Abstract: Plane four-bar linkage is widely used in mechanical products; it is a decisive factor to define the characteristics and output of crusher as the key mechanism for the model crusher. At first, expound and classify the critical parameter in theory; then ADAMS is used in parameterized modeling of plane four-bar linkage, according to the simulation optimization data of critical parameter in ADAMS, the relations among the critical parameter and influence on crusher performance are demonstrated after numerical analysis. Finally, the optimal critical values are optimized, which are applied into the design of a crusher.

Abstract: The purpose of this paper is to introduce a simplified yet efficient method to identify the critical parameter of MEMS device based on rapid computer experiments instead of expensive physical experiments. The prototype model of MEMS device is rapidly established by connecting reusable and parameterized element models based on developed element model library. Critical parameters are identified and optimal parameter assemblies are obtained using Taguchi method based on computational experiments of the prototype model. A typical MEMS device--micro resonator is used for demonstrating the design methodology. The method enables the designer to rapidly identify critical parameter of a new MEMS device in early stage of design.
