This work uses the Generative Design approach to achieve a weight reduction of the wishbone arm used in the vehicle suspension system. The suspension system of Haynes Roadster an open two-seater club racing car is taken for this study. Detailed calculations were done to understand the dynamic loads acting in the wishbone arm during acceleration, braking, and cornering. The above-calculated loads, material, domain, fabrication techniques are used as design parameters and weight reduction as the objective in the Generative design to obtain a final output. The various design iterations will be proposed by the algorithm based on the parameters and objectives defined. Generative design uses a machine learning approach which is time-saving and also eliminates the need for redoing and refining the initial designs by giving us optimum designs based on our usage as well as manufacturing requirement at the early stage.

The objective of this work is to present the study on experimental data of the strength characteristics of Carbon fiber reinforced thermo-set polymer tubes used in manufacturing of Formula SAE racecar suspension. The detailed explanation of a new approach used in fabricating high quality tubes is described and a comparison is formed between two techniques. The design objective of reducing weight while maintaining the structural integrity is met. A balance between stiffness, weight, strength, manufacturability and cost must be maintained in the suspension components of any racecar. There are three driving factors that make composites the ideal material for application in many suspension components in the Formula SAE competition: weight, stiffness and strength. Composite materials can be tailored to meet the axial tension-compression load paths that pushrods, A-arms and steering arms undergo better than any other material due to their anisotropic properties.

Natural fibers are extracted from plant can be used as a fiber reinforcement in polymer based materials which provides anisotropic mechanical properties due to their interior microstructure. In our county, flax fiber is available in nature abundantly which is widely used for manufacturing of composites for automotive and aerospace application. In these work, young modulus of fiber composites is determined by using mathematical models. Finite element model is used to determine the modulus properties of flax fiber epoxy composites by varying fiber ratio. The analysis results indicated that finite element model results are correlated with mathematical of flax fiber reinforced epoxy composites.

Fundamental frequency determination can help us to find where the resonance will happen. The need of dynamics characteristic is one of the major concerns to find the natural frequency. This paper aims to find the natural frequency of a laminated composite plate and optimizing the plate to get maximum frequency. Finding the optimum design by experimentally are more expensive. To avoid the complications now a days the researchers are using computational method.

Safety is a major concern addressed in various industries and most specifically in transportation industries. Road accidents are undoubtedly more frequent and are responsible for many permanent disabilities deaths worldwide. Many works have been done to improve the safety of different vehicles as the number of accidents is increasing. The main objective of this work is to further improve road safety by providing instantaneous warnings to drivers about hazards in their intended path in hilly region. This further it aims to provide a pleasant and peaceful hill travel and to avoid any possibility of accidents in hill curves. The roads in these hilly regions are always filled with many hectic and endless curves. These curves are classified into Hair-Pin Curves, Salient Curves and Re-entrant Curves. These curves offers partial or no visibility about the incoming traffic for the drivers.

In this work, a Carbon Fibre Reinforced Polymer (CFRP) Wheel Centre (WC) is designed targeting key parameters such as reduced un-sprung mass and lower rotational inertia in vehicle dynamics. A Keizer Aluminium Wheel Centre was used by the team previously and it weighed around 1.8 Kg. Designing of CFRP Wheel Centre was based on previously used Keizer Aluminium wheel centre considering the design constraints such as distance between hub and wheel assembly. This was done to ensure the same trackwidth within the Formula Student rules. Initially, the Finite Element Analysis (FEA) was carried out for the Keizer Aluminium wheel centre and the results were analysed. For the same design CFRP material was used and the result was found out to be promising with a wheel centre weight of 1.3 Kg. Further to improve the performance and weight reduction, FEA was done to design a 38 layered CFRP wheel centre giving utmost priority to ease of manufacturability and safe design.

At Micron-level actuation, thermal gripper provides greater forces when compared with electrostatic mode of actuation. To accomplish larger translations at minimal voltages, the Electro thermal actuation is applied. The mechanism of selective non-uniform Joule heating; which helps in thermal expansion of the design owing to restraints. The gripper proposed in this work is analyzed using FEA and is fabricated using Aluminum and stainless steel to achieve quicker response. The in-plane displacement, strain, stress, current density and temperature have been predicted for different magnitudes of current-voltage combination that the gripper sustains. It was found that, micro gripper performs well under 1v giving 60 μm displacement. Parametric sweep was carried out using commercially available FEA software package; COMSOL Multiphysics, to study and asses the outcome of various parameters on the performance of the gripper.

Waterjet machining is a widely used advanced machining technique because of its versatility in removal of material for a wider range of materials. Waterjet machining is particularly advantageous in the precise cutting of advanced materials like Fiber Reinforced Polymers (FRPs) comparative to conventional machining methods. The conventional machining methods result in the release of high amount of glass fiber dust which leaves the work environment unsafe for the workers. The material dust if inhaled can lead to acute respiratory diseases. In this work an analysis was done on the cutting performance of Waterjet machining and is presented based on an experimental investigation on fabricated fiberglass reinforced laminates. It is shown that with a good combination of cutting parameters such as nozzle traverse speed, waterjet pressure, and Stand-off distance a cutting performance can be achieved.

Individuals with mobility impairments are people who have lost their functionality of leg and hand due to birth, diseases or accidents. Various commercial bike designs are existing in the market for bike riders with disability in their legs designed with dummy rear axle. But no designs exits for bike riders with disability in their hands which is being available in market. To ride a bike steering, brake and acceleration controls has to be provided by an alternate method. It was proposed to develop a bike for person with disability in their hand. The design of the bike and in particular steering system was done using of Autodesk Inventor software and analysed using ANSYS workbench to assess the structural integrity of the design. The design was transformed in to a complete working prototype and found to be working satisfactory.
