【摘要】：以錫青銅連桿襯套為研究對象,通過Deform-3D軟件進行了數(shù)值模擬。利用單一因素工藝參數(shù)試驗法和正交試驗優(yōu)化試驗方法對發(fā)動機連桿襯套的溫擠壓過程進行了數(shù)值模擬分析,得到了摩擦因數(shù)、溫擠壓速度、溫擠壓溫度等參數(shù)在溫擠壓過程中對擠壓力、損傷值的影響規(guī)律和顯著性影響。利用極差分析得到了兩組最優(yōu)的溫擠壓工藝參數(shù),并通過數(shù)值模擬兩組較優(yōu)解對擠壓力、損傷值的影響規(guī)律的對比,最終得到一組最優(yōu)解,即摩擦因數(shù)為0.1、溫擠壓速度為5 mm·s-1、溫擠壓溫度為700℃。根據(jù)連桿襯套溫擠壓試驗驗證了使用優(yōu)化后的工藝參數(shù)能夠制造出表面質量高的成形件。
[Abstract]:The tin bronze connecting rod bushing was numerically simulated by Deform-3D software. The temperature extrusion process of engine connecting rod bushing was simulated and analyzed by single factor process parameter test method and orthogonal test optimization test method. The friction coefficient and temperature extrusion speed were obtained. The influence of temperature and other parameters on the extrusion force and damage value in the process of warm extrusion is significant. By means of range analysis, two groups of optimal warm extrusion process parameters are obtained. By comparing the effects of two groups of optimal solutions on extrusion pressure and damage value, a group of optimal solutions, that is, friction coefficient of 0.1, is obtained. The temperature extrusion temperature is 700 鈩，
