ANALYSING TIPPER STABILITY

It is estimated that there are 900 tipper roll-overs per year in the UK. This article presents the results of an investigation by the West of England University into tipper stability and various factors influencing it. The research was done in collaboration with three companies, and sponsored by the Department of Trade and Industry. The research team has: (1) determined the mechanisms of tipper overturning; (2) developed a computer program simulating tipper action; (3) collected experimental data on the strength and flexibility of individual elements of tippers; (4) recommended how to improve the situation. Tippers roll over because of non-symmetrical loads, which can be caused by a side slope, eccentric load, or even a side wind. To a first approximation, a linear system can be assumed, and the load can be divided into uniform load and torque. The torque leads to overturning, and the angle of deflection is doubled if the torque doubles. The limit of stability can be determined by calculation. A more complicated three-dimensional model, which includes additional features, has been developed and incorporated into a computer program. An appendix to the article outlines the mathematics used in the simplified model.
