The digital twin is considered a new and promising concept whose added value is seen mainly in end applications. However, the benefit of considering the digital twin application since the early development of the system seems not to be stressed enough. The ability to choose system components, methods, and tools can have a symbiotic effect during system integration. This work describes a development process of a Stewart platform digital twin based on its multibody simulation model created in Matlab/Simulink. Although the multibody simulation model is useful in the design phase, after adjustments and verification, it can also be reused as a virtual entity of the digital twin. This integration is enabled by the methods, tools, and system architecture selected for the purpose of including a digital twin. This is considered to be the main contribution of this paper to emerging methodologies for the development of mechatronic systems and its digital twins. However, practical integration comes with challenges that are related to the model fidelity and synchronisation of the virtual and physical entities and are important to overcome in order to employ the system in the real applications.

“…The Stewart platform is a parallel mechanism consisting of six retractable legs connecting a fixed abutment and a moving platform, which can realize the control of the platform's arbitrary position in three-dimensional space [1]. The Stewart platform was initially invented by Gough in 1947 for detecting the wear and tear of tires, and was later proposed by Stewart in 1965 to be applied to flight simulators, thus attracting much attention and research [2,3].…”

The ability of Stewart platform to resist deformation is an important target for designing and optimizing the platform, and studying the variation rule of stiffness of Stewart platform under different loads can help us to understand the dynamic characteristics of the platform, guide the design and control of the platform, and improve the performance and stability of the platform. The purpose of this paper is to change the law of stiffness variation and influence factors of Stewart platform under different loads, aiming to study the change of stiffness of Stewart platform under different loads as well as the influence factors, and the influence of stiffness change on the performance and stability of the platform. Firstly, using MATLAB software, the kinematic and mechanical model of Stewart platform was established, the analytical expression of the stiffness matrix of the platform was deduced, and the stiffness characteristics and stiffness singularity of the platform were analyzed. Then, using ADAMS software, the dynamic simulation model of the Stewart platform was established, and the stiffness of the platform was simulated and analyzed. The results show that the stiffness of the Stewart platform will appear singularity or sudden change under some special positions or loads, which should be avoided as much as possible so as not to affect the performance and stability of the platform. There is a certain correlation between the dynamic and static stiffness, but it is also affected by the nonlinearity of the structure, damping, coupling and other factors.
