Introduction to HyperWorks for linear static and non linear quasi static analyses within a project of product development
1 like2,661 views
The suite HyperWorks (HW) was introduced in a course of master degree in Mechanical Engineering. The course titled “Design of Production Processes” has the aim to develop a market-pull product in a set of steps beginning with a perception of a market opportunity and ending in production, sale and delivery activities. HW was used for linear static and non linear quasi static analyses to correctly size the different parts which make up the investigated product. The lessons were organized starting from a general overview on Finite Element Analyses, followed by an introduction to HW interface and, finally, the steps necessary to set-up and to analyze the results of different types of simulation were described. Furthermore, topology optimization of particular sub-components were performed by Inspire. Speakers Francesco Gagliardi, University of Calabria

DesignandProductionPlanning The aim of the course is the design and the development of a new product, by implementing a set of methods aimed at bringing the following functions of an enterprise: 1) Design 2) Manufacturing 3) Marketing Each enterprise function is considered like independent and not integrated. Even if the design of a new product is a complex task, it did not require a revision process, due to the low enterprise interaction.

- 25. Conclusions A first experience on teaching, at university level, the basic concepts of HyperMesh Desktop was presented The aim of the proposed activity was to provide a tool which the students could use for finding optimized model specifications Simple linear static, normal modes and buckling analyses were carried out from each group The code interface and the different steps to follow for properly setting simulations was not easy to introduce and to explain in the course The most motivated students exceeded the initial settings by proposing numerical models with growing difficulties For the future years, the idea is to dedicate more hours to the code learning (i.e. OptiStruct Optimization will be introduced over the next academic year) 2625/
