The Research And Analysis On Riding Comfort Of Vehicle Carrying Optoelectronic Theodolite

Automotive ride comfort is one of the most important indexes to evaluate automotive performance.This thesis studies the automotive ride comfort according to the anti-vibration requirements of the optoelectronic theodolite based the tests on asphalt pavement and gravel road with three different speeds.A whole multi-body dynamics model will be built up in this thesis including suspension,body,optoelectronic theodolite,tires and etc.Then simulates the model and analysis data on the ride comfort.And then,through the actual car in the real road surface measurement of the actual test conditions,get the corresponding measured data.We can analysis the influencing factors by comparing the experimental data and simulation data,and analysis the influence of ride comfort about the vehicle carrying optoelectronic theodolite.At last,on the basis of the dynamic model about vehicle carrying optoelectronic theodolite,I propose an option to improve the ride comfort in adding to a vibration reduction mechanism.The improvement results show that the vibration acceleration of the relative points in the optimized model is obviously lower than that of the improved one.With the conclusions studied in this thesis about ride comfort of vehicle carrying optoelectronic theodolite can be used in future as a theoretical reference research on riding comfort.
