Optimization of Supporting Elasticity of Rubber Floating Slab Tracks by MIGA
摘要
Abstract
The multi-island genetic algorithm (MIGA) combined with ABAQUS was employed to analyze the effect of supporting elasticity on vibration reduction ability of the rubber floating slab tracks. According to Technical code for floating slab tracks (CJJ\T191-2012), vibration reduction ability of the rubber floating slab tracks was optimized with the rubber elasticity as the variable. Results show that (1) There is no linear relation between the supporting elasticity and the optimization target, i.e. reduction of rubber elasticity does not mean to always get the best vibration reduction ability of the rubber floating slab track. For engineering problems, it is suggested to use the optimization method to research the parameters of the rubber floating slab track. (2) When the value of the supporting elasticity of the rubber support is 6.44 × 108N/m2, the best vibration reduction ability of the rubber floating slab track can be reached. The optimized rubber floating slab track has better vibration reduction ability (2.7 dB) than some other type of rubber floating slab tracks.关键词
