1. Small semitrailer and tractor. Angle of trailer is adjustable.

2. Large semitrailer and tractor. Angle of trailer is adjustable.

3. A content authentication based mash model semitrailer watermarking algorithm was proposed.

4. The simulated results indicate that the driving efficiency of semitraiter has been enhanced by using the semitrailer axle(third axle) as a driving axle through Fuzzy Control.

5. Virtual tests manifested that running stability of the special tractor - semitrailer satisfy the design requirement.

6. Use to estimate turning radii for a typical small tractor with single semitrailer.

7. Drag onto the page to estimate turning radii for a typical large tractor with single semitrailer.

8. In the end[Sentencedict], the optimization design was conducted based on the running stability of tractor - semitrailer.

9. Use to estimate turning radii for a typical tractor with semitrailer and full trailer.

10. Use to estimate turning radii for a typical large tractor with single semitrailer.

11. Drag onto the page to estimate turning radii for a typical small tractor with single semitrailer.
