abstract = "An over current protection circuit breaker with selective protection is designed in this paper. We carry out motion simulation for the whole mechanism based on ADAMS. We observe and analyze the feasibility of the motion of the mechanism. And then the motion curve of important parts
and the contact force curve of the important contact area and the curve of the force and torque of the spring are obtained. We have carried on the noise signal analysis to these curves by signal processing method, the computation and the simulation result show that the mechanism simulation
conforms to the design expectation, through the simulation and signal analysis result we can find that the area where contact force is larger and the material of it needs to be strengthened. At the same time, the stiffness coefficient of each torsion spring and tension spring is different.
The simulation results can provide the selection and matching of the coefficients of the spring and the torsion spring in order to ensure the reliability of the motion mechanism, accurate and stable. Overall, this product has no significant impact on the whole body.Through signal analysis,
we find that its motion is stable and its design is reasonable.",
