MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202541125130 A) filed by Nandha Engineering College, Erode, Tamil Nadu, on Dec. 11, 2025, for 'pneumatic spring stiffness testing machine.'
Inventor(s) include S Balakrishnan; L Elango; V Jaipraveen; and S Sanjay.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a pneumatic spring stiffness testing apparatus designed for measuring the load-deflection characteristics of pneumatic or mechanical springs, shock absorbers, and linear compression components. The apparatus comprises a rigid support frame on which two oppositely oriented pneumatic cylinders are mounted in a linear alignment. The cylinders are actuated to apply controlled compressive or tensile forces on a test specimen positioned centrally between them. The system incorporates adjustable fixtures for securely holding the specimen, ensuring axial alignment during testing. When pressurized air is supplied, the cylinders generate a measurable displacement and force, enabling accurate determination of stiffness, deformation behavior, and performance under variable loading conditions. The invention provides a simple, low-cost, and reliable test platform offering improved repeatability and ease of operation compared to conventional mechanical testing machines. It is particularly suitable for laboratory use, industrial component evaluation, and rapid prototyping environments."
