Abstract: Virtual simulation technology is an advanced technology that has emerged in the mechanical field in recent years and has outstanding advantages. Currently, there is limited work done in China on the simulation of large-scale mechanical systems. This article, based on a brief introduction to the virtual simulation software ADAMS, applies ADAMS to model the mechanical system and simulate the dynamic characteristics of a rolling mill pressing drive, providing guidance for the simulation research of this system. Keywords: Virtual prototype; ADAMS; Dynamic simulation; Pressing system Introduction With the development of modern science and technology and the increasing requirements for the performance indicators of rolling mills, the kinematic and dynamic simulation of the rolling mill pressing system has become an important part of rolling mill system development. Considering the importance of the pressing system in the entire rolling process and the complexity of its motion, analyzing its dynamic characteristics is particularly important. This paper mainly focuses on the modeling and dynamic simulation of the rolling mill pressing drive system. 1. Virtual Prototype Technology and Application Virtual prototype technology uses numerical simulation for virtual product design and development. The parameters of the simulation model are the design parameters of the physical prototype, and the simulation model can replace the physical prototype for evaluating design parameters. Virtual prototypes are advantageous because parameter modification is convenient. Compared to physical prototypes, virtual prototyping is a "soft model," easily enabling diverse prototype designs and offering greater flexibility. Virtual prototyping technology allows for the prediction and understanding of product performance without the need for physical prototype manufacturing, eliminating the expensive physical prototype manufacturing and development process, reducing development costs, saving the long correction time required for physical prototype manufacturing and assembly, and minimizing the risk of blindly implementing unreasonable solutions. Dynamic simulation of rolling mill pressing drive based on ADAMS.
