MAN Truck & Bus Interview Questions, Process, and Tips

Resonance is the phenomenon of an object vibrating at its natural frequency due to the influence of an external force.

• Resonance occurs when an external force is applied to an object at or near its natural frequency.

• The amplitude of the vibration increases as the frequency of the external force approaches the natural frequency of the object.

• Examples of resonance include a tuning fork vibrating when struck, a wine glass ...read more

Resonance can be prevented by changing the natural frequency of the system or by damping the system.

• Change the stiffness or mass of the system

• Add damping to the system

• Use tuned mass dampers to reduce vibrations

• Avoid designing structures with natural frequencies close to external excitation frequencies

EV HV architecture consists of battery, motor, inverter, and controller.

• EV HV architecture is responsible for converting DC power from the battery to AC power for the motor.

• Major components include battery, motor, inverter, and controller.

• Battery stores energy and provides power to the motor.

• Motor converts electrical energy into mechanical energy to drive the wheels.

• Inverter converts DC power from the battery to AC pow...read more
