Development of sliding bearing materials started late in China.
In order to meet the development requirements of automobile, the performances of bushing materials are required that the bushing sleeve fit the cycle.

However their works concentrate on structural stiffness of wing structure on different wing materials and techniques to determine flutter.
Discussion From the tensile test conducted on the flat plate composite wing, the specimen possessed the behaviors of composite materials since there is no indication of plastic region in Fig. 8.
The material mechanical properties are as shown in Table 1.

Brief principles of crankshaft fillet rolling Fig.1 Crankshaft Fillet Rolling Strengthening diagram As shown in Figure 1, as the crankshaft fillet rolling, the crankshaft rotates around its spindle, Rolling head and Support head are mounted on the rolling clamp body, the rolling clamp body clamps the crankshaft and pressurizes to the predetermined pressure by the pressurized cylinder, The active rotation of the crankshaft journal forms the journal friction between the rolling wheel and journal and drives the rolling wheel to rotate, rolling the crankshaft journal.
The pressure makes the surface of plastic deformed through the rolling wheel, then there will be residual compressive stress, which will exist permanently. significantly increasing the strength of the crankshaft journal, significantly improve the strength of the crankshaft journal.
Because the Q235 steel has good strength and stiffness, which could meet the materials requirements.
Conclusion From the above model improvement program and analysis results, we can see the weight of the rolling arm is significantly reduced by two optimization, the stress distribution is more reasonable when the rolling is in a clamping state, not only saves materials, makes full use of the strength characteristics of the materials, but also optimizes the lightweight of the rolling arm, provides a theoretical basis for the optimization of the single degree of freedom crankshaft fillet rolling machine clamp structure.
