Center of the Exciting Force of a Machine in China and Center Offset of Vibrating Body However, the transition time of the starting process can not be too long, otherwise it will reduce the effective compaction time. At the same time, too long start-up time, will make the vibrating wheel vibration from the resonant point when the resonance phenomenon, which is the machine and the pressure material is very harmful [6]. A similar phenomenon is also present when the machine is out of service. At the same time, abrupt changes in external loads at start-up and shut-down can cause engine speed and power to fluctuate. In particular, the large inertia of the machine causes the engine Drag the brake, which will not only affect the performance of the engine, and will reduce the engine reliability and service life. Figure 3 for the forward speed up the process of starting the engine speed and walking drive system power curve; Engine speed and traveling system power curve in the process of acceleration ???? Comparison test results show that the impact of the vibrating wheel vibrating force center face and the vibration center of the degree of coincidence is the impact of the amplitude of vibration wheel uniformity of the key factors in the design and manufacture of roller must be strictly controlled elements. From the use requirements, on the one hand requires the vibration parameters of the front and rear vibration wheel should be the same, but also require these vibration parameters along the lateral value of vibration should also be basically the same, the maximum deviation should not exceed 5%. ultrathin asphalt paver online dealers<br> concrete trowel marketing manufacturers<br> types of road paving equipment<br> asphalt tack coat for sale |
