An improved metamorphosis-based scheme of configuration synthesis for feed mechanism

Abstract

In this work, the principle of metamorphic mechanism is optimized for product design based on the variable topological structures. A metamorphic element consisting of kinematic pair and kinematic size is proposed firstly. A new configuration synthesis strategy for feed mechanism is performed in view of the translocation, inversion and duplication variation methods. The metamorphic elements are obtained by means of the decomposing the source metamorphic mechanism. A novelty configuration scheme based on constraint variation features is established by the solution of constraint relationship of metamorphic elements, and three kinds of configurations are synthesized. The comparisons of kinematic performances between source mechanism and new mechanism configurations are carried out using kinematic simulation. Results demonstrate that proposed strategy can synthesize successfully multiple types of the metamorphic mechanisms to meet the demands of functional targets.

Design of initial configuration method of peripheral chip based on DSP+FPGA board

“…C language timing control is simple, instruction writing expression is clear. The software code of the FPGA module is implemented in the software development tool ISE14.7 with the Hardware Description Language (VHSIC Hardware Description Language, hereinafter referred to as VHDL) [11] . VHDL is slow to compile, but highly integrated and has strong logic implementation capabilities.…”
