“…The von-Mises stress is utilized to predict the appropriateness of the material for a particular set of loading conditions. If the von-Mises stress is higher than the yield strength, the material is said to be crumpled (7) . It is generally used to study the failure behaviour of the ductile components.…”

Background/Objectives: The main objective of this study is to propose a new design of go-kart chassis and to assess the ability to bear the front, rear and side impacts on this proposed design. Another goal of this study is to make this design with different materials and also to test them in different loading conditions. To determine the safest material for the proposed Go-Kart chassis design based on the results obtained. Methods/Statistical analysis: A new and lighter go-kart chassis model is proposed in this study. A 3D go-kart chassis was modelled and its Finite Element Analysis was carried out on Autodesk fusion 360 software. Global test standards were used to simulate the impact behavior on go-kart chassis. In addition, this Go-kart chassis design was also made from three different materials i.e., AISI-4130, Al-6061 and CFRP composite. These Go-kart chassis were tested under different loading conditions. A comparative study of the obtained results was also carried out. Findings: The results of simulations performed under different conditions, showed this design has demonstrated adequate resistance against deformation in front, back and side impact tests. In every situation, factor of safety was more than one. Therefore, it can be inferred that the proposed design was completely safe under testing conditions. Under different loading conditions, the design made up of CFRP composite was safest among all the materials used. However, detailed modelling and simulation studies are needed before testing it in real-life conditions. Novelty/Applications: Go-kart type of small vehicles are primarily used for recreational and racing purposes which are mainly powered by batteries as well as low capacity engines. The lower weight and better design of the chassis have the ability to improve their performance to a great extent.

This paper discuses design and development of the most essential components of new feature press brake bending machine. In this study, the right angle lever design used to construct new developed one hydraulic cylinder driven press brake bending machine. In addition to this we develop three port double acting actuating cylinder for driving two lever mechanism of the machine. This cylinder both ends mount on lever effort arm point in horizontal direction. In case of press brake bending down ward bending force is needed, for that it needs a mechanism that convert horizontal direction force into a vertical down ward force. Right angle lever is perfectly satisfy this need, for that we develop two lever mechanisms that is at the right and left side of the machine for handling and converting the direction of both cylinder end forces. In this machine lever have a great roll in addition to converting the direction of force it used to maximize the input piston force. The remaining components of the machine is used to help the lever for achieving its application. All current hydraulic cylinder driven machineries uses only piston force for the purpose of drive its mechanism while cylinder force is lost on cylinder support without any function and it is the main cause for machine failure. The main objective of this paper is to develop new feature hydraulic press brake bending machine that solves the problem we observe from current hydraulic cylinder driven machineries. As a result the machine become light in weight low in cost, easy in maintenance and automatic in operation. The mechanical advantage of the mechanism is 6 times per one cylinder as compared with hydraulic cylinder driven machineries that available in the market. The maximum capacity of the machine is to bend 5mm thickness and 1250mm length AISI 1034 stainless steel sheet with a maximum bending force of 524725N. This maximum bending force is generated from 87454.16N piston force. The critical component of the machine is right angle lever, link, upper beam, lower beam, Machine table, machine frame, three port double acting actuating cylinder, , punch and die.

Rotary motion is generated from a crankshaft’s piston alternating motion using a connecting rod. The engine combustion gases and components motion of inertia exert pressures that induces compressive and tensile stress in the connecting rod respectively [1], [2]. Connecting rods fail due to its overloading, bearing failure, irregular adjustments of the bolts and faulty assembly or fatigue [3]. It is important for connecting rods to be able to withstand the complex high tensile loads that acts on them. As a result, numerous design technology, material selection, working and fatigue test of a connecting rod have been studied and presented [4]. Mechanical properties (such as hardness, tensile strength, rigidity and fatigue resistivity) of the materials used in the manufacture of a connecting rod need vehicles depends on the design of the connecting rod. Failure of connecting rod is attributed to the in availability of much strength needed to hold the load. This can be overcome with the life cycle extended by increasing the strength [5]. Finite element analysis of connecting rod have been conducted and presented by a lot of researchers. In [6], theoretical and FEA of an IC engine connecting rod was conducted. The result of the analysis obtained shows the causes of failure at the fillet of both ends due to the induced stress. In [7] static FEA for fatigue, deformation and weight optimization of a connecting rod using ANSYS workbench is carried out and presented. From the suggested design changes obtained from the weight optimization result, the failure result is further updated to achieve a better result. In a paper by Bansal, dynamic stress analysis was carried out on a single cylinder four stroke diesel engine connecting rod of Aluminum material using FEA. The optimization was also done under dynamic loading with the boundary conditions and inputs determined from the pressure-volume diagram and engine specification chart respectively are carried out with different meshing size for an accurate result. [8]. FEA is the commonly employed computational tool for testing and modifying engineering structures within certain design limit. It involves diving in to small units known as ‘elements’ for static and dynamic analysis of simple to complex model under different design constraints. Further investigation can also be done to improve the design for optimal performance and lifespan with regards to design failure [9]. Many kinds of literature have worked on weight optimization. Gaikwad in his paper modifies a roller conveyor by performing weight optimization after carrying out static analysis on the roller conveyor [10] In another paper by [10] the weight of a roller conveyor was reduced thereby saving the materials under specific load constraints using finite element method. In this paper shape optimization with target weight reduction rate of 20 to 60% with an interval of 10 under a static loading of 100N. Further analysis for structural optimization is also done to determine a new optimized structure with new deformation and stress values respectively. The analysis is carried out in ANSYS static structural, mechanical solver with a tensile force of 100N acting on its larger end.
