Structure Design and Analysis of Cable Shearing Tool for Temperature Measuring Element in Pulsed Reactors

This paper introduces the design requirement and characteristics of the cable shearing tool for the temperature-measuring element in pulsed reactors. Accrording to the characteristics of the cable shearing and the man-machine engineering theory, a shearing structure scheme is proposed, in which the shear motion is combined with up/down motion and the rotation,and the scheme of the force-amplification structure is the centric slider-crank connecting rod mechanism combining with lever mechanism. Then mathematics model is built and the computation of using interpolation for typical working conditions is finished based on the model. The computation shows that the scheme is reasonable and feasible, with the advantages such as small space, big mu-factor, and easy and safe operation.
