摘　　要：球窝一般采用PA66 GF30材料,该材料具有热变形温度高、平衡吸水率低的特点。球窝需要在不同温度下工作,同时承受较大的轴向力。分别对球窝在-40℃、23℃和80℃三种温度下进行ANSYSWorkbench仿真分析,同一种温度分别施加3500 N和施加极限位移量,同时在实验室进行现场模拟。对比仿真分析和实验室模拟结果发现:3500 N轴向力下,不同温度下的最大变形数据相差均小于10%,说明有限元仿真设置正确、合理。23℃温度下,球窝能承受的破坏力最大;-40℃温度下,球窝能承受的破坏力最小,说明低温更容易发生脆性破坏。对于添加玻璃纤维(GF)的塑料材料,通常采用80%的安全系数来界定工程抗拉强度,转换后结果表明抗拉强度同样满足材料对应温度下的许用应力。研究内容对于实际的工程应用具有较高的推广和借鉴意义。The ball socket is generally made of PA66 GF30 material,which is characterized by high heat distortion temperature and low equilibrium water absorption.The ball and socket needs to work under different temperatures and at the same time withstand large axial force.Simulation analysis on ANSYS Workbench is carried out to study the ball socket at three temperatures,-40℃,23℃and 80℃respectively,and at the same temperature,simulation and laboratory tests with 3500 N load and ultimate displacement are both carried out.By comparing the simulation and laboratory results,it is found that:under 3500 N axial force,the difference between the maximum deformation data at different temperatures is less than 10%,which indicates that the simulation is set correctly and reasonably.At 23℃temperature,the destructive force that ball socket can withstand is maximum,and at-40℃temperature,the destructive force that ball socket can withstand is smallest,which indicates that the brittle damage is more likely to occur at low temperatures.For the addition of glass fiber(GF)plastic materials,80%of safety factor is usually adopted to define the tensile strength in project,and the converted results show that the tensile strength also meets the permissible stress at the corresponding temperature of the material.Thus the content of the study is of high significance for the promotion and reference for the practical engineering applications.
