Xia belt bulldozers run "unpaved" d

Xia belt bulldozers run "unpaved" due to the effects of unevenness in the ground and workloads cause strong vibrations and shocks on the dozer's running mechanism and change according to the operating conditions of the bulldozer to 8 Hz, and the frequency of response to the vibration load that has the greatest impact on the bulldozer after the bulldozer excitation test is less than 15 Hz. The natural frequency of the primary is approximately 4 Hz, the natural frequency of the second stage is approximately 10 Hz and the oscillation of about 4 Hz is the main frequency. Studies have shown that the natural frequencies of the human spine, upper body, of the heart, arms and other parts are between 2 and 6 Hz and that the vibrations of a spinal machine without vibration damping can affect the health of the driver.
