A servohydraulic test system is requested to determine the dynamic properties of biomedical implants, in particular orthopedic constructs, medical devices and biomaterials, in the load range 5-15KN. The apparatus is fully equipped to perform accurate and repeatable fatigue life studies, and tension, bending, and compression tests of cellular samples and biological tissues, as well to test the durability and wear properties of biomedical components such as knee, hip, and spine implants. The equipment is critical to three research programs pivoting on the development of patented biomedical devices made of lattice materials in accordance to ASTM standards. The apparatus will complement the current testing machines of our department which surprisingly does not own a machine capable of cyclic fatigue testing under low-force regime. The applicant's colleagues of the newly-created Bioengineering lab share the need for such equipment which targets bioengineering applications. Its acquisition is essential to continue the further development of the patented devices as well as for HQP training and completion of graduate student projects related to the supported projects.

需要一个伺服液压测试系统来确定生物医学植入物，特别是骨科结构、医疗器械和生物材料在5-15kn负载范围内的动态特性。该仪器设备齐全，可以进行准确和可重复的疲劳寿命研究，细胞样本和生物组织的拉伸、弯曲和压缩测试，以及测试膝部、髋部和脊柱植入物等生物医学部件的耐久性和耐磨性。该设备对三个研究项目至关重要，这些项目的重点是根据ASTM标准开发由晶格材料制成的专利生物医学设备。该仪器将补充我们部门现有的试验机，令人惊讶的是，我们部门没有能够在低力状态下进行循环疲劳试验的机器。申请人在新创建的生物工程实验室的同事也有同样的需求，即针对生物工程应用的这种设备。它的收购对于继续进一步开发专利设备以及HQP培训和完成与所支持项目相关的研究生项目至关重要。
