Design method of a vibration-isolated single-molecule electrical measurement device

Abstract

The invention provides a design method for a unimolecular electrical measurement apparatus adopting a vibration isolation structure. The method comprises the following steps of 1) designing a geometric model in a computer; 2) filling the geometric model with a material; 3) performing grid division on the geometric model; 4) setting a physical field, a boundary condition and parameters; 5) selecting a solver for performing calculation; and 6) performing an actual test for verifying the correctness of a computer simulation result. According to the design method for the unimolecular electrical measurement apparatus adopting the vibration isolation structure, provided by the invention, the design complexity is lowered, and the design cycle is greatly shortened; and the method is suitable for all small-sized and high-performance-requirement suspended vibration isolation system design, especially vibration isolation system design of the unimolecular electrical measurement apparatus.
