Mechanical Power Weeder- Design And Development

The economical growth of any country is divided in various sectors of the business contributing for the development of the country. Indian economy is hugely dependent on the agricultural sector. The agricultural culture involves the various activities and weed removal is one of the important amongst other crop production activities. The conventional methods are less effective due to manual operations and hence there was the need of producing the weeding machine. The weeding machines have been developed by the researcher's long back but the problem is with the cost effectiveness of the machines. The cost effective weeding will help the farmers of the countries like us. The machines for weeding will help for the effective working and reduces the efforts of the workers for the task. Authors have presented the design and development of the mechanical weeding machines and its performance from the perspective of utilization in Indian conditions

Design, Analysis and Optimization of Brake Disc Made of Composite Material for a Motor Cycle

The most important component in vehicle is suspension system which directly affects the safety performance and noise level. Suspension arm is one of the most important components in the suspension system. It is fitted in various types of the suspensions like Macpherson wishbone or double wishbone suspensions. The lower control arm is a wishboneshaped metal strut that attaches the wheel to the vehicles frame. In order to determine the deformation and stress distribution in the current design the finite element analysis is carried out. The baseline model of the lower control arm is created by using solid modeling software viz. CATIA. ANSYS Workbench is used for Finite Element Analysis This study deals with Finite Element Analysis of the Lower control arm of Mac pherson suspension system
