Cutting the Cost of Lawn Mower Redesign with Abaqus and fe-safe Ariens reduces part count, improves durability of their next-generation zero-turn machine
Ariens engineers were tasked with a redesign of their Gravely brand zero-turn commercial lawn mower. They wanted to design the mower as efficiently as possible to cut manufacturing costs and increase fuel efficiency. Simulation would be necessary to deliver an upgraded mower that met these goals on time.
Dassault Systèmes Response
Ariens engineers used Abaqus/CAE and fe-safe from Dassault Systèmes SIMULIA, along with Wolfstar Technologies’ True-Load, to locate and accurately model strain gauges in all areas of the lawn mower, enabling weld elimination, part-count reduction, fatigue life improvement and other design enhancements.
Part count of the mower frame was reduced by 50%. Testing time and costs were cut. When the new mower went through final field tests, Ariens engineers’ confidence in their simulations was supported by performance. Abaqus’ visualization tools also helped engineers communicate better with designers and upper management.
