型钢大师 vs Mechanical Engineering Toolkit

【简介】 帮助工程师迅速查询型材几何尺寸和力学特性的工具类应用。 本软件的型材涵盖了热轧型钢、热轧钢棒(方钢、圆钢等)、冷弯薄壁型钢、钢管、钢板、钢筋、钢轨、钢丝绳等各类定型化的钢材和钢构件。查询内容包含截面尺寸、单位重量、惯性矩、惯性半径、截面模数、重心距离、外表面积等，数据准确可靠，可以为钢结构的设计和计算提供参考依据。 软件支持近20种截面自定义计算，包括常用的圆钢管、方钢管；非标的工字钢、槽钢、角钢；焊接的箱型、盒式、十字形截面等。 此外它还可以根据型材的类型和长度计算出型材总重量，方便钢材加工厂商的现场订货。各项参数均可以在软件内部方便地进行单位换算。 高级功能包括： （1）快速查询功能：直接搜索定位到某一型材； （2）收藏功能：收藏常用型材信息，方便随时查阅； （3）计算功能：计算型材重量、长细比以及惯性矩移轴； （4）近20种非标及焊接型材自定义计算，让您计算任意尺寸的型材； （5）特殊模块：解锁一些比较特殊的型材截面。 注：高级功能一次买断，购买后不再收取相关费用。 数据来源于最新的国家规范和行业标准，除了钢板，所有的数据都是根据最新的国标文件，全部由手写输入。无论是标识符号还是小数位精度，所有的数据的格式均与规范保持一致，保证数据的绝对可靠。“型钢大师”适用于每一个与钢材打交道的工程师，无论您是土建领域的工程师、钢铁五金专业的工程人员，还是机械、船舶、石油化工方面的从业者。 微信公众号：结构大师工作室 官方微博：结构大师V 联系邮箱：structuremaster@163.com

Mechanical Engineering Toolkit is a professional engineering calculator for students, researchers, and practicing engineers. Choose a formula, enter your variables, and get instant results — with calculation steps, formulas, diagrams, and unit conversions shown along the way. Switch between SI and Imperial units anytime, save favorites, and find the right tool fast with recommendations by major. Save your inputs as named projects, and export any result as text, image, CSV or PDF.
