Abstract and Keywords

Abstract: The operation of mass transfer equipment at high speeds and frequencies results in the generation of significant heat, which can lead to thermal deformation of components and, consequently, a notable decline in the precision of the mass transfer process. It is of great importance to develop a reasonable model of the thermal error of mass transfer equipment and to implement a thermal error compensation strategy in order to guarantee the transfer precision. This paper presents the research progress on thermal error compensation technology for high-speed feeding mechanisms. It provides an overview of the current research landscape, both domestically and internationally, with a focus on three key areas: thermal characteristic analysis and modelling of high-speed mechanisms, thermal error modelling technology, and thermal error modelling and compensation of high-speed feeding mechanisms. Firstly, the thermal characteristics of linear motion mechanisms are introduced. Secondly, the temperature measurement, thermal error measurement, optimal selection of temperature measurement points, and thermal error modelling method in the process of thermal error modelling are systematically elaborated. Finally, the research on thermal error compensation of mass transfer equipment is summarized and outlined to provide reference for related technical research.

Keywords: mass transfer equipment; high-speed feeding mechanism; linear motor; thermal error mechanism; thermal error compensation
