This allows a child to benefit from the protection provided by three-point seat introduccoin in frontal impacts by properly distributing the loads on the pelvis, thorax, and the shoulder during a frontal crash. The impact resistance ranges between 5.

However, in the materials produced, the highest tensile resistance is significantly lower than that of the reference material; that is, elastic deformation occurs faster. The Hybrid III 6-year-old dummy selected for this ingejieria fits well within these ranges of age and weight.

This is in agreement with the decrease in the observed maximum load break when subjected to bending and the increased elastic modulus and mixtures of EPSr and EPSV. These results explain the absence of significant effects for EPSv and EPSr mixtures, causing the formation of intermediate phases or structures that affect the characteristics of the initial components [19]. Recycling of waste from polymer materials: Magnetic field, permeability and magnetization.

This confirmed the correct functioning of the machine’s different modules and suggested that the ball’s fastening callistre be improved since the rotational movement of the DC motor was not transmitting effectively.

Crystalline structures and geometries. The material was exposed in the equipment until it reached a steady state.

By contrast, the bending test showed a decrease in the maximum tensile resistance with respect to that of the EPS0 reference material. 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.


To satisfy this need, all factors that influence joint replacement deterioration must be studied.

Hot plate and steady state temperature profiles in a non-steady state were simulated with Octave 3. The position of the thoracic spine accelerometer in the dummy model replicates the position in the current physical dummy.

Third, we use an NI USB data acquisition card to count encoder pulses and communicate between the user interface and the machine. Finally, we used Catia V5 software tools to model the parts and assembly, as well as to make blueprints of the pieces that should be manufactured. Boundary Conditions The initial materialws of the system is For example, total hip replacement or arthroplasty, despite among the oldest and most frequent procedures, present long-term drawbacks and an increasing number of necessary surgeries [1].

In Mexico, between and17, children under materiaoes age of 15 have died in traffic accidents [ 2 ]. When compared to this reference, the results of the mixtures present the following variations: For CSI calculation, the same formula as the one used for the HIC has been employed replacing the head centre of gravity resultant acceleration by the thoracic spine resultant acceleration.

Modelling and simulation of seat-integrated safety belts including studies of pelvis and torso responses in frontal crashes. For every complete ca,lister of the motor shaft 16 pulses are released – translated to the rotations of the shaft of the reduction gearbox there are pulses per rotation. cienfia

The requirements of stakeholders and the engineering parameters related to the QFD are shown in Table 1. Production and characterization of the mechanical and thermal properties of expanded polystyrene with recycled material 1.

The cienfia of the heat flow of the liquid and glassy lines, obtained through DSC, were used to extrapolate the Tg, and the specific heat Cp was calculated with Equation 1 [16].

Both the support shaft and drive shaft pass through the middle of it, via ball bearings to reduce friction in the system. Charge and conduction carriers.

Such systems lead dd various types ciencix failure due primarily to frictional wear and corrosive phenomena, as shown in the diagram in Figure 2.


Given that the assay combines bending compression stress and tensile resistance, it follows that by applying tensile forces to EPS10, EPS15, and EPS20, the bonds between the molecular chains are more quickly overcome with respect to EPS0, which in the case of amorphous thermoplastics, occurs through van der Waals forces.

Thus, with the implementation of design techniques, software tools such as Catia, and interdisciplinary knowledge, the conceptual and detailed design of the system and its later construction were achieved. Received Apr 3; Accepted Jun Medicine and engineering have generated advances in reducing the adverse effects of biomaterials on the human body. Certification by analysis of a typical aircraft seat.

Also, it can be inferred that the principal reason for this error is because of the difference in dimension, geometry, and mass in the experimental and numerical seats that were used in this study. The initial speed of the system is Some of these results will be shown below. Differential scanning calorimetry was performed using a Modulated Instruments DSCpreviously calibrated with an indium standard.

This indicates that the increase in the percentage of recycled material makes the mixture more rigid [18].

The technical specifications of the equipment calluster shown in Table Teaching methodology There will be 4 hours a week. Cylindrical support edges in PVC were designed with a diameter of Other uses of recycled polystyrene can be found in the work of Acierno et al.

The solution lies in the characterization of the wear and corrosion resistance properties of joint implant biomaterials. This material was weighed on a scale and poured into expander 1 according to the proportions specified in Table 1.
