Sep 01, 2019 · Vibration measurements should be made when the tractor is driven at speeds of 10 km h−1, 12 km h −1 and 14 km h −1 over the 100 m smoother track (ISO 5008). The effects of vibration on the comfort of a person exposed to periodic, random or transient vibration are assessed in the frequency range 0.5–80 Hz.

Abstract. The traditional wheel loader is built without any axle suspension and experiences severe vibration. Three different layouts of hydropneumatic suspension, namely, unconnected strut (UCS), interconnected in roll plane (IC-R) and interconnected in roll and pitch plane (IC-RP), are installed on the wheel loader to improve ride comfort.

The results show that both the vertical and lateral vibration acceleration responses of a carbody with the Shinkansen wheel in contact with the UIC60 rail are stable and lower than those for the JIS60 rail. Furthermore, the UIC60 rail provides a better degree of ride comfort to passengers when matched with the Shinkansen wheel.

Oct 01, 2013 · Two standards, ISO 2631-1 (1985) and ISO 2631-1 (1997), were used to assess the effect of wheel loader vibration on comfort. The assessment results of ISO 2631-1 (1985) showed that vibration in the frequency range from 4 to 20 Hz in the vertical direction and in the frequency range from 1.6 to 3.15 Hz in the vertical and driving directions plays an important …

A multi-body dynamic rigid-flexible coupling model of an in-wheel motor vehicle is built. This vehicle is based on a particular class-A car. An overall investigation of the influence of unsprung mass on vehicle ride comfort is conducted. With the increment of unsprung mass, overall vehicle ride comfort is decreased. The degradation of wheel dynamic load performance is most obvious.
