Challenge

DRDL required accurate measurement of mass properties of flying objects for effective control of flight in motion. For complex assemblies, manual calculations are not accurate and CAD modeling of smaller details including electronics, harnessings, pneumatics and details of procured parts is difficult in software. Non-homogeneity of materials and uncertainty in dimensions cannot be accounted for in manual calculations and CAD softwares.

 

Timetooth was commissioned with the challenge of designing a specific machine for accurate measurement of mass properties including Centre of Gravity and Moments of Inertia.

Service Area

Turnkey New Product Development

Timeline

January 2019 to December 2019

The final design was a compact machine with leveling and safety features and fixtures to accommodate various shape and size objects.

Key Engineering Solutions

1. Timetooth leveraged virtual simulations for static and dynamic behaviour predictions of machine and object assembly.

2. Design and selection of high resolution and accuracy sensors and data acquisition systems was executed.

3. Industrial grade display system was configured and custom software was developed.

Solutions

Timetooth initiated the project with study of the object followed by conceptualising the machine configurations. Further machine design calculations and error sensitivity analysis was done. Timetooth leveraged virtual simulations for Static and Dynamic behaviour predictions of machine and object assembly.

Concurrently, design and selection of high resolution and accuracy sensors and data acquisition systems was executed. Industrial grade display system was configured and Custom software was developed. The final design was a compact machine with leveling and safety features and fixtures to accommodate various shape and size objects. Manufacturing was carried out with controlled GD & T and conformance to rigorous quality management systems. The machines were inspected using Coordinate-measuring machines and extensive calibration and testing was carried out before final dispatch.

Timetooth team completed the installation and commissioning on site with live object measurement trials ensuring complete customer satisfaction.
