数字仿真技术是一种基于计算机构建产品虚拟样机，并实施仿真分析、性能测试及优化设计等工作的现代开发技术。数字仿真能有效地帮助设计者在开发阶段及时了解产品的各种性能，并及时改进，减少试验次数，显著提高产品设计质量，缩短开发周期。目前，机械行业相关企业已经广泛地应用数字仿真技术来提升自身竞争力，其中以机构运动学、动力学仿真技术以及有限元分析技术应用得最为普遍。前者主要用于机械整体传动机构的方案和尺寸的设计验证，后者主要用于结构强度、刚度等指标的校核以及结构尺寸的优化等。
本书采用项目驱动方式，重点介绍基于SolidWorks 的机械运动学、动力学仿真以及有限元分析技术。全书围绕自动化机械设计岗位的典型工作任务和内容，具体选择20 个项目作为载体，将数字仿真分析的相关理论知识和操作方法一起融合在项目的实施过程中，突出技术的应用价值。
本书主要面向工科类应用型本科、高职高专院校的学生以及企业技术人员。首先，工科专业不少主干课程都建立在数理基础上，具有较强的抽象性，学习难度较大，如“机械设计基础”“工程力学”等。数字仿真技术借助其丰富的可视化手段，可以将抽象的事物转化为直观形象的形式，便于学生观察和理解。其次，在学习专业课程时，由于实践教学条件所限，缺乏开展设计实践的机会，学生缺少直观感受，也缺乏成就感。基于数字仿真技术开展设计实训，能让学生大胆创新，将自己的想法变为具体直观的动态模型，不仅强化了实践教学，还能带给学生成就感，从而激发学习兴趣。
最后，在产业转型升级下，企业也在广泛地使用数字仿真技术提高设计工作效率和质量，因此，掌握数字仿真技术对于更好地适应工作岗位也是非常有必要的。
本书是广东省第一批品牌专业建设成果。广东机电职业技术学院机械设计与制造专业对接自动化机械制造业，将数字技术贯穿专业课程体系，构建了虚实结合的教学模式。本书基于六年的教学改革实践，通过校企合作编写而成。全书共有20 个项目，其中鲍仲辅编写项目1~ 项目18，曾德江编写项目19，林泽生编写项目20，李明为本书提供了企业案例，陈梓龙负责书中案例的建模和数据处理工作。
本书以讲解仿真技术为主，限于篇幅，建模技术不做过多讲解，因此需要读者熟练掌握SolidWorks 的建模操作，特别是自顶向下的建模方法。限于编者水平，书中难免有疏漏和不足之处，敬请读者批评指正。
