What is 3D SSPP™?

The 3D Static Strength Prediction Program™ (3D SSPP) software, originally developed by the University of Michigan, predicts static strength requirements for tasks such as lifting, pressing, pushing, and pulling. The program provides an approximate job simulation that includes posture data, force parameters and male/female anthropometry. The output consists of ten reports that include predicted low-back compression forces, the percentage of the population that have the strength to perform a prescribed job, and data comparisons to the National Institute of Occupational Safety and Health (NIOSH) guidelines. Users can analyze torso twists and bends and make complex hand force entries.  The software has an automatic posture generation feature and 3D human graphic illustrations.

How is 3D SSPP  Used?

3D SSPP is most useful in the analysis of the “slow” movements in heavy material handling tasks. These tasks can be evaluated by breaking the activity down into a sequence of static postures and analyzing each individual posture.  3D SSPP assumes the analyst understands the application of the NIOSH design and upper limit criteria for strength and disc compression forces. The program should not be used as the sole determinant of worker strength performance or job designs based on that performance. Other criteria and professional judgement are required to properly design a safe and productive job.

History of 3D SSPP

3D SSPP is based on more than 50 years of research by ergonomics pioneer Don Chaffin, PhD. He and his colleagues founded the University of Michigan’s Center for Ergonomics and began licensing the product in 1997. Over 3,000 users have licensed the software, making 3D SSPP one of the most impactful software programs ever distributed by the University.  Exclusive rights to the software and underlying intellectual property were acquired by VelocityEHS in October 2020.



Advantages and Application

The 3D Static Strength Prediction Program™ (3D SSPP) is an effective way to analyze the biomechanics and safety of manual materials handling. The software allows users to predict static strength requirements for common manual tasks and make rapid, simple improvements to ergonomic conditions that improve the safety, productivity, and quality of life of your employees.
