叉车转向桥作为叉车的主要零部件,受多种载荷作用,其强度直接影响整车寿命。采用FORTRAN语言与ANSYSAPDL等语言相结合,开发叉车转向桥零部件的三维有限元分析系统ZXQFEM1,ZXQFEM1设置了与ANSYS程序的接口,使之可以方便自如地调用ANSYS程序。ZXQFEM1系统应用ANSYS中的SOLID92单元,计算表明,该单元适应性好,能较好地模拟叉车转向桥零部件。介绍ZXQFEM1系统的主要功能,ZXQFEM1包括叉车转向桥零部件造型前处理模块和应力变形分析后处理模块,给出包括转向桥壳、转向节、转向销等若干计算实例,成功试制了铸钢转向桥体,设计了新型的转向桥试验台夹具和施力装置等,并进行了相应分析。根据计算合理安排转向桥各零部件结构尺寸,为结构设计和改进提供了可靠依据。
Forklift steering axle forklift as the main components, subject to a variety of loads, the strength of a direct impact on vehicle life. Using the FORTRAN language and ANSYSAPDL language, the 3D finite element analysis system ZXQFEM1 and ZXQFEM1 for the forklift steering axle components are developed to interface with the ANSYS program so that the ANSYS program can be easily and conveniently called. The application of SOLID92 unit in ANSYS ZXQFEM1 system shows that the unit has good adaptability and can well simulate the forklift steering axle components. The main functions of the ZXQFEM1 system are introduced. The ZXQFEM1 includes the parts pre-processing module and the post-processing module of the stress deformation analysis for the forklift steering axle. Several calculation examples including the steering axle housing, steering knuckle and steering pin are given. Body, designed a new type of steering bridge test rig fixture and force device, and carried out the corresponding analysis. According to the calculation, the structural dimensions of each component of the steering bridge are rationally arranged, which provides a reliable basis for structural design and improvement.
