This document outlines the general requirements for modeling a driveline system connecting an engine to a machine. It lists tools and software needed like MATLAB and CAD software. It also lists engineering specifications required like the engine and driveline designs, material properties, operating speeds, and torque variation methods. Manufacturing requirements include assembly alignment verification. The expected outcomes are a report locating the system's natural frequencies and critical speeds, and identifying vibration nodes and structural failure modes.

2. Tools and software to purchase
• MATLAB software and license
• 3D CAD design software (Inventor, Catia, Solidworks, etc.)
Engineering
• The driveline design drawings or CAD
• The engine design drawing for Crankshaft and piston geometry
• The engine engineering specs (connecting rod length, number of cylinders, firing order,
etc.)
• The engagement sequence and type of the driveline with the engine (permanent,
tapered pins, gears contact…)
• The elastic properties of the driveline components and the engine (Stiffness, polar
inertia, mass inertia, center of gravity, shear modulus)
• Drivetrain materials category (pure metal, alloys, mix….)
• Machine operating speed range
• The method of speed and torque variation (smooth ramping, instantaneous change
through gear box, high speed disengagement,…)
• Vibration suppression hardware (cushions, rubber, springs, sway bars etc.)
Manufacturing
• Verifying the couplers alignment relative to the driveline
• tightening the assemblies’ bolts as rated
• verifying the flex plates degrees of freedom as rated
Outcomes
• Locating the system’s natural frequencies (report)
• Defining the machine’s critical speeds
• Locating the vibrational nodes along the driveline
• Graphical representation of structural failure modes
