How is chassis stiffness measured
WebA Frequency Response Function (or FRF), in experimental modal analysis is shown in Figure 1: is a frequency based measurement function. used to identify the resonant frequencies, damping and mode shapes of a physical structure. sometimes referred to a “transfer function” between the input and output.

Web13 nov. 2000 · This paper looks at the fundamental issues surrounding chassis stiffness. It discusses why a chassis should be stiff, what increasing the chassis stiffness does to … WebThe chassis feels balanced but isn't as stiff as something like a 3-series. The car is eager to rotate, aided by the near 50-50 weight distribution and the low center of gravity, but you're always aware of the weight of the car, partly because the stock suspension isn't up to German or JDM sports sedan standards.
WebFrom this, you will be able to calculate the Young modulus for the material of the wire. The Young modulus is given by the slope of your graph, and is a measure of the stiffness of the material – for the steeper the gradient, the stiffer (harder to extend) the material. Collect these to start. G clamp, 10 cm jaw. 2 wooden blocks WebGenerally speaking, car manufacturers have an overall total chassis torsional stiffness somewhere above 15-20,000 N*m/degree.
