Analysis of Rack and Pinion under dynamic conditionsnagaraju kondrasi
Based on physical and thermal properties graphite cast iron has got more strength than sand cast Mg alloy and it is clear from the results that the load carrying capacity of former is larger than the later. Hence Graphite cast iron is preferred for the manufacture of rack and pinion.
In static structural analysis the total deformation and von - mises stresses are more in sand cast Mg alloy than graphite cast iron. Hence graphite cast iron has better strength than Sand cast Mg alloy.
In modal analysis the number mode shapes are higher for graphite cast iron than sand cast Mg alloy.
Under transient conditions the total deformation of Graphite CI is less than that of Sand cast mg alloy. Hence former is preferred under Transient conditions.
Under fatigue loads the damage is more in sand cast Mg alloy. Hence graphite CI is preferred for manufacturing of Rack and pinion.
Hence Keeping all the analysis in view the graphite cast iron is preferred over sand cast Mg alloy.

SELECTION OF GEAR BOX FOR VARIOUS MECHANICAL SYSTEMSANDIP THORAT
Automotive gearboxes are used to reduce load on the engine by manipulating torque and speed. They have the option to select one of several different gear ratios.
Once the engine has reached a number of revolutions per minute, it is advisable to increase the gear to reduce the engine rpm to reduce wear on the engine, allow more control, and greater speeds, better acceleration, and better fuel economy.
Automotive gearbox also have the provision to do the opposite ie provide an increase in output shaft speed with a reduction of torque.
Most gearboxes are used to increase torque & reduce the speed of a output shaft. This produces a mechanical advantage .

Topology Optimization for Additive Manufacturing as an Enabler for Robotic Ar...piyushsingh376
The current research is intended to minimize the mass of T shaped joint by using lattice structure and topological optimization tool.
The stresses, deformation, safety factor of generic and optimized design is evaluated on the basis of these mentioned parameters. The findings have shown that topological optimization method is best as compared to lattice structure method for weight minimization.
A Coordinate measuring machine is an electromechanical system design to perform coordinate metrology.
CMMs are also considered as transducers that can convert physical measurements into electrical signals.
They are versatile in their capability to record measurement of complex profiles with high sensitivity (0.0025 mm) and speed.
