Examples
- In this paper , ackerman steering linkage of double - wishbone suspension is taken as the study object , choosing the splitting joint and steering lever joint to carry out the design of optimization the mathematics models are established based on the multi - body system dynamics , applying its analysis method of kinematics to study the mechanism kinetic principles owing to more spatial factors considered , and calling off many hypotheses affecting the accuracy , compared with the traditional methods , the models are better to reflect the realistic motion principles , the results are more exact and applicable moreover , the force analysis is applied to the conduct mechanism the analysis method of dynamics in the multi - body dynamics is applied to study the forces applied on every component , working out the constraint reaction force of up and down ball joints , and developing the current computation program in the end , produce the upper wishbone geometry model in the ansys software package , meshing and carrying out the fea , testifying if the intensity of the wishbone meet with the requirements
本文以双横臂独立悬架的转向传动机构作为研究对象，选择对断开点和节臂球销的位置进行优化设计，在此基础上建立了基于多体系统动力学的导向机构和转向传动机构的数学模型，运用该学科的运动学分析方法研究机构的运动规律，编制了通用优化设计软件。由于考虑了更多的空间因素，取消许多影响准确性的假设，因此建立的数学模型与传统的方法相比更能反映实际运动规律，得到的优化结果也更加精确实用。此外，本文还针对导向机构进行受力分析，在建立该机构的空间动力学模型后，运用多体动力学中的动力学分析方法研究各个杆件的受力，计算出上下球铰的约束反力，并开发出了相应的通用计算程序。
