Road surface accelerating loading experimental device

Abstract

The invention provides a pavement accelerating and loading experimental device, pertaining to experimental facility field. The invented device comprises a main framework, and a rail assembly connected to a rolling assembly is disposed on the main framework. The invented device is characterized in that the rolling assembly comprises both a drive wheel connected to the power device and more than one driven wheels disconnected from the power device, thereby pavement rolling status when vehicles run thereon practically can be reproduced better to enhance accuracy of experimental conclusion and efficiency of the experiment. The invented device is also characterized in that the outer circular surfaces of the loading steel wheel and the return-stroke steel wheel are provided with outwards inclined treads, auto direction guide is implemented, and cylindrical wheel guide is not needed, so that structure is simplified and noise is decreased.

AI Technical Summary

Benefits of technology

This new design for an accelerating testing machine uses dual axles that improve its performance by simulating different conditions such as turning or braking while also reducing power usage compared to previous designs without any extra components like steering systems. It achieves this through improved roll behavior and reduces vibrations caused when moving over uneven surfaces. Additionally it simplifies the construction process making sure everything stays stable even if some parts get stuck due to heavy traffic. Overall, these technical improvements result in more accurate data collection from vehicles being tested.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the accuracy of detecting cracks on roads during acceleration tests due to differences caused by different types of loadings applied over time compared to previous designs that had been tested without any significant changes made after they were installed onto them.
