Because of the bolted joints between the elastic body and the pressed body in this kind of load cell, the contact between them will have serious influence on the load cell hysteresis.
Test researches on slip coefficient of high-strength bolted joints with certain rust inhibiting coatings on contact surfaces are reported.
介绍了连接接触面涂醇酸铁红或聚氨酯富锌漆的高强度螺栓连接抗滑移系数试验研究。
