Abstract: Recent radio pulsar observations have shown that some pulsars have interesting long term period variations which can be approximated by a sum of periodic functions. Such periodicities could be explained as free precession of a pulsar or as evidence of a planetary system around it (like PSR 1257+12). We present pulsar timing simulations of three dynamic models of precessing neutron star: homogeneous rigid body, Zhukovski-Volterra gyrostat (rigid body carrying rotator inside) and rigid mantle with a triaxial ellipsoidal cavity filled with inviscid fluid.
