dc.description.abstract | With proper design of geometric configurations and spring constant, a spring counter-balanced mechanism is capable of achieving static balance at arbitrary point by reconciling the variation of potential energy with the elastic potential energy. Since the mechanism absorbs the variation of potential energy spontaneously, it takes less effort to move objects so that the dependence on extra power sources can be diminished. And thus, we can reduce the wear and tear from the friction of mechanism.
In this study, a spring balancing method on the base according to the potential energy transformation theory will be developed. The novel configurations of complicated link structure can simply be established on the topological design. By significant functional requirements, novel configurations with priority properties will be determined to replace the existing two-bar and four-bar spring balancing mechanisms. The geometric relations among link lengths are derived to construct the mechanism which is corresponded to the required novel configurations. And with the mathematical principles, the spring constant can be directly obtained to accomplish the desired static balancing mechanism. | en |
