【摘要】：破碎機是許多行業(yè)破碎工藝中非常關鍵的機械設備。為了突破傳統(tǒng)的齒輥破碎機的設計方法,本文建立了齒輥破碎機虛擬樣機系統(tǒng),運用虛擬樣機技術對破碎機進行仿真分析和參數(shù)化設計。以強力齒輥破碎機為研究對象,對其進行自頂向下的整機建模,通過了裝配干涉檢測。采用Pro/E三維軟件和VC++6.0開發(fā)平臺,實現(xiàn)了破碎機齒板的參數(shù)化變型設計,為產(chǎn)品快速設計奠定了良好的基礎;在ANSYS Workbench軟件中對采用Pro/E建立的齒輥破碎機齒板的三維模型進行了靜力學分析,根據(jù)分析結果提出了對輥齒較薄弱地方加強的三種方案,通過分析對比,最終確定了較為理想的方案。對破碎機進行ADAMS運動學和動力學仿真。首先,通過分析破碎機運動特性,明確了破碎機的工作過程,通過了運動干涉檢測。其次,通過分析有滾動現(xiàn)象的物料的接觸力,明確了物料的整個破碎過程的情況,分析得出其破碎力比無滾動現(xiàn)象的要大。通過對比三種不同材料的物料接觸力的大小。仿真結果的接觸力與理論計算的擠壓力非常接近,這從理論上驗證了虛擬樣機系統(tǒng)的仿真結果是可靠有效的,也反映了對齒板受力的理論分析方法是可行的�；谙嗨评碚搶μ摂M樣機系統(tǒng)進行可靠性評估。運用相似分析方法構造相似元,計算相似元值,求出系統(tǒng)相似度。本文得到虛擬樣機的相似度為0.844,證明了虛擬樣機仿真結果是可信的。
[Abstract]:Crusher is a very important mechanical equipment in many industries. In order to break through the traditional design method of tooth roller crusher, a virtual prototype system of tooth roller crusher is established in this paper. The virtual prototype technology is used to simulate and analyze the crusher and to design its parameters. The top-down whole machine model was built on the strong tooth roller crusher as the research object, and the assembly interference detection was carried out. The parametric variant design of the tooth plate of the crusher is realized by using the Pro/E 3D software and the development platform of VC 6.0, which lays a good foundation for the rapid design of the product. In ANSYS Workbench software, the three dimensional model of tooth plate of tooth roller crusher established by Pro/E is analyzed statically. According to the analysis results, three schemes for strengthening the weak part of the roller tooth are put forward, and through the analysis and comparison, three kinds of schemes are put forward to strengthen the tooth plate of the tooth roll crusher. Finally, a more ideal scheme is determined. The ADAMS kinematics and dynamics simulation of the crusher is carried out. Firstly, the working process of the crusher is clarified by analyzing the motion characteristics of the crusher, and the motion interference detection is adopted. Secondly, by analyzing the contact force of the material with rolling phenomenon, the situation of the whole crushing process of the material is clarified, and the crushing force of the material is greater than that of the one without rolling phenomenon. The contact force of three different materials was compared. The contact force of the simulation results is very close to that of the theoretical calculation, which verifies theoretically that the simulation results of the virtual prototype system are reliable and effective, and also reflects the feasibility of the theoretical analysis method for the force on the tooth plate. The reliability of virtual prototype system is evaluated based on similarity theory. The similarity analysis method is used to construct the similarity element, to calculate the similarity element value, and to calculate the similarity degree of the system. In this paper, the similarity of virtual prototype is 0.844, which proves that the simulation result of virtual prototype is credible.
