汽車(chē)

大

機(jī)械千斤頂是提升重型設(shè)備的裝置。最常見(jiàn)的樣式是轎車(chē)千斤頂，地板千斤頂、車(chē)庫(kù)千斤頂，用以提升汽車(chē)，以方便維修。轎車(chē)千斤頂通常借助機(jī)械優(yōu)勢(shì)讓一個(gè)人就可提升汽車(chē)。更強(qiáng)大的千斤頂使用液壓動(dòng)力可以提供更遠(yuǎn)距離的舉升。機(jī)械千斤頂通常以最大提升能力分級(jí)（例如1.5噸或3噸等）32￡2

裝配體運(yùn)動(dòng)（可在S

olidWorks核心包內(nèi)使用）。您可使用裝配體運(yùn)動(dòng)來(lái)動(dòng)畫(huà)裝配體的運(yùn)動(dòng)：添加馬達(dá)來(lái)驅(qū)動(dòng)裝配體一個(gè)或多個(gè)零件的運(yùn)動(dòng)。使用設(shè)定鍵碼點(diǎn)在不同時(shí)間規(guī)定裝配體零部件的位置。裝配體運(yùn)動(dòng)使用插值來(lái)定義鍵碼點(diǎn)之間裝配體零部件的運(yùn)動(dòng)。

物理模擬（可在S

olidWorks核心包內(nèi)使用）。您可使用物理模擬在裝配體上模仿馬達(dá)、彈簧、碰撞、以及引力。物理模擬在計(jì)算運(yùn)動(dòng)時(shí)考慮到質(zhì)量。物理模擬計(jì)算相當(dāng)塊，所以您可將之用來(lái)生成使用基于物理的模擬的演示性動(dòng)畫(huà)。

COS

MOS

Motion屬性中的精度設(shè)定。

2.如果模型中的零件快速移動(dòng)，經(jīng)常評(píng)估雅可比值。

3.機(jī)制可能已鎖定。以不同的初始配置開(kāi)始模擬或者更改您的馬達(dá)以獲得有效的運(yùn)動(dòng)。

4.如果在模擬開(kāi)始時(shí)就出現(xiàn)故障，使用較小的初始積分器步長(zhǎng)大小。

5.嘗試使用一嚴(yán)格解算器，如'WS

TIFF'。

6.嘗試在模型中避免激烈斷續(xù)性，如突然運(yùn)動(dòng)變化，力變化或啟用/禁用配合。

7.您可能在使用速度極高的馬達(dá)。嘗試降低馬達(dá)速度。

8.確定任何時(shí)候只有一個(gè)馬達(dá)在驅(qū)動(dòng)某一零部件。47￡2
