简介:锻模的三维造型是锻模CAD/CAM/CAE一体化的基础,但是锻模型腔的设计工艺参数(如拔模斜度、过渡圆角和分模面)常常可变,工艺形状所要求的光滑过渡的曲面数目也较多,因而增加了三维造型的复杂性。下文以DELCAM的POWERSHAPE软件为基础,介绍了汽车曲轴、连杆、转向节、前轴等的三维造型方法。
简介:不久前,瑞森尼科照明系统技术有限公司微博上发出题为“广东将所有路灯改为LED路灯将是灾难!——致广东省政府公开信”。此信一出,立刻在网上引起“万人围观”,也在业界引起了震动。写信人从节能、路灯的环境温度、穿雾能力、抗震能力等众多因素进行了分析,对广东省大力推广LED路灯的做法提出了质疑。用LED路灯大规模替代高压钠灯,愿望是好的。但就目前技术而言,大部分模组式路灯质量尚不过关,应循序渐进。LED路灯要处理好与传统照明的关系,即首先要发扬传统路灯的优点,再加上自己的优点,经过科学的实践不断完善,才能发展为新一代照明电器。割裂与传统照明的关系,甚至另起炉灶、排斥传统照明的作法是不可取的;同时,单纯为了节能与过分追求节能利益、急功近利而忽视照明质量的作法也行不通。广州市人大代表曾经质疑广州市政府LED路灯造价高、质量差与死灯率高:如今,企业发出微薄仍然提出质疑。看来,到了有关部门反思的时候了。反思什么?反思指导思想,反思LED技术路线、反思是否按科学发展观办事。
