The effects of vibration acceleration on visual identification were researched through simulation experiment. A function model for the relation of acceleration to the visual identification efficiency (the response time of correct identification) was established. The results show that vibration acceleration has a significant influence on visual identification efficiency, and their relation can be described by an exponential function. The results offered experimental parameters for vibration reduction design of visual display equipment in vibration environment, and put forward a new idea for vibration reduction.

Optimal Design of Automobile’s Vibration Absorber

   2011, 31 (6): 123-126.   DOI: 10.3969/j.issn.1006-1355-2011.06.027

The purpose of this work is to formulate the analytical solution for the mathematical models of single and double vibration absorbers, and to establish the design procedure for developing the absorbers. Based on the mathematical models, the computer programs for tuning absorber mass, stiffness and damping are written. Finally, the absorber is made and applied to a vehicle. The test result shows that the structure-borne noise can be reduced obviously. The optimal design of the absorber’s parameters can be done very fast with this analytical solution, thereby large amount of computer time and engineer’s effort can be saved.
