Picture of Original Slide Arm Design
Finite Element Analysis was our roadmap to redesigning the slide arm. High stress areas of tension and compression were revealed and targeted as areas requiring additional material to increase the slide arm strength. Immediately the lack of radii and threaded holes were noted as stress concentration areas. The highest stresses occurred in compression surrounding the roller pin. The next highest stresses occurred in tension in the inner wall. Note that the original slide arm experiences 2.34x105psi maximum stress under the operating load of 7,000lbs.
