ADAMS在重载汽车驾驶室振动分析和结构评价中的应用

摘要

在静态加载的情况下可测得重型卡车驾驶室的载荷分布,测试目的是减少驾驶室的振动.在初步模拟时,使用ADAMAS振动模块的模型,结果显示地板的振动与其前横梁的刚度密切相关.利用有限单元法进行加载受力分析结果显示:载荷分布在前横梁有一定的不连续性和不均匀性,振动降低了前横梁的刚度.%Heavy truck cab load distribution may be measured in the case of static loading.Test results are intended to reduce the vibration of the cab.Using the ADAMAS vibration module in the preliminary simulation model,the results show that the stiffness of the vibration of the floor with its front beam is closely related.Using the finite element method for the loading force analysis,the results show the load distribution to the front cross member has a certain discontinuity and unevenness,and the vibration can reduce the stiffness of the front beam.
