1、了解升降平臺模型，并記錄其編號。分析機(jī)械的實(shí)際構(gòu)造和運(yùn)動情況，查明該機(jī)構(gòu)由多少個構(gòu)件組成，找出機(jī)架及原動件，并根據(jù)相連接的兩構(gòu)件間的接觸情況及相對運(yùn)動的性質(zhì)，確定各個運(yùn)動副的類型，并依次標(biāo)上字母。
Learn lifting platform model, and record its number. The actual construction and analysis of mechanical movement, identify the agency by the number of components that identify the rack and the original moving parts, and the nature of the exposure and the relative motion of the two components are connected between each deputy campaign to determine the type, and sequentially labeled with letters.  

2、確定構(gòu)件數(shù)目，將升降平臺摸型緩慢地運(yùn)動，從原動件開始，沿著運(yùn)動的傳遞路線依次在各構(gòu)件上標(biāo)上數(shù)字編號。循著運(yùn)動的傳遞路線分析該機(jī)械原動部分的運(yùn)動如何經(jīng)過傳動部分傳遞到工作部分。
Determine the number of members, the lifting platform slowly to touch-type motion, starting from the original mover, moving along the relay route on each member in turn marked figures. Follow the movement of the transmission line analysis of how the movement of the mechanical moving parts after the original transmission parts delivered to the working part.   

3、仔細(xì)觀察各構(gòu)件間的接觸情況及相對運(yùn)動的特點(diǎn)，用規(guī)定的符號將各運(yùn)動副表示出來，用直線或曲線將同一構(gòu)件上各運(yùn)動副元素連接起來，用箭頭標(biāo)出機(jī)構(gòu)原動件在圖示位置時的運(yùn)動方向，繪制出所要畫的機(jī)構(gòu)運(yùn)動簡圖，選擇與機(jī)械的多數(shù)構(gòu)件的運(yùn)動平面相平行的平面作為繪制機(jī)構(gòu)運(yùn)動簡圖的投影面。
Features and careful observation of the contact condition of the relative movement between the members, with a predetermined symbol vice movements represented by a straight line or a curve motion of each the sub-elements are connected on the same member, indicated by an arrow in FIG original moving parts mechanism position shown in the direction of movement, and draw the kinematic diagram to be drawn, sport plane selection and mechanical components of most parallel kinematic plane as drawn sketch of the projection surface. 

4、 分析升降平臺運(yùn)動的確定性。計算升降平臺的自由度數(shù)，并將結(jié)果與實(shí)際升降平臺的原動件數(shù)相對照，若與實(shí)際情況不符，要找出原因及時改正。
Analysis lifting platform movement certainty. Number of degrees of freedom is calculated lifting platform, the original number of the movable member and the results contrasted with the actual lifting platform, if inconsistent with the actual situation, to find out the reasons for timely correction.

5、選擇適當(dāng)?shù)谋壤撸鶕?jù)該機(jī)械的運(yùn)動尺寸，確定各運(yùn)動副之間的相對位置，
Select the appropriate scale, according to the mechanical motion of size, to determine the relative positions of deputy campaign between
