change the amplitude of the vibration amplitude. The adjustment adopts a hydraulic transmission method.
