Fatigue Performance of Forged Steel and Ductile Cast Iron Crankshafts
Fatigue is the primary cause of failure of crankshafts in internal combustion engines. The cyclic loading conditions and the stress concentrations in the crank pin fillets are unavoidable, and can result in fatigue failure. The objectives of this study were to compare the fatigue behavior of forged steel and ductile iron crankshafts from a one-cylinder engine as well as to determine if the fati...
متن کاملBimetallic Cast Iron Rolls – Some Approaches to Assure the Exploitation Properties
Although the manufacture of rolls is in constant improvement, the requirements for superior quality rolls have not yet been completely satisfied, in many cases the absence of quality rolls preventing the realization of quality laminates or of productivity of which rolling mills are capable. In the selection of materials several factors have to be considered including the type of rolling mill, t...
متن کاملProbability Analysys for Rolling Rolls Calculation as per Probabilistic Method
Two calculation methods are mainly implemented during the construction as well as modeling of the rolling rolls. These are: deterministic (classical) and probabilistic – calculation based on reliability. When using deterministic method, starting point considers that the workloads as well as material specifications are invariable values. However, in reality, rolling rolls are burdened with varia...
متن کاملSteel, Cast Iron and Concrete: Security Engineering for Real World Wireless Sensor Networks
What are the real security issues for a wireless sensor network (WSN) intended to monitor the structural health of a suspension bridge, a subway tunnel or a water distribution pipe? Could an attack on the sensor network cause the structure to collapse? How easy is it for civil engineers or other domain experts to build a secure WSN using commercially available hardware and software? We answer t...
متن کاملDecoupling Control of Bridle Rolls for Steel Mill Drive System
A decoupling controller between the tension and speed of a steel processing line is proposed for bridle rolls of the steel mill drive system. With the controller, the tension of the steel strip is kept as a reference value, regardless of the line speed variations, and the speed of the strip is also kept, regardless of the tension variations. The controller generates a torque reference of each r...
