A torque wrench is used to tighten bolts and is able to exert the required amount of torque which in many applications is critical. Of many types available the beam type is the simplest which operates using the fact that the maximum deflection of a beam is proportional to the moment applied. So by measuring the deflection the torque can be determined. In this paper a simple beam type torque wrench has been designed primarily using theoretical analysis. Then a CAD model has been prepared and subjected to FEA using ANSYS. The design was optimized by adjusting the dimensions.

The objectives of this project is to designing and optimization of a heavy duty torque wrench using Computer Aided Engineering (CAE) software such as CATIA, ProE etc. and then optimize the design using the FEA tools offered by ANSYS or Hypermesh. The required properties of the final product to be achieved are:
a. Ability to apply a torque of about 500 N-m on a 1 inch nut
b. Easy to use
d. Sturdy enough to be used frequently and repeatedly
f. Simple in design and construction
h. A reasonable safety factor...
