鐓同 的英文怎麼說
中文拼音 [dūntóng]-
The process parameters of electric upsetting include : velocities of upsetting cylinder and anvil cylinder, heating current, preheating length and time, etc. because different materials have different mechanical, electric and thermal characteristics, and there are effects between different parameters, the determination of those parameters becomes a complex problem
電熱鐓粗成形過程的工藝參數主要包括鐓粗缸活塞運動速度、砧子缸活塞運動速度、鐓粗壓力、加熱電流和預熱長度等。這些參數的選擇是一個復雜的問題，其復雜性不僅在於不同的材料具有不同的力學、電和熱傳導特性，而且各參數相互影響、相互制約。After description of slide line fields according to the different proportion of width / diameter, the stress function in flat plate upsetting has been determined, the changing rule of slide line fields been described, the process of column upsetting been simulated by using the software of abaqus and the theoretical value been proved through comparing the simulation value with the theoretical value
摘要本文應用滑移線理論來求解平板鐓粗模型，描述了在不同寬徑比下的滑移線場，確立該模型單元的應力場表達式，描述其滑移線場的變化規律，最後運用abaqus軟體對圓柱體鐓粗進行數值模擬，將模擬值與理論值進行對比，對理論值進行驗證。Also supply cold heading, forging, die casting, powdered metal, extrusions, weldments, tig welding, and screw machine parts including all necessary dies and tooling
