摘要
超塑成形/扩散连接是一种先进的钛合金制造技术,采用该技术,4层结构的钛合金产品表面存在沟槽问题,对某气动面表面沟槽的成因和对强刚度的影响进行了浅析,评估了表面沟槽对该产品强刚度的影响水平。
SPF/DB is an advanced manufacturing technology for titanium alloy, there are grooves on the surface of the products with four layers of structure,this paper not only analyzed the cause and effect of the groove on the aerodynamic surface and control surface, but also evaluated the effect size of strength and stiffness to the product.
