摘要:
首先,基于大型摊铺机车架刚度和强度设计方法,建立大型摊铺机车架的有限元模型.然后,通过模态仿真计算与模态分析得到车架的前10阶固有频率及主要振型,并通过模态实验验证了有限元模型的正确性.最后,提出动静力学特性相结合的综合结构设计方法:以动态刚度为目标函数,通过相对灵敏度分析确定车架刚度薄弱部分,利用拓扑优化手段实现摊铺机车架局部形状的改变及加强筋的布置,以提高车架刚度;结合静力学特性,分析摊铺机车架在静置情况下的应力分布及变形情况,以校验其性能可靠性,最终完成车架结构优化设计.对优化后的车架进行仿真分析,结果表明,优化后车架第1阶和第2阶固有频率明显提高,同时车架质量减少了3%.
Abstract:
The finite element model of the large paver frame is established according to the stiffness and strength design method of it. The first 10 order natural frequencies and main vibration types of the paver frame are obtained through modal simulation calculation and modal analysis. And, the finite element model is verified to be reliable through the frame modal experiment. An integrated structure design method combining dynamic and static mechanical properties is proposed. The weak part of the frame stiffness is obtained by structure sensitivity analysis with dynamic stiffness as structural optimization’s objective. The frame stiffness is increased through the change of local shape and the arrangement of the reinforcing bars achieved by topology optimization. Based on the static analysis, the stress distribution and deformation of the frame in the static condition are analyzed to check the performance and reliability of the frame. Finally, the structural optimization design of the large paver frame is completed. The optimized frame is analyzed. The results show that the first and second order natural frequencies of the frame are improved obviously, and the frame mass is reduced by 3%.
