With the increasing demands of the diversified expandable shelter and its reliability of structure in modern society, the requirements of the transmission mechanism that affects the deploying and withdrawing of shelter are also getting higher. At present, there are few studies on the mechanical characteristics of its contacts. In this paper, the contact model of the expandable mechanism of shelter under the elastohydrodynamic lubrication (EHL) condition is established based on the multigrid method. The algorithm is implemented on the platform of MATLAB, and effects of the load, velocity and lubricant viscosity on the contact characteristics of the expandable mechanism are analysed. The results show that the performances can be improved by reducing the external load and increasing properly the velocity and lubricant viscosity. The research in this paper can also provide theoretical reference for design of the expandable mechanism of shelter.
