    摘要:

    根据橡胶减振器相关标准,确定橡胶减振器跨点实验的试验方案,并以此对试验台的主体结构进行设计,同时针对实验台的关键部位即可移动横梁的结构提出两种方案,推导出横梁所需夹紧力的计算公式,计算出夹紧力,为后续夹紧装置的设计提供了依据,并利用有限元分析软件对其进行分析校核。同时对试验台主体结构进行模态分析,得出试验台竖直方向上的固有频率远高于试验台工作时的激振频率,不会发生共振,验证了该试验台结构的可行性。

    Abstract:

    According to relevant standards of rubber shock absorbers, the rubber shock absorber test scheme was determined, and the main structure of the test bench was designed. At the same time, two schemes were proposed for the movable beam, and the formula for calculating the clamping force required for the beam was derived. The clamping force was calculated. These provide basis for the design of the clamping device. Then finite element analysis software was used to make analysis and verification. At the same time, the modal analysis of the main body of the test bench shows that the natural frequency in the vertical direction of the test rig was much higher than the excitation frequency when the test rig was working, and no resonance occurred. The feasibility of the test bench structure is verified.
