用Mechanica集成模式進(jìn)行結(jié)構(gòu)靜力學(xué)分析一般需要八個(gè)步驟，如果需要進(jìn)行優(yōu)化設(shè)計(jì)還需要定義設(shè)計(jì)參數(shù)并啟動(dòng)敏感度分析和全局優(yōu)化研究。

1.建立幾何模型:在Pro/E中創(chuàng)建幾何模型。
Create the Model Create the part or assembly that satisfies the design intent.

2.理想化模型為劃分網(wǎng)格做準(zhǔn)備。
Idealize the Model Prepare the model for automatic mesh generation. This includes specifying appropriate idealization types and any required idealization properties.

3.為模型設(shè)置單位和材料屬性，在裝配件分析中，可以為不同的零件分配不同的材料屬性。在應(yīng)力分析中，必需的材料特性是楊氏模量和泊松比。
Set Units and Material Properties Specify the appropriate system of units and assign material properties.

4.添加約束，為模擬模型在現(xiàn)實(shí)中的功能，必須設(shè)定模型的約束。定義約束就是限制模型的自由度個(gè)數(shù)。
Identify Constraints Define realistic constraints that simulate how the model will function in the real world.

5.添加載荷，載荷種類有點(diǎn)載荷、邊載荷以及面壓力載荷等。
Set LoadsDefine loads to simulate how the model is loaded in the real world.

6.定義分析任務(wù)，運(yùn)行分析:首先建立分析任務(wù)，然后MECHANICA進(jìn)行錯(cuò)誤檢查，進(jìn)行計(jì)算，生成計(jì)算結(jié)果數(shù)據(jù)和計(jì)算過程信息。
Define the Analysis Define the appropriate analysis type (static,modal, and so on) based on the required results. You can also define the convergence settings.

7.運(yùn)行分析。
Run the Analysis Run the defined analysis.

8.查看結(jié)果，可以顯示變形情況、應(yīng)力分布以及模態(tài)振型等計(jì)算結(jié)果。
View and Interpret the Results, You can generate graphs, fringe plots, and so on to visualize the converged results

下面4步是優(yōu)化設(shè)計(jì)才會(huì)用到

9.定義設(shè)計(jì)參數(shù)，這些參數(shù)能夠反映幾何變化。
Define the Design ParametersCreate Pro/MECHANICA parameters that specify how the model geometry can change.

10. 運(yùn)行敏感度分析，通過該研究可以發(fā)現(xiàn)那個(gè)參數(shù)對(duì)設(shè)計(jì)目的影響最大(主要參數(shù))，如對(duì)應(yīng)力，變形的影響。
Run Sensitivity Studies Perform sensitivity studies on the parameters defined in the previous step. This will help you decide which parameters have the most influence on the design.

11.啟動(dòng)全局優(yōu)化，確定主要參數(shù)的值或其范圍。
Run the Optimization Specify a goal, design constraints, and parameter ranges that constrain the solution boundaries.

12.根據(jù)優(yōu)化結(jié)果(要參數(shù)的值或其范圍)，通過更改參數(shù)來更新模型。
Update the ModelYou can automatically or manually update the Pro/ENGINEER model.
