Elements Variation in Adams Car Model and Their Effects on Vehicle Characteristics

There are different types of elements can be modified in adams models. Here are the elements and their effects on some chosen parameters.

Baseline = No Change in the double wishbone model

Modified = Element modification

1. Hardpoints

25mm LCA in +z

Results Comparison

2. Parts

Modified = Changing the lower control arm part weight from 6.5574254873 to 15 kg

dynamic ampllitude = 50

frequency 10 Hz

Effects on the Wheel load vertical force

Increasing the part weight increases slightly the force.

3. Springs

Baseline = installed length = 145.75

Modified = installed length = 120 mm

4. Bushings

Doubling the bushing stiffnesses of the upper control arm.

5. Stoppers

Baseline = Clearance 200 mm

Modified = Clearance 20 mm

For a wheel travel of 100 mm we have a spring travel around 50 mm. We can clearly see that from below graph.

6. Dampers
