- Abstract:
- The method of repeated loading test was employed,some factors effect on the temperature dependency of SHDR,such as horizontal strain,vertical pressure,frequency,G value and sequence of temperature loading,were analyzed,the influence of the above factors on the post-yield stiffness,yield strength,hysteretic area of single loop,equivalent stiffness and equivalent damping ratio of SHDR was given,the corresponding formula except horizontal strain were given.The results show that,there is little effect for some factors,such as vertical pressure,loading frequency,G value and the sequence of temperature loading on the bearing,while the strain has a great influence.As a whole,the post-yield stiffness and yield strength of the bearing decrease exponentially with the increase of temperature at room temperature.
