This chapter deals with four exemplary methods of virtual skull implants modeling. These methods combine simultaneous usage of three modeling systems: reverse engineering system, surface modeling system, and haptic modeling system, and their characteristic modeling methods and techniques. Using three different modeling systems, the authors obtain a synergy effect of the implant shape and model quality increasing. The target virtual model of the implant is always well suited to the coastline of bone lack in the skull. Additionally, time of the virtual model developed is very short compared to use of only one of the standard engineering CAx systems. The chapter describes four original methods developed by the author.

Tire Models

Recent advances in power and efficiency of computerized modeling methods has made it easier to develop accurate tire models. These newer models are now created with such accuracy that it has become easy to predict the experimental tire’s behavior and characteristics. These models are helpful with determining tire, tire-road, and tire-soil interaction properties. By creating virtual models, the overall capital for research and development can be reduced as well as replacing unavailable experimental tires for research. This research paper mainly focuses on the validation of computer generated FEA tire models which are then used for the prediction of the experimental tire’s rolling resistance, static and dynamic characteristics. Experimental data, such as rolling resistance and vertical acceleration are used in validation simulations in order to tune the virtual model to match the experimental tire’s behavior. The tire that was used for this research is a six-groove 445/50R22.5 FEA truck tire, which was constructed and validated over the course of this research.

Evaluation Of Methods

Meta-modeling is a well-known approach for capturing modeling methods and techniques. A meta-model can serve as a basis for quantitative evaluation of methods and techniques. By means of a number of formal metrics based on the meta-model, a quantitative evaluation of methods and techniques becomes possible. Existing meta-modeling languages and measurement schemes do not allow the explicit modeling of so-called multi-modeling techniques. Multi-modeling techniques are techniques that offer a coherent set of aspect modeling techniques to model different aspects of a certain phenomenon. As a consequence, existing approaches lack metrics to quantitatively assess aspects that are particular to multi-modeling techniques. In this chapter, a modeling language for modeling multi-modeling techniques is proposed as well as metrics for evaluating the coherent set of aspect modeling techniques that constitute the multi-modeling technique.

The idea of Automatic Reverse Engineering was brought forward, which reduced the requirements of modeling experience, constructed surface more efficient and especially got a more accuracy model. Its main idea was converting triangular meshes which could be easily got automatically and could express arbitrarily complex models into quadrilateral meshes.The concept of reverse engineering, reverse design process and reverse analysis were introduced in this paper, which has been used in teaching practice of mechanical design specialized curriculum, the students will be guided to apply the automatic method of reverse design to the innovation design of product by motorcycle as an example.
