Research on relation between two evaluation methods of random input ride comfort for off-road vehicle

Based on ISO standard 2631 and average absorbed power method, the data of half-load sand road test of EQ2050 are processed, and the overall weighted acceleration RMS and average absorbed power are calculated respectively. By using the least squares method, the relation between the two evaluation ind...

Description
Summary:Based on ISO standard 2631 and average absorbed power method, the data of half-load sand road test of EQ2050 are processed, and the overall weighted acceleration RMS and average absorbed power are calculated respectively. By using the least squares method, the relation between the two evaluation indexes is fitted and the estimation formula of average absorbed power is proposed. By changing the load of vehicle or the test road, the vehicle is tested and the accuracy is verified. The results show that the estimation formula is independent of loading and road and it can be used to realize the rapid estimation of average absorbed power of off-road vehicles.
