In the present work, the numerical analysis of the structure of a prototype of a SAE BAJA type automobile chassis is developed. Within the proposal of the model, factors that become important when implementing it are considered, these factors are: driver safety, sufficient spaces for vehicle components, among other basic points. Likewise, the model is subjected to different tests established by the Society of Automotive Engineers (SAE), tests such as: Front impact, rear impact, side impact, overturn, landing tests for front jump and rear jump; the conditions to which these tests are subjected are extracted from articles (tests) and applied in the appropriate areas to have the most accurate and close to reality results. The analysis is carried out with different materials and profiles used for structural members, in this way the appropriate configuration of the profiles and materials is also obtained. Due to the satisfactory parameters obtained, a fairly efficient model is obtained, this has an impact on the necessary safety for the driver, basically, because the system has low deformations in the materials and withstands relatively high stresses.

Abstract: The car's chassis is also called a structure that locates and mounts all the vehicle's components. It also creates a secure environment for the occupants. The chassis will provide torsional and flexural rigidity to the vehicle that makes the chassis one of the most crucial elements of the vehicle. Therefore, the front impact, rear impact, side impact, front torsional, rear torsional, vertical bending, lateral bending analyses were performed. The contribution of chassis is not limited to supporting the vehicle’s component, but it extends to providing better performance and aesthetics. Therefore, the design of the car chassis must be done accordingly. The current paper deals with the study of the design and analysis of the race car. The deformation, stress, and Factor of safety were considered as the evaluation parameters which were obtained by Finite Element Analysis (FEA) in Ansys software. To design the chassis, the SolidWorks software was utilized. Keywords: Car Chassis, Design, FEA, Material Comparison.

Object The purpose of this study was to evaluate how currently used helmets would perform for winter play activities, such as tobogganing. In Canada and northern parts of the US, the advent of winter is followed by an increase in visits to hospital emergency departments by young children presenting with head injuries resulting from winter activities. Sliding, skating, skiing, and snowboarding all involve risks of head injury from situations such as falling on ice or sliding into stationary objects. This study compared the protective characteristics of helmets used by young children (< 7 years of age) participating in winter recreational activities. Methods Ice hockey, alpine ski, and bicycling helmets were impacted at 2.0, 4.0, 6.0, and 8.0 m/second at the front and side impact location by using a monorail drop rig. Results The results for the front impact showed that the ice hockey helmet protected the child significantly better at 2 and 4 m/second when considering both linear and angular peak acceleration. The bicycle helmet performed significantly better than the other 2 helmets at 8 m/second for the front location and only angularly for the side impacts. Conclusions Depending on the impact velocity of the hazard, the type of helmet significantly affected the risk of brain injury.

The Impact

Occupants safety is one of the most important criteria in car design. Due to the less space between occupant and side door, the scope of energy absorption is less. Hence in a case of side impact, the strength of side door is plays crucial role. A side intrusion beam is mount inside the side door and is also called side impact beam. During side impact, side intrusion beam gets deformed and it absorb the highest amount of energy compare to others parts of side door. And also for smooth bending during the impact, nearly equal amount of force should absorb during the whole bending process. So design of side intrusion beam is important part of vehicle door design. The various parameters of intrusion beam like, material of intrusion beam, shape of intrusion beam, dimensions, mounting of beam inside the door etc. are affected on the strength of side door. In present work using finite elements analysis the effect of important parameters of hollow circular cross section side intrusion beam on Crash Force Efficiency (CFE) is studied. The ABAQUS software is used to perform various finite element simulation. In the first part of this work most influential parameter is determine by Design of Experiments and ANOVA analysis, in a second part of this work relative effect of this influential parameter on crashworthiness of side intrusion beam is studied.

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

<p><em>In this study, I have collected and summarized the functional aspects of a literary prize, contest, and rating, which indicate their affiliation with the marketing complex of the publishing house for the first time. For this purpose, I have analyzed and summarized the common concepts of the functioning of literary prizes and contests as advertising tools for publishing activity. Because the previous studies are only focused on the fact of the impact of the prize on the promotion of editions but do not explain it, these aspects have been considered and introduced by me from the book production’s point of view. I investigated that the prizes and the contests in the literary field are effective marketing tools, which meet many publisher’s needs at the same time and can be considered a non-profit form of capital. I have reviewed the works of other authors, who accept that the economic success of the book is rising if the author is a winner of the literary prize or contest. I have found out that the book prize activates the demand for the book, and the literary contest is a tool to track the reader’s reaction to a future publication. In this way, literary prizes and contests can be considered as a way of conducting a marketing dialogue with the target audience. I have focused on the information support of literary national and international prizes and contests by the media, which attracts attention to the book and forms the reader’s interest. The literary prizes and contests are also considered as a way of exploring trends and their changes, familiarization the popular genres among the target audience and fixation the current choice of modern readers. Literary prizes and contests motivate the authors to improve their literary excellence, are the source of new authors and works, and assist in increasing sales of books. However, further research is recommended.</em></p><strong><em>Key words:</em></strong><em> book prize, book rating, literary contest, literary prize, functions of the literary prizes.</em>

The Impact

Psycholinguistic research into metaphor processing is burdened with empirical problems as experiments provide diverging evidence on the impact of conventionality, familiarity and aptness, and with conceptual issues as the interpretation and operationalization of the three concepts mentioned, as well as the related predictions which can be drawn from theories of metaphor processing, are controversial in the literature. This paper uses tools of statistical meta-analysis in order to bring us closer to the solution of these problems and reveal future lines of research.
