Based on the strain energy model presented by Sun-Zhang and the energy conversion and energy conservation,a new semicontinuum model is presented to calculate the nature frequency of a nanoscaled clamped-clamped silicon beam.

This article,with the study on transmissibility characteristics of vibration-isolating device viewed as a continuum,analysed characteristics of vibration-isolating device under the modles of discrete elastic components,poles and beams,so as to provide scientific evidence for resolving vibration problems of numerical-control machine tools.

In the process of designing the monolithic compliant mechanism via multi-objective topology optimization of continuum,the elasticity modulus and external loads are treated as random variables, and so are the strain energy and the mutual potential energy acting as the objective function.
