本書重點介紹基于SolidWorks軟件進行機構數字仿真分析的思路和方法，主要包括基于Motion插件的運動學、動力學仿真分析以及基于Simulation插件的結構有限元分析。
本書采用項目驅動方式，以項目為載體，融合數字仿真的相關理論和技術。每個項目都包含項目說明、預備知識、項目實施和項目總結，讀者可通過實踐完成學習過程。全書的20個項目是圍繞機械設計行業(yè)的需要，對典型任務做適當簡化編寫而成的，具有較好的應用示范作用。
本書可作為應用型本科及高職高專院校機械類專業(yè)的教材，也可作為企業(yè)技術人員的參考用書。
數字仿真技術是一種基于計算機構建產品虛擬樣機，并實施仿真分析、性能測試及優(yōu)化設計等工作的現代開發(fā)技術。數字仿真能有效地幫助設計者在開發(fā)階段及時了解產品的各種性能，并及時改進，減少試驗次數，顯著提高產品設計質量，縮短開發(fā)周期。目前，機械行業(yè)相關企業(yè)已經廣泛地應用數字仿真技術來提升自身競爭力，其中以機構運動學、動力學仿真技術以及有限元分析技術應用得最為普遍。前者主要用于機械整體傳動機構的方案和尺寸的設計驗證，后者主要用于結構強度、剛度等指標的校核以及結構尺寸的優(yōu)化等。
本書采用項目驅動方式，重點介紹基于SolidWorks 的機械運動學、動力學仿真以及有限元分析技術。全書圍繞自動化機械設計崗位的典型工作任務和內容，具體選擇20 個項目作為載體，將數字仿真分析的相關理論知識和操作方法一起融合在項目的實施過程中，突出技術的應用價值。
本書主要面向工科類應用型本科、高職高專院校的學生以及企業(yè)技術人員。首先，工科專業(yè)不少主干課程都建立在數理基礎上，具有較強的抽象性，學習難度較大，如“機械設計基礎”“工程力學”等。數字仿真技術借助其豐富的可視化手段，可以將抽象的事物轉化為直觀形象的形式，便于學生觀察和理解。其次，在學習專業(yè)課程時，由于實踐教學條件所限，缺乏開展設計實踐的機會，學生缺少直觀感受，也缺乏成就感�；跀底址抡婕夹g開展設計實訓，能讓學生大膽創(chuàng)新，將自己的想法變?yōu)榫唧w直觀的動態(tài)模型，不僅強化了實踐教學，還能帶給學生成就感，從而激發(fā)學習興趣。
最后，在產業(yè)轉型升級下，企業(yè)也在廣泛地使用數字仿真技術提高設計工作效率和質量，因此，掌握數字仿真技術對于更好地適應工作崗位也是非常有必要的。
本書是廣東省第一批品牌專業(yè)建設成果。廣東機電職業(yè)技術學院機械設計與制造專業(yè)對接自動化機械制造業(yè)，將數字技術貫穿專業(yè)課程體系，構建了虛實結合的教學模式。本書基于六年的教學改革實踐，通過校企合作編寫而成。全書共有20 個項目，其中鮑仲輔編寫項目1~ 項目18，曾德江編寫項目19，林澤生編寫項目20，李明為本書提供了企業(yè)案例，陳梓龍負責書中案例的建模和數據處理工作。
本書以講解仿真技術為主，限于篇幅，建模技術不做過多講解，因此需要讀者熟練掌握SolidWorks 的建模操作，特別是自頂向下的建模方法。限于編者水平，書中難免有疏漏和不足之處，敬請讀者批評指正。
