Shock absorber block of road roller for construction machinery
Roller is the most common road construction machinery and equipment, good horse with a good saddle, a good mechanical equipment must have good use of the environment and perfect parts, in order to better play its talent.
Vibratory roller is the main construction machinery used in pavement, subgrade and other construction. It there is a contradiction between the vibration and damping: on the one hand to rotate to generate periodic vibration by eccentric mass in vibration wheel, by vibration of the soil, improve the soil properties, on the other hand to reduce the transfer to the frame on the vehicle system vibration wheel vibration, and improve vehicle handling performance comfort.

The performance of rubber shock absorber is mainly the damping effect on the vibration system. This kind of damping originates from the interior of the medium and the research level of solid physics. At present, the internal damping of solid materials can not be calculated quantitatively according to the basic physical parameters of solid medium, and the internal damping of solid materials can only be measured by experimental methods under specific conditions.
All levels of vibration unit of vibratory roller is the main working parts meet the requirements of vibration transfer, the rubber damper vibration wheel and frame is vibration damping supporting wheel, change its performance parameters with the size of the vibration wheel working condition changes. It is necessary to determine the dynamic performance parameters of the rubber damper for various research of vibratory wheel and vibratory roller.

The dynamic performance of rubber damper is different from its static performance, but also influenced by other factors such as material composition, temperature, oil, aging, sunshine, but on the vibratory roller vibration roller and the frame of special applications, rubber damper working state change is mainly reflected in the combination of different vibration wheel work the amplitude and different working frequency.
It is a feasible and reliable analysis method to analyze the dynamic performance of rubber shock absorber by using advanced test equipment to simulate the dynamic working load of rubber damper, and then determine the performance parameters of rubber shock absorber. The performance parameters of the rubber damper under different working conditions as the component parameters of the rubber shock absorber are the theoretical basis for the comprehensive selection of rubber shock absorber of the vibration damping system of the vibration wheel support system.
