Course details

The best powertrain mounting design for ICE vehicles and EVs differs due to distinct vibration sources and frequencies. For ICE vehicles, a traditional 3-point mounting system is commonly used, focusing on low-frequency dynamic stiffness to reduce vibration. In contrast, EVs benefit from a double isolation mounting system, which connects the powertrain to an auxiliary mass (subframe/cradle) via mounts, and then suspends it to the vehicle body via subframe bushes. This design addresses high-frequency resonance issues (600-1000 Hz) due to motor excitation frequency. Proper selection of mount stiffness, modal alignment, and material selection are crucial to avoid resonance and improve vibration isolation. Simulation-based design, transfer path analysis, and parametric studies can help optimize the powertrain mounting system for both ICE and EV applications.

Questions and Answers

A: A tracks units and the frequency ratio. Hz is converted properly and the tributary mass is used. B skips the 0.7 factor and inflates isolation risk. C drops three orders by mixing N/mm and kN/mm and also grabs the wrong mass basis. D adds a safety factor where it hurts isolation and ignores the frequency target.

A: A lines up with the 600–1000 Hz content the double isolation is meant to kill. Stiff bushes short-circuit that path. B and C sit in low-frequency space where mounts still dominate. D is governed by brackets and hard stops, not bush tuning.

A: A matches oil splash and ozone at elevated temperature. B cracks fast in oil and ozone despite nice damping. C survives ozone but swells in oil and drifts stiffness. D handles heat but tears and walks under mount shear.

A: A creates the extra isolation stage needed for motor excitation bands. B runs out of attenuation at high frequency. C trades NVH for durability risk fast. D helps low frequency shake but doesn't touch the motor whine band.
