本書重點介紹基于SolidWorks軟件進(jìn)行機(jī)構(gòu)數(shù)字仿真分析的思路和方法，主要包括基于Motion插件的運動學(xué)、動力學(xué)仿真分析以及基于Simulation插件的結(jié)構(gòu)有限元分析。
本書采用項目驅(qū)動方式，以項目為載體，融合數(shù)字仿真的相關(guān)理論和技術(shù)。每個項目都包含項目說明、預(yù)備知識、項目實施和項目總結(jié)，讀者可通過實踐完成學(xué)習(xí)過程。全書的20個項目是圍繞機(jī)械設(shè)計行業(yè)的需要，對典型任務(wù)做適當(dāng)簡化編寫而成的，具有較好的應(yīng)用示范作用。
本書可作為應(yīng)用型本科及高職高專院校機(jī)械類專業(yè)的教材，也可作為企業(yè)技術(shù)人員的參考用書。
數(shù)字仿真技術(shù)是一種基于計算機(jī)構(gòu)建產(chǎn)品虛擬樣機(jī)，并實施仿真分析、性能測試及優(yōu)化設(shè)計等工作的現(xiàn)代開發(fā)技術(shù)。數(shù)字仿真能有效地幫助設(shè)計者在開發(fā)階段及時了解產(chǎn)品的各種性能，并及時改進(jìn)，減少試驗次數(shù)，顯著提高產(chǎn)品設(shè)計質(zhì)量，縮短開發(fā)周期。目前，機(jī)械行業(yè)相關(guān)企業(yè)已經(jīng)廣泛地應(yīng)用數(shù)字仿真技術(shù)來提升自身競爭力，其中以機(jī)構(gòu)運動學(xué)、動力學(xué)仿真技術(shù)以及有限元分析技術(shù)應(yīng)用得最為普遍。前者主要用于機(jī)械整體傳動機(jī)構(gòu)的方案和尺寸的設(shè)計驗證，后者主要用于結(jié)構(gòu)強(qiáng)度、剛度等指標(biāo)的校核以及結(jié)構(gòu)尺寸的優(yōu)化等。
本書采用項目驅(qū)動方式，重點介紹基于SolidWorks 的機(jī)械運動學(xué)、動力學(xué)仿真以及有限元分析技術(shù)。全書圍繞自動化機(jī)械設(shè)計崗位的典型工作任務(wù)和內(nèi)容，具體選擇20 個項目作為載體，將數(shù)字仿真分析的相關(guān)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(shù)的應(yīng)用價值。
本書主要面向工科類應(yīng)用型本科、高職高專院校的學(xué)生以及企業(yè)技術(shù)人員。首先，工科專業(yè)不少主干課程都建立在數(shù)理基礎(chǔ)上，具有較強(qiáng)的抽象性，學(xué)習(xí)難度較大，如“機(jī)械設(shè)計基礎(chǔ)”“工程力學(xué)”等。數(shù)字仿真技術(shù)借助其豐富的可視化手段，可以將抽象的事物轉(zhuǎn)化為直觀形象的形式，便于學(xué)生觀察和理解。其次，在學(xué)習(xí)專業(yè)課程時，由于實踐教學(xué)條件所限，缺乏開展設(shè)計實踐的機(jī)會，學(xué)生缺少直觀感受，也缺乏成就感�；跀�(shù)字仿真技術(shù)開展設(shè)計實訓(xùn)，能讓學(xué)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(qiáng)化了實踐教學(xué)，還能帶給學(xué)生成就感，從而激發(fā)學(xué)習(xí)興趣。
最后，在產(chǎn)業(yè)轉(zhuǎn)型升級下，企業(yè)也在廣泛地使用數(shù)字仿真技術(shù)提高設(shè)計工作效率和質(zhì)量，因此，掌握數(shù)字仿真技術(shù)對于更好地適應(yīng)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(shè)成果。廣東機(jī)電職業(yè)技術(shù)學(xué)院機(jī)械設(shè)計與制造專業(yè)對接自動化機(jī)械制造業(yè)，將數(shù)字技術(shù)貫穿專業(yè)課程體系，構(gòu)建了虛實結(jié)合的教學(xué)模式。本書基于六年的教學(xué)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(fù)責(zé)書中案例的建模和數(shù)據(jù)處理工作。
本書以講解仿真技術(shù)為主，限于篇幅，建模技術(shù)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。
