Description
Technical field
The utility model relates to measuring flatness of road surface equipment technical field, is specifically related to a kind of device for measuring surface evenness.
Background technology
The flatness on road surface is related to the safety of driving, the size of wheel impacts power suffered by the comfortableness taken and road surface.Irregular road surfaces can increase car resistance, and makes vehicle produce additional effect of vibration.This effect of vibration can cause vehicle pitching, the speed of impact driving and safety.The method of testing of surface evenness has that three meters of ruler methods, eight take turns smoothness measuring equipment method, accumulative of jolting and laser optical method, is more accurate with laser testing method.
Because actual road surface is up-and-down, in testing flatness process, front/rear frame often produces a small height difference because road surface is uneven, at this moment balance beam will tilt.When not considering that balance beam tilts, the displacement that laser range finder records is in the process of data processing, all the time be the value (as Fig. 1) when thinking that balance beam is in horizontality, therefore, this metering system Problems existing is: assuming that test travel direction is forward, when then balance beam leans forward, detect shift value less than real displacement value; On the contrary, if balance beam hypsokinesis, detect shift value again larger than actual displacement value (as Fig. 2).
