Abstract :
In order to understand the optimal design of the cable tray supporting system for the aim of fabric saving and energy saving and green manufacturing, the strength-stiffness ratio is proposed within the paper in nondimensional form, which defines quantitatively the relation between the static load strength and stiffness of the cable tray. On the reason of guaranteeing administration security, the connection between the strength and firmness of the cable tray under static burden is examined widely through the hypothetical investigation of the mechanical model. The weakest link within the carrying capacity of the

cable tray

also because the difficulty that has got to concentrate is proposed within the method of design and therefore the test of the cable tray. an inexpensive strength-stiffness ratio will help to make full use of the potential of cloth strengths. the value of the strength-stiffness proportion is reachable through the limited component strategy or by the loading test of the cable tray.. it's shown through the analysis that the worth of the str-ength-stiffness ratio being set within the range on the brink of but but 1 will make comparatively reasonable material utilization and may help the deflection test going smoothly to urge a relatively safer allowable working load for the cable tray.


1. Introduction :
With the rapid develop/ment of electrification and informatization in industry, the cable trays has become an indispensable basic element in industrial transportation and civil architecture, which have not only a wide range of demand but also considerable product yield and output value. In case of an accident during the service life, it'll cause big losses to the economy and society since the upkeep of the cable tray would be quite difficult. Therefore, the essential requirements for cable tray should cover the long-term safety and thus the reliable service performance, including the bearing capacity with the seismic resistance and thus the corrosion resistance. In recent decades, the developments are achieved theoretically, experimentally, and numerically consistent with various service requirements for cable trays. For example, the nonlinear response was studied with the damped behavior under seismic excitations . The dynamic analysis developed from the initial string model supported the idea from inextensible to extensible elastic beam models, considering the effect of bending stiffness, sag, inclination, and lateral components . A reduced cable tray support coupled model was proposed to research the modal resonant dynamics of cables with a versatile support. The nonlinear dynamic behavior of clustered tensegrity structures was analyzed employing a positional formulation by the finite element method . A design methodology was developed for the seismic qualification of safety-related cable tray support systems . In the case of anti electromagnetic interferences, the ampacities of cables laid on the cable trays were calculated by solving heat transfer equations and computed using the finite element method . There were the reports about the mutual electromagnetic coupling between cables in enclosed and open trays , the transfer impedance of an enclosed cable tray in terms of the ratio of width to height as well as the connecting scheme between cable trays , the analytical interpretation of electromagnetic interference between open cable trays of solid-bottom type , etc. For the flame retardant capability of cable tray, there are growing interests in understanding and predicting the hearth development since the cable tray fire in 1975 at Browns Ferry Nuclear Power Plant. Most of the work was concentrated on experimental and numerical analyses of cable tray fires, in either open atmosphere or in confined and mechanically ventilated compartments, as well as the fire behavior of the cable tray arrangements . The models for flame spread behavior were developed to estimate the heat release rate for the

vertical cable tray

fire and to predict the fire development of the cable tray based on the computational fluid dynamics.



In addition to the wants mentioned above, however, new demands inherit being for the cable tray, like the massive span, the lightweight, and therefore the simple construction along with the progress in industrial technologies, especially with the thought and recognition of the resource-conserving and therefore the environment-friendly societies. It should be pointed out that various meshless methods advance very fast in the regime of numerical simulations in recent years, which can yet be regarded expectantly as an effective means in the simulation of cable trays. Since the strength and stiffness are, as a matter of fact, always the most basic requirements of the cable tray, the relation between strength and stiffness of the cable tray are going to be discussed within the paper from a replacement point of view. In general, the strength refers to the capacity of a component in touch loads without damage, while the stiffness refers to the capacity of a component to resist deformation, of course the two concepts should not be confused. In terms of the wants of normal service, both the strength and stiffness of the cable tray must be satisfied absolutely at an equivalent time.



Actually, the security concerns of strength always take precedence over those of stiffness either in theory or in practice for any bearing component. However, it is often seen obviously the range of the wants for stiffness during a sizable amount of components in engineering. For example, the restrictions on deformation are very strict for machine spindles. In contrast, all types of springs require greater deformation capacity to understand the function of energy storage or vibration isolation. Although the deformation of various components is varied in size and form, the essential prerequisite for those components is to satisfy the need of strength.



In the process of the

cable tray manufacturing in India

, on the opposite hand, it's often the case that the deformation or the deflection measurement are going to be administered for inspecting the qualification of products, or for determining the safe working load because the basis of design, since the implementation of measuring deformation is more convenient than that of stress. What must be emphasized is that a structure works inevitably at an elastic state on the entire under the traditional service load correspondingly with a particular relationship existing between the load and deformation. From now on, following the concepts of energy and material saving and green manufacturing, the definition of the strength-stiffness ratio of bending beam is proposed for the cable tray in the paper. The relation between strength and stiffness of the cable tray is studied theoretically and comprehensively in-depth so as to market the optimal design of the cable tray under the premise of ensuring safety and to enhance the economic and social benefits of products.
