本文作者从膜片弹簧受力变形后内部应力分布着手,分析了膜片弹簧早期弹力衰减的原因。根据膜片弹簧工作过程中应力分布及变化规律,得到了强压时膜片弹簧变形量数值和强压所需次数,试验结果证实了结论的正确性。
The author starts from the internal stress distribution after diaphragm spring force deformation, and analyzes the reason why diaphragm spring attenuates early. According to the stress distribution and variation law of diaphragm spring, the deformation value of diaphragm spring and the number of times required for strong compression are obtained. The test results confirm the correctness of the conclusion.
