<b>Abstract</b>— <p>The results of the calculation of the period of the Chandler wobble of Mars for the set of test models of the internal structure are presented. The crust is represented by a homogeneous layer of a given thickness with a constant density. For the silicate mantle model, the distribution of density and elastic parameters was obtained using the Perple_X program. The thickness of the silicate molten layer in the mantle at the boundary with the core is taken to be 200 km. The core is believed to be composed of a mixture of iron–nickel and light elements. During the modeling, the following were varied: the density and thickness of the crust, the mineral composition and temperature of the mantle (seven mineralogical models of the mantle along three areotherms were used). The Andrade model is adopted as a working rheological model. The viscosity is given by a piecewise constant profile that varies. The internal structure models are controlled by mass, average radius, moment of inertia, Love number <i>k</i>₂ and the radius of the core. With fixed rheology and viscosity parameters the spread in the value of the Chandler period is about 1 day for different mineral compositions and temperatures of the mantle.</p>
