چکیده
Conductive silicone rubber has great advantages for strain sensing applications. The electrical behavior of the elastomeric material is rate-dependent and exhibit hysteresis upon cyclic loading. Several constitutive models were developed for mechanical simulation of this material upon loading and unloading. One of the successful approaches to model the time-dependent behavior of elastomers is Bergstrom-Boyce model. The paper summarizes the results of investigations on the conductive silicone rubber as strain sensor. An experimental investigation of the sensors subjected to different timedependent strain histories is presented. Three different tests have been developed to measure timedependent and strain-dependent behavior of the rubber. To investigate the electrical properties, the resistance of silicone was measured during the mechanical tests. An adaptive neuro-fuzzy inference system (ANFIS) is used to approximate correlation between these measured features of the material and to predict its unknown future behavior. ANFIS has unlimited approximation power to match any nonlinear function arbitrarily well on compact set and to predict a chaotic time series.

متن کاملSingle-machine scheduling considering carryover sequence-dependent setup time, and earliness and tardiness penalties of production
Production scheduling is one of the very important problems that industry and production are confronted with it. Production scheduling is often planned in the industrial environments while productivity in production can improve significantly the expansion of simultaneous optimization of the scheduling plan. Production scheduling and production are two areas that have attracted much attention in...
متن کاملAn integrated model for multi-period fuel management and fire suppression preparedness planning in forests (Appreciated as the best paper of 14th International Industrial Engineering Conference)
Wildfires are of the forest-related disasters caused by inhumane factors. Spreading of these fires is due to the increase of the density of flammable plants. Two important approaches to prevent this occurrence are fuel treatment and fire suppression resources preparedness. In this paper, a mixed integer programming model is proposed based on the covering location and assignment problems which ...
متن کاملAutomating Asset Knowledge with Mtconnect.
In order to maximize assets, manufacturers should use real-time knowledge garnered from ongoing and continuous collection and evaluation of factory-floor machine status data. In discrete parts manufacturing, factory machine monitoring has been difficult, due primarily to closed, proprietary automation equipment that make integration difficult. Recently, there has been a push in applying the dat...
