“Advanced Topics” is Part 8 of a ten part presentation series "Automotive Dynamics and Design". The intent is to form a comprehensive series of lectures providing instruction in the design of automobiles from both a practical and a stylistic viewpoint. The ten segments constitute the core (reading assignments, homework, and test material not included) of a class to be given over a period of about twelve weeks. The ten course segments are: 1) "Automotive Dynamics and Design" 2) "Longitudinal Dynamics" 3) "Lateral Dynamics" 4) "Vertical Dynamics" 5) "Mass Properties Analysis and Control" 6) "Tire Behavior" 7) "Aerodynamics" 8) "Advanced Topics" 9) "Design (Styling)" 10) "Summary" Part 1 is essentially an introduction to, and a syllabus for, the course of study. Part 2 constitutes a study of automotive acceleration, braking, and crash deceleration. Part 3 constitutes a study of oversteer, understeer, directional stability, rollover, lateral acceleration: transient and steady state. Part 4 constitutes a study of springing, damping, shock attenuation, road contact, road vibration transmissibility, ride motions. Part 5 constitutes a study of the ten mass properties equations, the ten mass properties uncertainty equations, standard deviation, normal distribution, regression analysis, coefficient of determination, correlation, degrees of freedom, total weight estimation, unsprung weight estimation, sprung weight estimation, estimation of the total weight c.g., estimation of the unsprung weight c.g., estimation of the sprung weight c.g., estimation of the total mass moments of inertia, estimation of the unsprung mass moments of inertia, estimation of the sprung mass moments of inertia, estimation of the total products of inertia, estimation of the sprung roll moment of inertia. Part 6 constitutes a study of friction vs. traction, normal load vs. deflection, normal load vs. contact area, load capacity, vertical stiffness, lateral traction, longitudinal traction, %Slip, Slip Angle, Traction Ellipse, rolling resistance, temperature effects, speed effects. Part 7 constitutes a study of Navier-Stokes Equations, dimensionless indicators (Reynolds Number, Mach Number), streamlines, Bernoulli’s Equation, drag, lift, boundary layer, separation, wake, vortices, center of pressure, aerodynamic stability, wings, fences, spoilers. Part 8 constitutes a study of camber, caster, toe in/out, scrub, kingpin angle, scrub radius, effective spring rate, roll stiffness, suspension geometry, roll axis, steering geometry, turn centers, geared and equivalent gearless systems, products of inertia, gyroscopic reactions, fuel economy, standing wave, hydroplaning. Part 9 introduces the concept of Design (a.k.a. Styling), Design Schools, Design Practitioners, Design Process, Exterior Design, Interior Design. Part 10 deals with the business and manufacturing aspects of automotive endeavors: business plan (product, market, cash flow, P&L, capitalization, ROI, etc.), profit and loss statements, break-even analysis, in-house or subcontract decisions, plant location and layout, jigs and fixtures, equipment, supply and inventory, customer service & relations strategy.
