Abstract
The loading mechanism is one of the most important parts of a tester for micromechanical
properties, by which specimens can be loaded and deformed on both
the microscopic scale and one millimetre scale with a monolithic two-stage
flexure- hinged structure. The mechanical characteristics of the two-stage
loading mechanism are analyzed separately. On the basis of this analysis, the
problems in the optimal structure design about the first and second stages are
discussed, and the optimal models are presented respectively according to the
mechanism’s practical application requirements. The genetic algorithm and
fuzzy optimization methods were used to solve the optimization problems in the
desig
