The mount in an automotive powertrain mounting system (PMS) is modelled as three-dimensional springs in its local coordinate system (LCS). The relation of the force versus the displacement of each spring is usually non-linear and is simplified as piecewise linear at five ranges in the present paper. The equation for solving displacements of the powertrain centre of gravity is presented, and an iterative algorithm is developed to obtain the displacements. The methods for estimating the displacements and the reaction forces of a mount are also proposed. The widely used strategies for the powertrain motion control under static or quasi-static loads are suggested. The calculation method is validated in designing a PMS with four mounts. The present paper adds significantly to other publications on this subject because it develops a calculation method for the design of the powertrain motion control under quasi-static loads.

“…Engine suspension designers spend time on finding the best engine mount properties that allow for a lower transmission of forces. This optimisation process can take advantage of analytical considerations and numerical simulations to evaluate the performance of an engine's suspension setup [9][10][11][12][13][14][15][16].…”

Powertrain Modal Analysis for Defining the Requirements for a Vehicle Drivability Study

et al. 2022

The powertrain of a car plays a major role in establishing the vehicle’s offered comfort due to vibrations because it is the heaviest single component installed on the chassis; therefore, when oscillating, it transmits considerable forces to the chassis, inducing unwanted vibrations. For this reason, it is important to identify some associated properties with the powertrain suspension system that describe the performance of its rigid body dynamics. In this way, we could place constraints and requirements on these quantities in order to exclude all the configurations that cause intolerable levels of vibrations, and include all the others in the analysis for further evaluation. The definition of these requirements is critical: a poor setting of requirements excludes potentially good powertrain suspension setups and includes those ones with a drivability index that is too poor. In this paper, we identify a set of quantities that show correlation with the vibration performance of the powertrain setup. A method for testing the specificity of the requirements is also shown in order to evaluate which requirements perform best when it comes to filtering engine suspension setups that provide an acceptable level of vibrations.

The development of a passenger car is a multidisciplinary task. The vehicle has to fulfill demands out of different attributes like vehicle dynamics, driveability, acoustics, thermal and heat management, safety, durability, crash and economics. One main problem is the variability of mechanical quantities responsible for the performance and customer perception of a car. To overcome this, the extension of the conventional deterministic oriented development process to a process which includes stochastic quantities is necessary. In this paper the current deterministic approach is described briefly. It is not possible to perform the extension in a single step. In a first extended version of the process the variability of material parameters is included. In further steps the formulation and solution of stochastic optimization problems for sub‐problems is necessary. Finally the complete approach should fully integrate the variability of stochastic quantities.
