Tiivistelmä
Global changes in the business environment of machinery industry have dispersed the functions of the companies such as product development functions and functions subjected to it. No longer is structural analysis conducted under a single product development organizations, instead the structural analysis team or organization may be dispersed globally. This dispersion of the structural analysis organization has produced uncertainty and complexity to the structural analysis process, which in turn has created a need to harmonize and automate the structural analysis process.
To harmonize and automate the process, an analysis package consisting of analysis instructions and tools was decided to be created. To create this analysis package a framework following the principles of an action research was established to structure the project and guide the analysis and interpretation of theory and its use in practice. The goals of this thesis can be summarized as follows: What are the requirements of the analysis package? What kind of package can be created for the needs of the case-company?
By analyzing the current state of the product development and structural analysis and their challenges, by presenting the main standards affecting the instructions and by analyzing simulation-based structural analysis an understanding of the themes of this thesis was established as was the requirements for the analysis package. The requirements for the analysis tools were categorized to structural analysis process requirements and FE-analysis workflow requirements. The requirements for the analysis instructions were categorized to structural analysis process requirements and instructional design requirements, which determine the characteristic requirements of instructions.
The selection of analysis tools was done by conducting a survey of suitable Ansys-extension tools, which were tested and evaluated against the requirements. 7 most suitable analysis tools in terms of requirements were selected for the analysis package. These extension tools offer features for pre- and post-processing and methods for interpretation of results. Instructions, on the other hand, were created for 4 FE-analysis cases: 1) Strength analysis of a bolted joint, 2) Lifting point analysis 3) Retrieval device analysis, 4) Elastic-plastic analysis. All in all, this analysis package provides a practical approach to answer to the challenges the modern product development environment opposes and an approach to develop the structural analysis process.
