Fig. 2From: Manual wheelchair downhill stability: an analysis of factors affecting tip probabilityDiagram of wheelchair model. Variations were made to the wheelchair seat angle, backrest angle, rear axle position and user position (a), as well as user mass, wheelchair speed, ground slope, and bump height in the simulations. The Madymo model is shown on the right (b) Fig. 3 Experimental setup for testing wheelchair downhill stabilityBack to article page
