How to choose a small walking roller according to the pressed material? There are many aspects to consider when choosing a small walk behind roller. Today Shandong Jinyao Construction Machinery Co., Ltd. will tell you how to choose the material to be pressed: 1. For compaction of rockfill, large tonnage rollers should be used instead of large ones. 2. For compaction of clay, it is best to use a compacted roller. 3. For the compaction of the mixture, try to select a vibrating roller to mix the materials evenly. 4. Real-time deep lamination, the roller machine manufacturer recommends that the heavy-duty vibratory road roller should adopt slow rolling, and the shallow layer should adopt static pressure roller. Small hand-held road roller vibration wheel vibration reduction support system The small hand-held road roller has the dual characteristics of vibration and vibration reduction. On the one hand, the rotation of the vibration mass in the vibrating wheel generates periodic vibration, which acts on the soil to be grounded, so that the soil has the required function, and on the other hand, the vibration of the vibrating wheel is reduced. Transfer to the frame and other vehicle systems to improve the operational function and comfort of the vehicle. The main task of the small hand operate road roller compactor is to reduce vibration transmission. The vibrationdamping 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 first-stage damper, which affects the vibration working and working state of the vibrating wheel. On the other hand, the vibration excitation and vibration of the vibration wheel are excited by the vibration-damping support system, which greatly reduces the vibration level. Between the vibrating wheel and the frame system, the same section of rubber with different settling methods is reduced. The vibrator constitutes a vibrating wheel damping support system. According to the planning characteristics and application requirements of the vibration wheel, the rubber damper has different forces, so its dynamic stiffness also has different characteristics. Motion Analysis of Vibration Wheel Damping System Rubber shock absorber elastic spindle 1. Rubber Shock Absorber The elastic axes X, Y, Z refer to a rubber damper on three shafts that are supported along the edge. In the case of an axial load, only the displacement in the load direction occurs, and three orthogonal axes orthogonal to the angular displacement do not occur. 2. The elastic center O of the rubber damper refers to the intersection of three orthogonal elastic main shafts and a rubber damper.
The rubber damper has a simple cross-sectional shape, the elastic main axis is a symmetry axis, and the elastic center is a centroid direction. The single rubber damper in the vibrating wheel damping support system, due to the symmetry of its circular cross section, the elastic main axes X and Z have the same mechanical properties and are subjected to shear loads. Dynamic testing yields dynamic functions. The elastic main shaft Y can withstand tensile and compressive loads, and its corresponding mechanical function Young's modulus F can be based on the Poisson's ratio of the rubber material. The shear modulus G is determined. (1) Vibration wheel rigid body inertia spindle (2) The inertia main axis of the road roller refers to three axes of x, y, and z perpendicular to the center of gravity of the mass inertia product. The triaxial mechanical analysis represents the motion of the vibrating wheel in the corresponding direction. (3) The center of gravity of the vibrating wheel is the intersection of the three axes of inertia. The vibrating wheel is a simple cylinder with a symmetrical cross section, and its main axis of inertia and center of gravity can be determined according to the symmetry of the plane. https://www.jinyaoexcavator.com/
