Petrol and diesel engines are used in the vast majority of powered land vehicles in use throughout the world today. Competition between manufacturers to increase fuel economy and to reduce noise and chemical emissions means that engine development must be at the heart of any new motor vehicle project.

HGL Dynamics can assist motor manufacturers in their development programs by measuring vibration and noise across multiple positions on the engine, and at multiple locations within the vehicle cabin. Our high channel capacity gives us the capability to fully instrument a vehicle for simultaneous recording of up to 128 channels with a single Hawk unit.

Our dynamic vibration and noise signals are then analysed against time or engine speed, in the time domain or the frequency domain. Features dependent on engine speed can be compared against the natural modes of the vehicle. In this way, motor manufacturers can quickly associate cabin vibration problems with their source in the engine or chassis.
