In an effort to improve the ride comfort and tyre and chassis life on large dump trucks a computer model of the vehicle was developed. This indicated that substantial improvements could be achieved by reducing friction in the front sliding-pillar struts and by actively controlling suspension forces. Concept designs for active and semi-active suspensions were generated, analysed and optimised using our vehicle model. In conjunction with our client, Birrana Engineering, the design has now been progressed to production representative stage and extensive field testing has confirmed the benefits of the system. This project is a great example of how expertise in control systems, electronics, software, hydraulics and mechanical design in one dedicated project team can deliver great results. A patent has been granted for this technology.
