Compromise has to be made to satisfy safety standards and emission regulations by reducing the weight of components without or least compromising functionality. On the other hand, if the designer concentrates on emission only, then the safety standard is violated. Emission regulations are violated as the massive system causes more fuel consumption. If the designer only concentrates on safety, it makes the system bulky. It is a challenging task to attain safety standards and emission standards (BS-VI) for light-duty vehicles with our performance requirements. To design steering knuckle following requirements must be satisfied it should be strong enough, light in weight and inflexible during its service. The primary function of steering knuckle is to convert linear motion of the tie rod to the angular motion of stub axle. The steering knuckle is an essential part of the vehicle, which is connected to the front wheel with the help of a suspension system and chassis. Weight is always an essential criterion while designing any vehicle component.

New researchers working in the area will have an understanding of the procedures, and further, the techniques may be applied to design in general. In the case of automobiles, strength to weight ratio has to be maximized. The methodology may be applied to optimize structural components used in applications where the ratio of desired properties to the cost, generally in terms of weight, is to be optimized. The paper describes a research work carried out to optimize structural topology giving the essential details. In the second phase, design optimization of the model of steering knuckle is carried out, and excess material is removed at the region where induced stress is negligible as obtained in finite element analysis assuming standard boundary and loading conditions. The study on optimization of knuckle is divided into two phases, the first phase involves making of a computer-aided design model of the original steering knuckle and carry out finite element analysis on the knuckle by estimating the loads, which are acting on the component. This paper presents an effective topology optimization of steering knuckle used in a vehicle with the primary objective of minimizing weight. Increasing the efficiency of an automobile without compromising the performances is the major challenge faced by the manufacturers. The steering knuckle contributes a significant weight to the total weight of a vehicle. * e-mail: knuckle connects steering system, suspension system and braking system to the chassis.

almost 100 times lower than the yield strength of the material used. A weight saving of about 40% compared to the baseline rib design is achieved with only 10% increase in max stress, which is well within the acceptable limits, i.e.

Manual design modifications were required to ensure that the design was oneД¬ontinuous part and that the optimized design could be manufactured easily. The results obtained are then manually interpreted to ensure that it conforms to manufacturing constraints. The optimisation is performed using Ansys Workbench. This is achieved by exploring the problem of minimizing the mass of an aircraft wing box rib structure without compromising its structural integrity. The objective is to minimise the overall weight of an aircraft and increase fuel efficiency, thereby reducing the operatingД¬ost and greenhouse gas emissions. This paper examines the current state of topology optimisation technology and investigates how topology optimisation can be utilised in the aerospace industry. The topology and shape optimisation are sub-fields within structural optimisation. To fulfil the safety, strength and endurance requirements of a component, design tools such as topology and shape optimisation can be utilised during the early stages of the design process. The selection of material and design of components are two fundamental topics in the industry for producing sustainable and competitive products.
