Effects of uneven environmental loads on the operating conditions of layered rubber springs
Abstract
The mechanical properties of layered rubber springs are highly temperature-dependent; therefore, in railway vehicles where such parts are used in running gears, uneven thermal loading may degrade running safety. This study used FEM to assess the effect of solar-induced thermal loading on rubber springs. Results indicate average temperature differences up to 14-15 °C between springs on opposite sides of the vehicle. The results may provide a basis for further analyses of safety against derailment.
