Design Mechanics

Greenhouse gas emission, fast depletion of fossil fuels, the oil crisis and the increased cost of petroleum products are the major factors that need a shift from internal combustion engines to Electric Vehicles. The use of electric cars is an active action in conserving the environment. The use of these cars promotes the protection of the environment by reducing greenhouse gas emissions while promoting renewable energy sources that are less likely to amount to the carbon footprint. Electric cars function by plugging into a charge point and taking electricity from the grid. They store the electricity in rechargeable batteries that power an electric motor, which turns the wheels. Electric cars accelerate faster than vehicles with traditional fuel engines so they feel lighter to drive. India launched "National Electric Mobility Mission Plan (NEMMP) 2020" in 2013, which aims promotion of hybrid and EVs in the country to achieve national energy security. Even after this the total sales of EV's in India was only about 0.0068% of the total sales of vehicles in India. Increasing long-term gasoline price and concerns on the impact of emissions have inspired alternative technologies like electric vehicles (EVs). The automotive manufacturers are facing difficulties in understanding the needs and wants of the customer. This research aims at helping the automobile manufacturers to understand the customer better. The insights gained from this research will help policymakers around the world in crafting transportation and energy policies in the EV transportation system. Lack of study on this topic in India is the reason for a gap in consumer adoption and scientific research EVs. Filling that gap is the motive of this research overall, this project involves processes like design, analysis, fabrication and assembling of different components.

In this article, I outline a logic of design of a system as a specific kind of conceptual logic of the design of the model of a system, that is, the blueprint that provides information about the system to be created. In section two, I introduce the method of levels of abstraction as a modelling tool borrowed from computer science. In section three, I use this method to clarify two main conceptual logics of information (i.e., modelling systems) inherited from modernity: Kant's transcen-dental logic of conditions of possibility of a system, and Hegel's dialectical logic of conditions of in/stability of a system. Both conceptual logics of information analyse structural properties of given systems. Strictly speaking, neither is a conceptual logic of information about (or modelling) the conditions of feasibility of a system, that is, neither is a logic of information as a logic of design. So, in section four, I outline this third conceptual logic of information and then interpret the conceptual logic of design as a logic of requirements, by introducing the relation of " suffici-entisation ". In the conclusion, I argue that the logic of requirements is exactly what we need in order to make sense of, and buttress, a constructionist (poietic) approach to knowledge.

The Fractal Wheel Bearing CVT provides advanced new ideas in technology and applies to multiple areas of research, such as physics , engineering, crystallography and also sheds light on ancient technology because of it's simple manufacturing methods which require no modern tools.  Some people who want to read this paper to learn more engineering principles might be confused by the theoretical physics aspects as well as the ancient technology connections.  I hope to spur interest in the subject.  Even though I have a wide range of experience in industrial applications, I am focusing on the theoretical physics aspects most of all and you can read more about that in the sister paper on this site.  In order to be more practical a group of people will have to delve into the complicated theoretical end and the mathematical formulations are time consuming and difficult.  Fortunately, many of the theoretical Quantum Field Theories offer pre-cooked formulations that can be easily ported for use in engineering.  Those formulas when converted for engineering use will be beneficial to the practicing engineers.

The rolling resistance of a tire is described as a force opposing horizontal motion on a surface. As rolling resistance for a given tire size, inflation pressure and vertical load are may be different between radial-ply and bias-ply tires, this study was mainly conducted to predict rolling resistance (R) of radial-ply tire based on tire size, viz. section width (b) and/or overall unloaded diameter (d), inflation pressure (P) and vertical load (W). For this purpose, rolling resistance of four radial-ply tires with different section width and/or overall unloaded diameter were measured at three levels of inflation pressure and four levels of vertical load. Results of rolling resistance measurement for radial-ply tires No. 1, 2 and 3 were utilized to determine multiple-variable regression models and three-variable linear regression model R =-0.17827 + 0.00465 d-0.00168 P + 0.03161 W with R = 2 0.976 was selected. Also, results of rolling resistance measurement for radial-ply tire No. 4 were used to verify selected model. The paired samples t-test results showed that the rolling resistance values predicted by model were statistically less than the rolling resistance values measured by test apparatus. To check the discrepancies between the rolling resistance values predicted by model with the rolling resistance values measured by test apparatus, RMSE and MRPD were calculated. The amounts of RMSE and MRPD were 0.017 kN and 10.81%, respectively. Rational amounts of RMSE and MRPD confirmed that selected model may be used to predict rolling resistance of radial-ply tire based on overall unloaded diameter, inflation pressure and vertical load. However, to calculate actual rolling resistance values or rolling resistance values measured by test apparatus (R) based on rolling resistance values predicted by model (R) the linear equation R = 1.011 R + 0.013 with M P M P R = 0.958 can be robustly suggested. 2

This paper describes the design and 3d print of an explorer robot with suspension rocker-bogie which is
based in the robots sent into space. Also, it describes of software to acquire the image in real time and the
control of robot. It should be noted that space exploration has been a feature of governments for many
years. Nowadays there are companies that can transport loads to space; There are also companies that
have made great advances in robotics and manufacturing.These technological advances can help in space
exploration, either by making robots lighter and easier to manufacture or even by creating pieces and tools
from space.

The local stress concentrations around the discontinuities and the weld defects are fairly common. In this study, the investigation of thickness and stress concentration effects on fatigue strength (FAT) have been studied. The fracture mechanics tools and fracture analysis code (Franc2D) were used to consider these effects. The FE simulation of welded joints will provide a tool to determine the regions of stress concentration which in turn determine the crack initiating and FAT. Unfortunately, these tools are unable to calculate FAT at higher thicknesses. Therefore, the crack length was corrected with a suitable scale. The determination of fracture toughness values without the need to undertake experiments have been presented.
