Exploratory study of mechanical kinematic innovation design based on gene recombination operation

摘要

This paper analyzes the influencing factor of motion output of the inspired mechanism under the premise that the motion input is invariant. These factors are respectively expressed as kinematic pair chromosome number, kinematic pair feature gene and distance relationship vector gene by virtue of several concepts and principles in genetics, and then they are encoded. Mechanism chromosome model is established, which is constituted by mechanism chromosome relationship graph and mechanism chromosome matrix. Three kinematic pair chromosome gene recombination operations on mechanism chromosome model (dominance, translocation and metastasis), are proposed by using meiosis and chromosome variance in genetics for reference. Finally the paper takes shaper as the original mechanism and acquires its inspired mechanism, which proves the convenience and practicality of the methods.
