Vibration Effect of Small Vibratory Roller XCMG XS400J

There is a hostility between vibration and vibration reduction in vibratory rollers. On the one hand, the rotation of the large mass in the vibrating wheel should be used to generate periodic vibrations, which act on the soil being vibrated to make the soil have the required functions. On the other hand, the vibration of the vibrating wheel should be reduced. Transmission to the frame and other vehicle systems to improve the vehicle's operating performance and comfort performance. The main task of the vibration damping links at all levels in the vibratory roller is to reduce vibration transmission. The vibration-damping support system between the vibrating wheel and the front frame is the most important vibration-damping link in the vibration-damping system of the vibratory roller, also known as the primary shock absorber. On the other hand, after the vibration of the vibrating wheel and the unevenness of the road are transmitted through the damping support system, the vibration level is greatly reduced. Between the vibrating wheel and the frame system, multiple rubber dampers with the same cross section in different placement The vibrator constitutes the vibration damping support system of the vibrating wheel. According to the design characteristics and application requirements of the vibrating wheel, the stress of the rubber shock absorber is different, so that its dynamic stiffness also has different characteristics.
Motion Analysis of Vibration Wheel Damping Support System

Elastic spindle with rubber shock absorber

1. The elastic axis x, y, and z of the rubber shock absorber refer to the three axes on a single rubber shock absorber.

When the load in the axial direction occurs, only the displacement along the load direction occurs, and the three perpendicular axes that do not occur angular displacement.

2. The elastic center O of the rubber shock absorber refers to the intersection of three orthogonal elastic principal axes on a single rubber shock absorber.

For a rubber shock absorber with a simple cross-sectional shape, its elastic principal axis is its symmetry axis, and its elastic center is the position of its centroid. Due to the symmetry of the circular section of the single rubber shock absorber in the vibration damping support system, the elastic main axes X and Z have the same mechanical properties, and both bear the shearing work load. The dynamic function is obtained by the dynamic test. The elastic main axis Y can bear tension and compression loads, and its corresponding mechanical function Young's modulus F can be based on the Poisson's ratio of the rubber material. and the shear elastic modulus G

(1) The main axis of inertia of the vibrating wheel rigid body

(2) The main axis of inertia of the vibrating wheel refers to the three vertical axes passing through its center of gravity, x, y, and z without mass inertia products. The mechanical analysis of the three axes represents the movement method of the corresponding direction of the vibrating wheel.

(3) The center of gravity of the vibrating wheel is the intersection of the three inertial axes.

The vibrating wheel is a simple cylinder with a symmetrical cross-section, and its inertial axis and center of gravity can be determined according to the symmetry of the design.
