  • This study is related to the development of a design automation system for the construction design phase of steel structures. The system intended for beam splice friction connections using high-strength bolts. The standard design method and standardization principles that are suggested in the design manual for standard connections using high-strength bolts published by the Korean Society of Steel Construction(KSSC) were reviewed. A structural analysis algorithm was formulated from the review. A design automation system that can automatically calculate the structural design of connections and automatically generate the connection model without separate inputs was developed. To verify the validity of the developed system, its results were compared with the date in the table for the connection design in the Design Manual. The development system was also applied to the sample model. Then the structural design results were compared with the properties of the connection models and drawings created from the results.

  • The speed change performance of transmissions has become a serious issue because of the increase in the inertia moment that has accompanied increases in engine output and transmission size. Therefore, it is necessary to develop better wear resistant friction materials. In this study, an appropriate sintered friction component for the synchronizer ring of a diesel manual transmission was developed, and its bonding characteristics were analyzed. That is, a process for bonding an Fe-based base material and Cu-based sintered friction material was developed. BSE and EDX analyses of this bonding layer were conducted, along with a shear strength test, to determine the bonding characteristics.
