This rubber, coded as the BX rubber sample, is simultaneously loaded and subjected to linear vibrations. A multiplicative non-separable variables law of the Nashif has been used to model the behavior that depends on both stretch and frequency. This method allows splitting the intricately combined test performed jointly on both stretch and frequency. On the one hand, we use Young’s complex modulus E∗(휔) calculated from the experimental data, and on the other hand, the hyperelastic characteristics E(휆) of the same material obtained from the experimental tensile curve. The hyperelastic phenomenological Gent–Thomas model and the hyperelastic molecular Flory–Erman model are used to evaluate the combined complex modulus E∗(휆,휔). We obtain results that go in the physical sense, i.e, Young’s modulus increases when the material is stretched, while the damping decreases.

Each is governed by its own principles of evolution or equilibrium such as balance laws or constitutive laws. Many engineering problems can only be described correctly by coupling fields of physics that have historically been developed and taught separately. These problems require on the one hand a good understanding of each physical domain, but above all an analysis of the coupling mechanisms of these physical domains, in order to propose a relevant model capable of solving the problem. A challenge in the multiphysics (mechatronics) field is the construction of coupled multiphysics models from experimental observations, as well as the analysis of their mathematical properties. The mathematical analysis of the coupled model must be able to show the well-posedness of the problem at the defined boundary and initial values. For this reason, we have identified several coupling metho...

The design of mechanical systems requires innovation, creativity through technological research. The related feasibility studies are full of many parameters, not very effective, and take place in a concurrent and varying environment. It is therefore difficult to conduct them effectively. The costs of the factors of the product life cycle are listed in the literature. These are the costs of design, manufacture, distribution, operation, and recycling. Those intrinsic to the expression of its life cycle costs are identified. This allows structuring an approach of economic estimation of the feasibility. The defined cost indicator allows measuring the feasibility of a design project. This "cost" criterion is the basis for indicating the relevant tools and methods for storing the technical data according to the system requirements and for coordinating the partners in c...

Competition on product quality and performance has become the main factor that companies face in today's market. These pressures are driving technological advances to provide systems with a constant increase in performance at reduced costs and in shorter delivery times. The performance includes better interoperability, improved reliability, good safety and smaller size that have determined the birth of mechatronic systems. Obtaining a product with these qualities in a reduced time would be beneficial for design companies if they follow an efficient design model appropriate for complex system. In this context, this paper conducts a discretized study on the main mechatronic design patterns in order to make their use understandable for the design of mechatroni...

Dis/reassembly activities are delicate and need precise intervention due to the obligation of equipment refunctioning constraints. Time spent for dis/reassembling faulty components should be well-deducted and standardized. It is not always the case due to the various variant disassembly metrics and contexts. The Work Factor Method during dis/reassembly activities helps to develop the operational dis/reassembly time models. These models contribute to defining effective Time as far as operational dis/re-assembly activity is concerned and can help to optimize maintenance and recycling task planning.

Looking for maintenance non-productive activity time is not an easy task because many uncontrollable parameters involve in the task processes. Also there are many work time measurement methods, but choosing one among them should be responding to each real work context which is always variable and evolutive. Working measurement is analyzed here and a justified initiative guideline is proposed for helping choosing convenient time measurement methods according to each or cumulative job situations. Illustrations in maintenance cases are outlined. Such information is very valuable for a good look-ahead planning and scheduling as far as deducting of work reference time and work management are concerned.

The same interest can be found in mechatronic topological approaches where many disciplines should be fit together, facing therefore many and variant constraints. Distinguish topological approaches are found in the literature. Many are more specific for a single domain than a complex system. Two main classes of topological approaches are structured. The first class is based on a theoretical approach that states the KBR topological graph and the MGS language while topology is primarily structural form. These topological modeling approaches tend to combine two disciplines of a Mechatronic system. The second class is the disciplined approaches that recapitulate the topological approaches of each mechatronic discipline. The topological optimization of the mechanical, electronic and control model is summarized. In the light of the literature, there is a lack of a specific topological method for a mechatronic system that encompasses the structural complexity of complex systems. Since the topology is first and foremost a structural shape, the mechanical topological model, which is structurally based, should constitute the algorithmic foundation by integrating the functional and structural constraints of other disciplines.

The multi-technological character of Mechatronics makes the design of systems more complex. In this context a general knowledge of Mechatronics and Mechatronic products is necessary. The design problem of a mechatronic product requires the analysis of its structural, technological, and functional complexity. This paper presents an approach to the design of Mechatronic systems. This requires the characterization of the different types of the complexity of a product before presenting the design methodology, the modeling, and the simulation tools used in the different design phases.

At these early stages, the process engineer has maximum degrees of freedom in the plant and process specification. The engineer is free to consider basic process alternatives such as fundamental technology and chemistry and the location of the plant. The modeling of inherently safer process alternatives that we call safety features to be integrated in the process design is the main objective of this paper. This is because each CAPP domain (assembly, machining, inspection, safety, etc) has been treated independently. And the “feature-recognition” has been adopted as the unifying theme. Indeed integrate safety during the life period of machines is costly and sometimes destructive. For that purpose to be achieved safety features are defined and taxonomy attributed based on the function of t...

The most valuable part of the plant is the oil content of the seed kernel. For optimum oil extraction, the seeds must be peeled almonds and separate the hulls. The separation of hulls almond is generally done manually which requires hard work and very time consuming. Also, use non cracked seeds produced low oil recovery. Hence the need to develop an equipment capable of mechanically carry out the separation of hulls and almonds. This work therefore aims to scale winnowing equipment for mechanical separation of the shells and kernels of seeds of Jatropha curcas. To carry out this work, we conducted a theoretical study of the physical properties related to the size and the terminal velocity of kernels and shells of Jatropha curcas and we made a design methodology application linked to the functional analysis to design the winnower. The main results obtained following this ap...

Maintenance operations are necessary to establish or maintain equipment in a good functioning state. In this light, to evaluate the equipment disassembly procedure aims to reduce from the design phases the difficulties encountered by the maintenance staff during maintenance activities. These difficulties result from the lack of consideration of criteria such as: the accessibility, modularity, the force (couple) necessary for disassembly, the actor posture, the precision, etc. The estimation of these qualitative and quantitative criteria requires putting in place a structural method. The interest being to give information and appreciation on disassembly of equipments, make forecasting of eventual amelioration without compromising functioning. The method "weighted voting" allowed in this paper to anonymously gather information in a consensual manner from working group members (maintenance actor, ergonomist, designer, and expert) on criteria or parameters linked to the disassembly of each module or component of an electrical hand drill, during disassembly. The disassembly time was evaluated up to 1.72 minutes. If the working group judges the necessity to reduce the disassembly time, design for maintenance actions should be proposed.
