The Water Handling Debottlenecking Project team has, instead, made use of a different technology—employing a Self-Propelled Modular Transporter (SPMT) to install nine vessels in situ. These SPMT units have many advantages over crane installations, such as safety and efficiency, not to mention lower costs due to their self-propelled capabilities.展开更多
自行式模块化运输车(Self-Propelled Modular Transporter,SPMT)运输浮式生产储卸油装置(Floating Production Storage and Offloading,FPSO)上部模块经过减速带时由于激励而产生振动。参考四分之一车辆振动简化模型建立SPMT振动模型和...自行式模块化运输车(Self-Propelled Modular Transporter,SPMT)运输浮式生产储卸油装置(Floating Production Storage and Offloading,FPSO)上部模块经过减速带时由于激励而产生振动。参考四分之一车辆振动简化模型建立SPMT振动模型和多自由度系统动力学方程。采用MATLAB软件中Simulink模块对路面激励下的悬架液压系统加速度响应进行仿真模拟,得到加速度响应谱。与文献[11]提出的最大加速度响应谱进行对比,验证模型正确性。通过仿真分析得到SPMT在不同悬架阻尼、行驶速度、减速带宽度下通过减速带时模块和轮胎的加速度,分析不同参数对运输过程中加速度的影响。展开更多
