Abstract: Testing instruments play a vital role in the industrial sector, ensuring product quality meets standards. The function of mechanical transmission systems in testing instruments lies in transmitting motion and power. This paper proposes an integrated mechanical transmission functional feature model that transmits both motion and power, along with its encoding method. It constructs a transmission knowledge base integrating transmission functions and mechanism knowledge, establishes four basic transmission functional matrices-motion-motion, power-motion, motion-power, and power-motion, and integrates them into a unified transmission functional matrix. Based on this, it proposes an integrated transmission functional matrix for transmitting both motion and power. motion-to-motion, power-to-power, and power-to-motion transmission functional matrices. These are integrated into a unified transmission functional matrix. Based on this framework, a mechanical transmission design methodology for testing instruments is proposed, utilizing the transmission functional matrix to integrate motion and power transmission. The method is illustrated with an example of a liquid chromatograph testing instrument, which confirms that the method is helpful for the design of the mechanical transmission system of the instrument.
