ABSTRACT

This paper refer to the study of applying dynamic vibration absorber to reduce the
effects of vibration on human body, based on the oscillator model of human body as a
mechanical- biological system. Using the theory of constrained non-linear programming to
calculate the parameters of dynamic vibration absorber installed in oscillatory system with
many degrees of freedong, significantly reducing vibration effects caused by structures and
trangsports on human body, then buiding a scientific basis for desingning vibration-reduction
mechanism and equipment in occupational safety.
