摘要
目前,国内缺少滑雪板固定器检验调整设备。设计了一种测试滑雪板固定器脱离力矩的装置,可实现共体夹持-分时加载的测试模式。针对固定器受力进行理论分析,研究滑雪板固定器的失效机理,并以此设计脱离力矩测试装置。在试验样机上进行50次脱离力矩测试试验,通过正态分布检验、拉依达准则和标准值偏差验证,证明装置试验数据具有有效性、稳定性和分散性。结果表明:脱离力矩测试装置能够稳定测量滑雪板固定器的脱离力矩,可为固定器生产商及滑雪板租赁商提供可靠的测试参数。
Currently,there is a lack of equipment for testing and adjusting ski bindings in China.A device was designed to test the disengagement torque of ski bindings,implementing a common clamping-timed loading test mode.Firstly,a theoretical analysis of the forces acting on the ski binding was performed to study the failure mechanism of the ski binding,and a disengagement torque test device was designed accordingly.Fifty disengagement torque tests were conducted on the test prototype,and the validity,stability,and dispersion of the experi-mental data from the device were verified through normal distribution tests,the Pauta Criterion,and standard deviation verification.The results indicate that the disengagement torque test device can reliably measure the disengagement torque of ski bindings,providing valuable test parameters for binding manufacturers and ski rental companies.
