摘要

用轻质高强的钛合金弹簧取代传统的钢弹簧以便减重，这不仅要满足弹簧的使用寿命要求，而且要满足弹簧三向刚度及安装空间的要求。理论计算和试验均表明：钛合金弹簧三向刚度及安装空间可与原钢弹簧一致，疲劳寿命≥ 200 万次，加工工艺也与原钢弹簧类似，只是具体控制指标有所差异，完全可以取代钢弹簧。

Abstract

The traditional steel spring is replaced with high-strength and light-weight titanium alloy spring for weight loss, which not only need meet the requirements of the service life of the spring, but also meet the spring requirements of three-way stiffness and installing space. The theoretical calculations and tests showed that : the three-way stiffness and installing space of the titanium alloy spring could be consistent with the original steel spring; The fatigue life of the titanium alloy spring exceeded 2 million times; The processing was also similar to the original steel spring, just different in specific control index. The titanium alloy spring could replace steel spring absolutely.
