摘　　要：在普通试验机上进行水泥基复合材料的荷载—位移关系全曲线试验,因试验机刚度不能满足试验的要求,需要采取措施增强试验机刚度。本文设计制作了一套压力试验机变形阻尼器,按照该压力试验机变形阻尼器设计原理,可设计出满足不同承载能力及变形能力要求的试验机刚度增强装置。在普通试验机上安装上这种压力试验机变形阻尼器来研究水泥基复合材料的荷载—位移关系全曲线,保证了试验试件在受力过程中实现可靠、稳定的加载过程,从而获得反映材料真实特性的荷载—位移关系全曲线。If the test of load-displacement curves of cement-based composites is made on ordinary testing machine, the stiffness of the machine will not meet the test requirements, so improvement is necessary to strengthen the stiffness. In this paper, a deformation damper was designed. With the damper, the stiffness of test machine can bear varied loads and deformations. As a result, when the above test is made, the loading procedure will be stable and reliable and the load-displacement curves will reflect material properties factually.
