N2 - The transducer element is of decisive significance for the efficient and reliable initiation of micro-charges of micro-initiating explosives. The Ni-Cr bridge film transducer element boasts advantages of small size, low power consumption, and high reliability, presenting broad application prospects. In light of the unclear energy conversion law of the transducer element when the structural parameters of the current metal bridge film vary, an electro-thermal-solid multi-physics field coupling model of the metal film bridge transducer element was established. Through parametric finite element simulation analysis, the optimal structural parameters of the Ni-Cr bridge film and the ignition energy under capacitor excitation were determined. The optimal structural parameters of the Ni-Cr bridge film are: the V-shaped angle is 60, the thickness is 2. 0 μ m, the bridge width is 1000 μm, and the bridge length is 400 μm.
