ME 370

Fall 2016

Computer Project

Due: in class Friday Dec. 9, 2016

A vehicle can be modeled with the simplified model in the figure. Mv, Jv, Mw, Kc, and

Kt represent the mass of the vehicle, its moment of inertia, the mass of each axle, the

stiffness of each axle, and the stiffness of each tire, respectively.

Mv=1500kg, Jv=1000kgm2, Mw=20kg, kc=200kN/m, kt=350kN/m, l1=2m, l2=2.5m

Determine the following:

1.

The equation of motion

2.

The natural frequencies and mode shapes

3.

The automobile?s vertical and pitching motions as a function of time when the

road creates a displacement of 0.01cost m for each tire, where 100 rad/s.

Students work as a team to complete the computer project. Each team only needs to turn

in one report. Your report should include:

1.

Listing of the computer program you developed

2.

3.

Plots of the vehicle?s vertical and pitching motions as function of time

4.

x3 kc kc x1 x2

Mw Mw

kt kt 11 12
