Abstract

TiNiNb shape memory alloy ring is installed on the circuit breaker operating mechanism to enhance the intensity of the operating mechanism by means of the memory effect and superelasticity of the ring.In this paper

the stress intensity of the circuit breaker operating mechanism enhanced by TiNiNb shape memory alloy ring is investigated.The initial parameters and hole enlargement process of the alloy ring are offered

then a mathematical stress intensity model of the simplified shape memory alloy ring and the bar of circuit breaker operating mechanism is built to analyze and calculate the fastening force and stress intensity between the bar and the ring in the process of installation.
