The knapsack dynamic load Reduction of Students' Study Load that the components such as beam 2, lower beam 14, backboard 7, spring 13, drawstring 6, guide rail 5 and the frame that is slidably connected are constituted
Device 201, knapsack 202, knapsack 202 are linked together by the knapsack link block 10 on knapsack dynamic load burden-alleviating device 201.
Therefore, the weight in knapsack, be slidably connected frame and spring 13 constitutes damping mass oscillatory system.When people's walking
When, since the walking of people substantially belongs to inverted single pendulum form, mass center of human body has certain displacement in the vertical direction, works as people
When body bears weight walking, knapsack, which is applied to the power with human body, to become a dynamic with this displacement of mass center of human body
Power, this dynamic force are the power changed with walking period, and peak value may be the several times of knapsack gravity, and peak value is bigger, human body shoulder
The sense of discomfort at the positions such as wing, joint of lower extremity can be stronger.When people bears knapsack dynamic load burden-alleviating device 201 and the walking of knapsack 202
When, mass center of human body displacement is equivalent to the damping mass oscillatory system being made of the weight in knapsack, be slidably connected frame and spring 13
Displacement input, so as to cause the vibration of damping mass.
Spring-damp system in said mechanism walks the difference of dynamic frequency using spring-damp system intrinsic frequency and human body
It is different, reach certain when forming the frequency ratio that spring-damp system intrinsic frequency walks dynamic frequency with human body by weight, guide rail and spring
After numerical value, the dynamic load from weight that human body walking bears body will be greatly reduced, and achieve the purpose that Reduction of Students' Study Load.
In conclusion when a kind of knapsack dynamic load burden-alleviating device of the invention is vibrated using damping mass and trunk
The difference of the two frequency and phase realizes the purpose of Reduction of Students' Study Load, improves the efficiency of operation, mitigates the burden of field operator.
