摘要
考虑车架的弹性特性,将电流变效应与液压悬置技术相结合,建立电流变液动力总成悬置系统的数学模型,运用MATLAB软件的Simulink模块对模型的典型工况进行仿真分析,得出在无电场和施加电场情况下的动力总成系统及车架的位移和加速度响应特性曲线。通过电流变液动力总成悬置系统隔振特性模拟试验台进行模拟实验,验证了仿真模型的正确性,仿真和试验数据说明在施加电场条件下,电流变液动力总成悬置系统较无电场作用下的隔振性能优越。
By considering the elasticity characteristics of vehicle frame, let the electro-rheologic effect be combined with the hydraulic suspension technology to establish the mathematic model of the electro-theologic liquid power assembly suspension system. By Utilizing the Simulink module of MATLAB software to carrying out simulative analysis on the typical working conditions of model to obtain the characteristic curves of power assembly system, of displacement of vehicle frame and of the acceleration response. By means of the simulation test-bed of the vibration-insulation characteristics of electro-rheologic liquid power assembly suspension system to carrying out the simulative experiment thus verified the correctness of the simulation model. The simulation and data of experiment explained that under the exertion of electric field, the vibration-insulation performance of electro-theologic liquid power assembly suspension system is superior to those of the suspension system with out the effect of electric field.
