But, undercut technology may deteriorate the stresss concentration. In order to improve the situation, for a crank throw of a given ductile iron crankshaft, finite element analysis is conducted. The analysis result is optimized and related fatigue calculation is carried out. A compare between calculation and test results is performed and compared results show that conculation result is reliable. Therefore a good undercut structure is found and the reliability of crankshaft is improved.

In this thesis, the characteristics of software agents and their behavior modes are analyzed to find the influences of characteristics on behavior modes and to infer the master-slave and provider-requestor relationships among agents. Testing orders could be founded by relationships between agents. After the analysis of reciprocal effects among characteristics, we proposed that in the testing on a single agent, the autonomy should be tested first, the mobility is tested then, and the collaboration is tested finally. The testing of learning is incorporated into the testing of autonomy. A rolling-style testing method of software agents is proposed. Our testing method takes the IBM Aglets software agent language as an example, and develops testing tools under the IBM Aglets execution environment.
