Ride is perceived as most comfortable when the natural frequency is in the range of 60 to 90 cycles per minute (CPM), or about 1 Hz to 1.5 Hz. When the frequency approaches 120 CPM (2 Hz), occupants perceive the ride as harsh. Consequently, the suspension of the average family sedan will have a natural frequency of about 60 to 90 CPM.

Actually, it depends from a lot of factors acting together, but the phenomenon is dominated by suspensions natural frequency, around 1-2 Hz. In attach you can find a useful paper, in my opinion.... Below is the calculation I used to determine my spring rates for auto cross racing. My target natural frequency is 2.2 in the front and 2.5 in the rear. The calculation is three steps, finding the wheel rate, find the wheel rate in series with the spring rate of the tire and using this value to calculate the natural frequency. The equations: Baja SAE is an intercollegiate design competition run by the Society of Automotive Engineers (SAE). Teams of students from universities all over the world design and build small off-road cars . The cars all have engines of the same specifications. The 2008 WPI SAE Baja Vehicle was designed to be an improvement upon the 2007 car, with all changes derived from quantitative and qualitative results from the previous summer’s competition. The main opportunities for improvement were in the drivetrain and the front and rear suspensions, so these areas were studied and then modified.

I am the project manager of a Baja SAE Team. On one of our cars we have decided that we would need heavier springs to accomodate weight added to our car. Approximately 120 pounds added at the CG. We would like to select springs that will give us the same handling dynamics as the previous setup.

Natural Frequency. Before we can examine suspension frequency, we need to introduce the concept of natural frequencies. Every [elastic] object, material, etc has a certain speed of oscillation that will occur naturally when there are zero outside forces or damping applied. Apr 29, 2018 · The natural frequency is the frequency of this oscillation, measured in hertz (Hz). This tells you how many oscillations happen per second, which depends on the properties of the spring and the mass of the ball attached to it. Plucked guitar strings, rods struck by an object and many other systems oscillate at a natural frequency.

can result in a variety of NVH concerns across a broad frequency range. Quick changes in the vehicle’s load (e.g., pedal tip-in/out) can result in an objectionable vehicle shuffle response, which is connected to the first natural frequency of the driveline and is usually in the 2 Hz – 8 Hz frequency range (depending on the selected gear) [1,2].

  • House of bianchi wikiSinhla athal katha The thing you're talking about is the sprung mass natural frequency. It is one natural frequency of a vehicle. Really just a measure of how heavily sprung a car is. High downforce open wheelers tend to migrate to very stiff setups to control to movement of the chassis (and aero elements), which in turn results in a higher natural rate.
