1、了解升降平臺模型，并記錄其編號。分析機械的實(shí)際構造和運動(dòng)情況，查明該機構由多少個(gè)構件組成，找出機架及原動(dòng)件，并根據相連接的兩構件間的接觸情況及相對運動(dòng)的性質(zhì)，確定各個(gè)運動(dòng)副的類(lèi)型，并依次標上字母。
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、確定構件數目，將升降平臺摸型緩慢地運動(dòng)，從原動(dòng)件開(kāi)始，沿著(zhù)運動(dòng)的傳遞路線(xiàn)依次在各構件上標上數字編號。循著(zhù)運動(dòng)的傳遞路線(xiàn)分析該機械原動(dòng)部分的運動(dòng)如何經(jīng)過(guò)傳動(dòng)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、仔細觀(guān)察各構件間的接觸情況及相對運動(dòng)的特點(diǎn)，用規定的符號將各運動(dòng)副表示出來(lái)，用直線(xiàn)或曲線(xiàn)將同一構件上各運動(dòng)副元素連接起來(lái)，用箭頭標出機構原動(dòng)件在圖示位置時(shí)的運動(dòng)方向，繪制出所要畫(huà)的機構運動(dòng)簡(jiǎn)圖，選擇與機械的多數構件的運動(dòng)平面相平行的平面作為繪制機構運動(dòng)簡(jiǎn)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、 分析升降平臺運動(dòng)的確定性。計算升降平臺的自由度數，并將結果與實(shí)際升降平臺的原動(dòng)件數相對照，若與實(shí)際情況不符，要找出原因及時(shí)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、選擇適當的比例尺，根據該機械的運動(dòng)尺寸，確定各運動(dòng)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
