Parallel Machine Tool

The dynamic characteristics of parallel 3-TPT machine tool are researched by experiment in this paper. Firstly, modal analysis principle of machine tool was analyzed in theory, and the parameters of dynamic characteristic were identified by theoretical analysis. Then vibration model of parallel machine tool was built and formed vibration system of rigid and flexible coupling for analysis. Then, the modal experiment method and steps were introduced, and the experiment parameters also were identified according to the experiment results. The result dates are showed that the result dates are validated. So the experiment method is feasible by experimental verification, which provides reference for dynamic optimal design.

The study reported in this paper deals with the development of a generalized computer-based methodology for the form synthesis and optimal design of robot manipulators. The developed computer program to implement the methodology operates in two separate modes. The first deals with the synthesis of user defined topologies and in the second mode, the designer provides only the required task, then the program will generate optimum manipulator configuration by systematic evaluation and ranking of plausible alternatives. The methodology simultaneously incorporates kinematic and dynamic synthesis as well as optimal actuation and stress analysis in an integrated design process. The procedure relies on the systematic composition of manipulator configurations from tabulated basic elements. The optimization strategy for synthesis and control utilizes a dynamic programming approach which makes it possible to select the optimum parameters in a stage-wise manner without sacrificing the interactions inherent in such highly coupled nonlinear systems.

Due to the interaction of structure and acoustic cavity, the frequency and mode shapes of the structure and acoustic cavity are different from their natural mode. To perform the dynamic characteristic of the passenger car more accurately, a structural-acoustic coupling model was established to analysis its modes. The result is benefit for the later optimal design of acoustic.

Purpose This paper aims to propose an integrated bionic optimal design system to assist engineers in bionic design tasks. In this age of ecological awareness and sustainability, engineers are increasingly applying bionics to their product designs. A recent surge of research on bionics has presented new opportunities and challenges. To deal with these challenges, an integrated design system equipped with the capabilities of conducting biologically inspired design, solving technical contradictions, optimizing design parameters and verifying design effectiveness is required. Design/methodology/approach This study proposes a two-level analysis to help decision makers conduct multi-faceted observation and assessment on conceptual bionic design. The contradictions incurred when transferring biological principals to engineering design are solved using BioTRIZ, and the conceptual design is then created. This study conducts computer-aided engineering analysis, incorporating the Taguchi method and TOPSIS method, to obtain the optimal design of bionic products. Findings The proposed design process focuses on improving the product structure instead of changing the materials, and thus, the authors are able to put the goals of saving energy, environmental protection and sustainability into practice. Practical implications Through the design and analysis processes, the authors prove that their designed bionic-fan can effectively enhance operational efficiency and reduce the aerodynamic noise. The system can provide a practical tool for engineers intending to accomplish complete designs and verifications using bionics. Originality/value Most existing design methodologies that have attempted to combine biology with engineering design have fallen short in their level of thoroughness. This study proposes a complete bionic design system by integrating the processes of bionic-inspired design, optimization and verification.
