اجرای مهندسی معکوس برای صنعت تولید میل لنگ

In this modern world, there are always pressure on the designers and the manufacturers to respond to the consumer needs. Engineering involves designing, manufacturing, constructing, and maintaining of products, systems, service and structures. In this paper, an attempt has been made to derive all the parameters, which are necessary for designing the components of an engine using reverse engineering. Even though lots of methods are available for redesigning, the reverse engineering is selected. Computer aided modeling using CATIA and optimization analysis of crankshaft is used to study was to evaluate and compare the fatigue performance of three different materials of automotive crankshafts, namely forged steel, ductile cast iron and aluminium alloy. In this study a dynamic simulation was conducted on three crankshafts, cast iron and aluminum alloy forged steel; from similar single cylinder four stroke engines. The dynamic analysis was done and was verified by simulations in ANSYS. Geometry, material and manufacturing processes were optimized considering different constraints, manufacturing feasibility and cost.The maximum stress point and dangerous areas are found by the deformation analysis of crankshaft. Possible weight reduction options and their combinations were considered. Thus durability of feasible material and analysis is carried after weight reduction carried to the feasible material. Thus more possibilities of feasible crankshaft are found out.
