Book Description
Disc brake technology used for mountain bikes, and mountain bike technology in general, has improved significantly as the sport of mountain biking has evolved. Disc brakes on bicycles are relatively new compared to their use on other vehicles. Rotor design is varied for rotors of the same intended use for many companies; some still use the same initial rotor designs that were introduced over a decade ago. Through the finite element analysis and optimization process, understanding the difficulties of designing disc brake rotors and the validity of certain design trends in current disc brake rotors is pursued. Additionally, this investigation uses finite element methods to design and optimize a mountain bike disc brake rotor using topology optimization. More specifically, the goal is to design a lighter rotor that maintains similar structural performance as rotors that are currently commercially available. The new rotor design was compared to two existing rotor geometries. The strength of the new rotor is comparable to existing rotors A and B. Weight improvements of 14.3% and 12.4% over rotor A and Rotor B, respectively, are realized.

Book Description
[Author abstract] The work in this study involves a conceptual design of a disc brake system. Disc brakes offer higher performance braking, simpler design, lighter weight, and better resistance to water interference than drum brakes. The objective is to find out the best conceptual caliper model design, with different materials and by subjecting them to same loading conditions, takin displacements and stresses into account. The study utilized different materials for three different conceptual models. The materials that were analyzed were Aluminum 2219-T87, Aluminum 6061-T651 and Graphite Silicon Carbide Aluminum Metal Matrix Composite (GrA-Ni). All the three different brake calipers were subjected to the same load conditions for each new material. The results were analyzed for given set of load conditions and were studied for displacements and stresses. The calipers were analyzed for pressure and tangential loads and the results were studied for deformation of the caliper body under stress. The results for the different models with different materials were compared to conclude the model with lowest deformation under same loading conditions.

Book Description
Stress and strain analysis of rotors subjected to surface and body loads, as well as to thermal loads deriving from temperature variation along the radius, constitutes a classic subject of machine design. Nevertheless attention is limited to rotor profiles for which governing equations are solvable in closed form. Furthermore very few actual engineering issues may relate to structures for which stress and strain analysis in the linear elastic field and, even more, under non-linear conditions (i.e. plastic or viscoelastic conditions) produces equations to be solved in closed form. Moreover, when a product is still in its design stage, an analytical formulation with closed-form solution is of course simpler and more versatile than numerical methods, and it allows to quickly define a general configuration, which may then be fine-tuned using such numerical methods. In this view, all subjects are based on analytical-methodological approach, and some new solutions in closed form are presented. The analytical formulation of problems is always carried out considering actual engineering applications. Moreover, in order to make the use of analytical models even more friendly at the product design stage, a function is introduced whereby it is possible to define a fourfold infinity of disk profiles, solid or annular, concave or convex, converging or diverging. Such subjects, even derived from scientific authors’ contributions, are always aimed at designing rotors at the concept stage, i.e. in what precedes detailed design. Among the many contributions, a special mention is due for the following: linear elastic analysis of conical disks and disks with variable profile along its radius according to a power of a linear function, also subjected to thermal load and with variable density; analysis of a variable-profile disk subjected to centrifugal load beyond the material's yield point, introducing the completely general law expressed by a an n-grade polynomial; linear elastic analysis of hyperbolic disk, subjected to thermal load along its radius; linear elastic analysis of a variable-thickness disk according to a power of a linear function, subjected to angular acceleration; etc.

Book Description
For more than a century, we have had a firm grasp on rotor dynamics involving rigid bodies with regular shapes, such as cylinders and shafts. However, to achieve an equally solid understanding of the rotational behavior of flexible bodies-especially those with irregular shapes, such as propeller and turbine blades-we require more modern tools and m

Book Description
Metal additive manufacturing (MAM) is an exciting emergent technology that offers the possibility of democratizing metal manufacturing worldwide. Many believe it has the ability to revolutionize product manufacturing on a global scale. MAM will require a considerable design shift for manufacturers and, hence, will disrupt conventional thinking and require adaptation. Visionaries in the mobility industry can see the transformative possibilities after materials considerations are addressed./ Materials Technology Gaps in Metal Additive Manufacturing introduces the reader to various opportunities and relationships in the study of material technologies involved in metal-based additive manufacturing of aerospace and automotive parts. Everything starts and ends with the material feedstock, and the intermediate processes that affect a particular metal. Each of the choices in the complex integrated MAM system impacts final-part properties. Edited by Dr. Cynthia K. Waters, from North Carolina A&T State University, Materials Technology Gaps in Metal Additive Manufacturing is a highly curated collection of 10 seminal SAE International papers. They discuss the various technologies involved in MAM, and draw attention to the materials needs in each of the situations addressed. The main topics included in Materials Technology Gaps in Metal Additive Manufacturing are: Process design and material modeling Metal powder selection and study Additive processing parameters' effect on materials properties As more interdependencies of material properties and possible manufacturing processes evolve (compatibility interdependence), questions if the specific manufacturing process is capable to create the required geometry will also arise. Materials Technology Gaps in Metal Additive Manufacturing brings innovative ways to address these and other challenges that are always present in the adoption of novel technologies.
