A modelling and calculation method for obtaining the displacements of the powertrain's centre of gravity (CG) and mounts in a powertrain mounting system (PMS) including the torque struts under a static or quasi-static load is presented. A new mount model that is modelled as three-dimensional (3D) springs with both a translational stiffness along each axis of its local coordinate system (LCS) and a rotational stiffness around each axis of its LCS is presented. Also a torque strut is a generic construction and is regarded as a massless rigid body with a mount at each of its two ends.
The equation and the solution method for estimating the displacements of the powertrain's CG and the mounts under a quasi-static load are developed when torque struts exist in a PMS. An example is given of the calculation and comparison of the displacements of the powertrain's CG and mounts in a generic PMS including a torque strut using both the method proposed in this paper and the conventional method published in the referenced papers.
