Abstract Computer-aided engineering is traditionally employed to evaluate existing engine designs or very mature designs for which detailed design information exists. The analyses are performed to validate and fine tune one design rather than exploring widely differing design concepts. Thus, these analyses are often performed only after a significant commitment has been made to a particular engine design. Computer-aided engineering, however, also has the potential for providing estimates of engine performance at the very onset of the engine design cycle. Such up-front estimates may then be used to lead the design process and to allow conceptually different engine designs to be quickly assessed. For instance, up-front estimates of engine vibration and forces transmitted through engine mounts would support target cascading of engine related noise and vibration requirements at the onset of the design cycle. The objective of this paper is to review the formulation of a simulation tool to support up-front engine design for noise and vibration. This tool provides estimates of important engine noise and vibration measures based only upon a conceptual engine design. Major components of the engine model include a rigid engine block, a flexible crankshaft with hydrodynamic bearings, torsional and bending modes, and nonlinear (frequency/load dependent) engine mounts. The formulation of this model is detailed herein and sample results are reviewed for one engine design.

This article analyzes the first self-propelled floating dredging machine designed and executed by Agustín de Betancourt in 1810 to dredge the port of Kronstadt (Russia). With this objective, a study of computer-aided engineering (CAE) has been carried out using the parametric software Autodesk Inventor Professional, consisting of a static analysis using the finite element method, of the 3D model which is reliable under operating conditions. The results have shown that the system of inertia drums proposed by Betancourt manages to dissipate the tensions between the different elements, locating the highest stresses in the links of the bucket rosary, specifically at the point of contact between links. Similarly, the maximum displacements and the greatest deformations (always associated with these points of greater stress), are far from reaching the limits of breakage of the material used in its construction, as well as the safety coefficient of the invention, confirming that the mechanism was oversized, as was generally the case at the time. This analysis highlights the talent of the Spanish engineer and his mastery of mechanics, in an invention, the first of its kind worldwide, which served the Russian Empire for many years.
