The support shaft moves linearly with the purpose of changing the ball when necessary, which is why we employ a linear press ee a ball bearing installed on top to house the drive shaft, giving it the power to move manually when required.
The purpose of this study then was the design and calloster of a machine for testing micro-abrasion and micro-abrasion-corrosion, in order to assess the wear and corrosion of materials that can be viable in the field of orthopedic surgery, especially joint replacement. Both the support shaft and drive shaft pass through the middle of it, via ball bearings to reduce friction in the system.

Medicine and engineering have generated advances in reducing the adverse effects of biomaterials on the human body. Be the first to review this item Amazon Best Sellers Rank: The first step was to define the problem – to describe the problem in detail, including objectives, restrictions, concepts, fundamentals, and needs, all in order to begin with the design process.
Discover Prime Book Box for Kids. Such systems lead to various types of failure due primarily to frictional wear and corrosive phenomena, as shown in the diagram in Figure 2. The versatile design of the sample holder allows us to affix samples of any shape. Joint ingenueria, due to the interactions between the various parts in contact and to constant movement, generate wear mechanisms from the action of friction between the surfaces and the contaminant particles between them, causing anything from thin cracks to deep grooves .
Using modern design tools, we carried out a systematic and organized process, with greatest emphasis on the requirements most important to stakeholders, such as test accuracy, geometry ingsnieria size of the samples to be tested, and the modularity of the equipment.
The technical specifications of the equipment are shown in Table 5: High wear ingenierai to minimize debris generation. Would you like to tell us about a lower price? Read more Read less. It also allows one to work in different work materizles to perform the assembly of the parts, engineering blueprints, and cinematic simulations of the different elements Figure Figure 4 illustrates the process used to satisfy the posed need.
This modular and versatile machine was constructed for performing micro-abrasion and microabrasion-corrosion testing.
The result was a diagram that shows the connectivity of the elements, in which four subsystems can be seen Mechanics, Electronics, Electrochemistry, and Softwareeach important in achieving our objective of designing and developing the apparatus Figure 8. At this state of design we also identified technical difficulties, which lie in the adaptation of the actuators, the sensor system, and minimizing the number of parts, parameters that have a strong relationship with the modularity of the bank.
For every complete revolution of the motor shaft 16 pulses are released – translated to the rotations of the shaft of the reduction gearbox there are pulses per rotation. With sub-functions defined, we generated alternative solutions for each.
Tellez, “Design and development of transcutaneous electrical stimulation equipment for neuromuscular rehabilitation in individuals with facial palsy. East Dane Designer Men’s Fashion. Materials and methods The solution lies in the characterization of the wear and corrosion resistance properties of joint implant biomaterials.
Initially, we performed a physical decomposition of the system to be designed. Amazon Drive Cloud storage from Amazon. Third, we use an NI USB data acquisition card to count encoder pulses and communicate between the user interface and the machine. To generate the simulated conditions, we designed an acrylic tank within which the test is conducted.

The requirements of stakeholders and the engineering parameters related to the QFD are shown in Table 1. After weighting the objective tree, the weighted decision matrix was created.
The abrasive slurry will be mixed by a magnetic stirrer and transmitted by a peristaltic pump. Titanium nitrides are the best known among these. With our design goal in mind, we established the main variables for the design of the equipment. Additionally, adding an electrochemical cell to the system allows us to monitor corrosive phenomena.
Figure 11 shows the tasks performed by the devices in order to fulfill the main function of the machine, with their respective input and output streams that indicate how tasks interact directly and how different elements are grouped into modules to carry out micro-abrasion or micro-abrasion-corrosion testing Table 4. Inenieria resistance to cyclic loading generated by the joints.
Among the electronics used in the development of machine we first have a Hall effect encoder, which generates a leading edge and a trailing edge signal for measuring motor spin. For all, rotational energy is to be provided by an electric motor with encoder controlled by Labview software interface.
According to the matrix, the comparison between the three design proposals suggests Design 3 as the best design, with a rating of 8. English pdf Article in xml format Article references How to cite this article Automatic translation Send this article by e-mail.
These make use of a potentiostat and an electrochemical cell comprised of a working electrode the material to be assessedan auxiliary electrode, and a reference electrode in contact with an electrolyte medium which in this case is the solution simulating the biological environment. Starting from the proposed scheme we began modeling the system describing the flow of energy, matter, and information signals present in the system, using arrows and function blocks in a standardized design language .
After obtaining our design alternative, we continued on to the production of the machine. In this step we also obtained valuable information from the stakeholders, or the future users of the system, such as members of the Volta research group, who have extensive expertise on the subject.
Because we are studying corrosive phenomena, the parts in contact with the balls were designed to be manufactured in EMPACK or Nylon 66, thus isolating the system. Others, however, such as titanium and niobium carbides, are already being implemented with very little study of their tribological properties .
In the beginning of the functional analysis, the inputs and outputs of the system as a whole were identified in order to build a black box diagram that describes the main function. Preliminary tests were conducted with AISI steel balls on specimens of L steel, under the influence of Ringer’s lactate with aluminum particles in suspension. We cinecia different design concepts with each that meet the design target proposed for future evaluation.
Generally, a biomaterial must have the following properties [6,7]:
