Transportation costs account for a large portion of business expense in any logistics firm; thus, achieving proper solutions that manage those transportation activities well and reduce such expense should be the number one priority for the business. Essentially, such logistics management involves the routing plans for company vehicles that perform delivery/pick up and also the number of vehicles utilized. This study investigated and compared the optimization performances of routing algorithms using simulated geographic data based in Chiang Rai, Thailand, emulating the post office operation which had 1 post office, 4 delivery vehicles and 2 delivery zones (2 vehicles per zone): 65 customer locations for zone A and 74 for zone B. The major objective of this particular routing problem, called Vehicle Routing Problem (VRP), was that the total delivery distance of those 4 delivery vehicles combined should be minimized; moreover, those vehicles mush finish their delivery operation within a time constraint, set at 2 hours. The optimization algorithms, employed for the routing procedures, were Large Neighborhood Search (LNS), Particle Swarm Optimization (PSO), Differential Evolution (DE) and Ant Colony Optimization (ACO), combined into 3 hybrid algorithms (LNS|PSO, LNS|DE and LNS|ACO). Those hybrid algorithms including pure ones (DE, PSO and ACO) were compared for their optimization performances; and the results showed that LNS|ACO hybrid algorithm was superior than the other two hybrid ones and also far better than pure DE, PSO and ACO algorithms at various parameter variants. Additionally, most algorithms (hybrid and pure ones) finished the delivery routing within the time constraint of 2 hours except only for the pure algorithms at minimum parameter variant.

A steering upright is one of the vital components in vehicle dynamics which links all suspension components between the wheel and therefore the vehicle. Upright provides the linkage between the upper & lower ball joints. The upright connects components as an example, control arms, steering arms, suspension springs, shock absorber, brake disc, wheels & tire. Steering upright is a part of mechanical system which contains the wheel hub and assembles to the suspension components. It's the pivot point of the steering and mechanical system, which allows the front wheels to show & more. Agenda of this project is design optimization of steering upright to achieve weight reduction along with required strength and stiffness. Optimized design of upright is necessary with correct material selection further as valid finite element analysis. Optimization is accomplished considering static stress, strain and total deformation analysis with acceptable material selection. Modal and Fourier analysis is to be performed to see natural frequencies and deformation. The experimental testing is going to be performed on UTM. By making the comparative analysis, result and conclusion is drawn.

In an electric vehicle, the wheels are one of the heaviest components of the vehicle. This paper aims to reduce the mass of the existing wheels for reduction in energy consumption as well as increasing the precision in steering. In this paper, an electric sedan is taken as the reference for studying the wheel and the boundary conditions are decided according to its specifications. Reduction in mass is achieved by designing a composite wheel for the boundary conditions. A reduction of 58% is achieved on the total mass of wheel.

In many recent years the use of composite materials increases in many fields, for example agricultural uses, where these materials are characterized by good mechanical properties, tenacity and light weight. Among many other materials for the reinforcement of composites, technical fabrics are increasingly being used for the same purpose, especially from carbon fiber, which have good mechanical properties. During tensile stress these fabrics are elongated in the direction of tensile force, and at the same time they contract crosswise in relation to the action of the tensile force. In this Project the tensile properties of regular carbon fabrics and woven fabrics made from carbon fiber yarns were investigated. Static structural analysis of Regular carbon fabrics and woven fabrics base carbon fiber specimen will be done using ACP tool in ANSYS 19 software.

The Body Control Module regulates the operation and coordination between the different parts of the car also by using signals of some sort. The various electronic parts of the vehicle are actually controlled by a Body Control Module – from the car light to the simple door locks; each part has a module that controls it. In today’s automotive setups, these modules are operating under a single assembly – they are now controlled by the Body Control Module. It may seem like the module performs a very complex function. Hence this Body Control Module has been protected from the damage during handling and vehicle running condition. This Body Control Module is subjected to various loading conditions such as vibration loading, Impact loading, mechanical shock. One of the case studies is doing to modify the existing Body Control Module. These modifications are carried out by using Computer Aided Engineering approach and verified by the experimental results. The software being used for the simulation is ANSYS and Ls-DYNA/explicit method
