Active vibration control of composite structure by PZT and PVDF concludes that, in the first mode i.e., 21Hz at 160V, for 0.133N force, % of reduction in vibration by PZT is 18%. For the second mode i.e., 106.8Hz at 196V, for 0.035N, %of reduction in vibration by PZT is 48%. As the voltage increases, there will be more control in vibration.
In the first mode i.e., 23.5Hz at 150V, for 0.1N, %of reduction in vibration by PVDF is 3% and for the second mode i.e., 106.5Hz at 370V, for 0.033N, % of reduction in vibration by PVDF is 7%. As the voltage increases there is a reduction in vibration.
PVDF which is light weight in nature, its stiffness is less compared to PZT. In this case voltage is varied. In future work, multiple PVDF’s can utilize for the vibration control by increasing the voltage as well as force.
Vibration Analysis, Emerson Makes it Easy for YouDieter Charle
One of the most powerful tools to deploy reliability centered maintenance are portable vibration measurements.

Design and simulation result of various spiral antennas.
Spiral antennas belong to the class of "frequency independent" antennas; these antennas are characterized as having a very large bandwidth. Spiral antennas are travelling wave structures and are well-known for their wideband performance. A bandwidth of 5:1 or 10:1 is easily obtained and a stable input impedance is achieved through a self-complementary geometry. This wideband characteristic of the spiral antenna makes it an attractive choice where a single antenna is required to send / receive over multiple channels. Spiral antennas are usually circularly polarized. The spiral antenna's radiation pattern typically has a peak radiation direction perpendicular to the plane of the spiral (broadside radiation). The Half-Power Beamwidth (HPBW) is approximately 70-90 degrees.
Spiral antennas are widely used in the defense industry for sensing applications, where very wideband antennas that do not take up much space are needed. Spiral antenna arrays are used in military aircraft in the 1-18 GHz range. Other applications of spiral antennas include GPS, where it is advantageous to have RHCP (right hand circularly polarized) antennas.
There are several kind of spiral antennas . An Archimedean spiral made of two equal lengths of coaxial cable seems to be the easiest circularly polarized antenna to make that'll cover a broad range.

Nonlinear static simulation of automotive bumper of a passenger car in low sp...eSAT Journals
Abstract Bumpers are important structural components of vehicles in terms of safety, static strength, and styling. This work describes various aspects of the nonlinear static FEA of vehicle front bumpers using the commercial software Ls-Dyna, and the correlation with physical tests. The basic concepts, procedures and techniques of nonlinear FEA are presented. The effects of various aspects of nonlinear simulations like numerical integration, contact parameters, non-conformance of the mesh and material law are studied. A nodally integrated element formulation for plates is proposed for analysis, and the formulation is implemented in Ls-Dyna using the UEL user subroutine. Numerical tests are carried out on the new element. Suggestions are proposed in simulation to improve the correlation of CAE results with physical test. Keywords: CATIA V5, HYPERMESH v11, EPS, Ls-Dyna, ASTM D880.

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.

An engineer working for Northrop Grumman Systems Corporation Marine Systems (NGSC-MS) was given a project to improve their teams’ current NASTRAN results post-processing workflow by writing a script to automate the task. They reached out to Altair for collaboration and Altair engineers were able to quickly determine that Altair’s mathematical modeling environment – “Altair Compose” – would be the ideal solution due to its ability to read, manipulate, and write NASTRAN results. Also, the Open Matrix Language is a scripting language that is familiar to the engineering community. Given sample NASTRAN results and requirements Altair engineers provided a “template” script. The NGSC-MS team was able to quickly understand and modify the script to their goals. The custom results were then viewable in HyperView as a contour plot, which saved a considerable amount of time during post-processing and documentation workflows.
Designing for Sustainability: Altair's Customer StoryAltair
Bush Bohlman was required to perform the structural analysis and timber design for the British Columbia Institute of Technology, (BCIT), student plaza, a pedestrian and public transport user gateway for the institute. The structure needed to establish a strong campus identity with a biophilic design and demonstrable support for sustainable building practices while ensuring structural safety according to local design codes. The hybrid mass timber structure consists of a Cross-Laminated Timber (CLT) canopy, CLT columns, and steel columns. By using S-TIMBER, the engineers were able to simulate the complex two-way bending behavior of the cantilevering roof panels and asymmetrical column layout. Having the model in S-TIMBER allowed for changes to be analyzed and re-designed, without the need to manually design individual timber and steel elements. S-TIMBER's design reports presented the design calculations concisely, yet transparently, for faster and easier reviews.

Lead time reduction in CAE: Automated FEM Description ReportAltair
For each deliverable FE-Model a FEM description report needs to be generated. Since this document contains always the same type of information, it is an ideal candidate to automate the creation of this report. Based on the Hyper Report Tool from Altair, RUAG Space and Altair developed a tool to automatically generate the FEM Description Report. The tool requires the HyperMesh data base and the output files from FEM checks as inputs. Together with the tool template, guidelines are provided on how the data base needs to be set up, such that the report can be created automatically. The main structure of the FEM Description Report is dependent on the assembly structure of the HM data base.
Car makers have to reduce consumption of vehicles and so, are continually looking for solutions to lighten components. For powertrain, components generally mean screwed assembly, contact and fitting interfaces, with different kind of loading to take into account (static and dynamic). Hence, we decided to apply with Altair assistance, a process of topology optimization on an assembly of gearbox housing in order to check its feasibility and efficiency. Several steps had to be solved from exhaustive identification of all mechanical constraints to execution of large models with Optistruct. By the end, the process has been defined and implemented on an existing gearbox and will be soon apply on the next one to design.

The Team H2politO: vehicles for low consumption competitions using HyperWorks Altair
The Team H2politO is a group of students of the Politecnico di Torino. The student’s background and profiles are very diverse, everyone comes from a different discipline of engineering and together they compose a complete Team. The disciplines range from Automotive and Mechanical to Electronics, Aerospace, Energy, Mathematics, Computer Science, Mechatronics, Management, Cinema and Media and Industrial Design. The Team mission is to shape a new generation of engineers, leaders in their fields, who represent the educational excellence in regard of each of their competencies.
The results of Team passion and hard work are three low-energy consumption vehicles completely designed and made by the Team: IDRA - hydrogen powered prototype; XAM – bioethanol powered parallel hybrid urban concept; XAM 2.0 –EREV city vehicle.
The main goal is to take part and win in Shell Eco-marathon, a competition that every year involves more than one hundreds of students teams arriving from all over Europe. Especially we would like to spread the Shell Eco-marathon values through ours, combining the sustainable development with a vehicle that uses the least possible amount of energy.
H2politO is a different, innovative and somehow unique project, is not just a Team but something more: it is a new type of conceiving educational, professional and personal growth. Team members aim at being perceived as an experimental laboratory where competences, capabilities and potentialities of future’s engineers are fostered. Students strive to become not only solid and advanced technical experts but, equally important, down-to-earth managers having excellent communication, leadership and teamwork skills.
Practical and hands-on experiences are doubtlessly a complementary and enriching form of educational path where it is very important the use of simulation software like HyperWorks. Team members have a real opportunity to lead their educational path by building and crafting their own thesis. Final papers are indeed part of a cluster of thesis which combines all the technological and organizational areas of development H2politO has envisioned and embraced.
The Team believes in hard work as the basis of future success. Students crave for continuously improving and strive for exceeding expectations by nurturing the team spirit in order to create those synergies able to add value to individual performances and capabilities. As a consequence, passion and team-spirit are really the foundation of H2politO values.
