為月b :體呈現本創作之功效,茲將本創作及先前技術 不之前叉肩架在相同條件下進行結構強度(剛性)分析 以及應力分析。而以下所述之數據係為習用與本案之比對 參考值,並非限制本案申請專利範圍或實施之條件。 首先,在輕量化表現方面,先前背景中所述之前叉肩 架(如第一圖,以下簡稱習知肩架),其重量約1328,而本 案第四圖所示之前叉肩架(以下簡稱本案肩架),其重量為 92g。本案之輕量化表現較習知肩架優。 就結構強度(剛性)方面,在相同條件下進行剛性分 析’變形量愈大,表示結構強度(剛性)愈弱。習知肩架之 變形量為0·014 3ππη,而本案肩架之變形量為00095min。本In order to demonstrate the effect of this creation, we will perform structural strength (rigidity) analysis and stress analysis of this creation and the previous technology. The data described below are the reference values for comparison between customary and this case, and are not conditions that limit the scope or implementation of the patent application in this case. First of all, in terms of lightweight performance, the front fork shoulder frame (such as the first picture, hereinafter referred to as the conventional shoulder frame) described in the previous background has a weight of about 1328, while the front fork shoulder frame (hereinafter referred to as the fourth image in the present case) Shoulder case in this case), its weight is 92g. The lightweight performance of this case is better than the conventional shoulder stand. In terms of structural strength (rigidity), the larger the amount of deformation under the same conditions, the weaker the structural strength (rigidity). The deformation amount of the conventional shoulder frame is 0.014 3ππη, while the deformation amount of the shoulder frame in this case is 00095min. this
案肩架變形量小於習知肩架,所以結構強度(剛性)表現較 習知肩架優。 就結構應力方面,若以應用最廣泛、最成熟的有限單 元分析(Finite Element Analysis)為主要架構,探討 單一元件在承受外力後的反應狀況,如内部的應力大小、 變形量等。應力值愈大表示應力集中現象愈明顯,力之傳The deformation of the shoulder rack is smaller than that of the conventional shoulder rack, so the structural strength (rigidity) performance is better than that of the conventional shoulder rack. In terms of structural stress, if the most widely used and mature Finite Element Analysis is the main framework, the response of a single element to external forces, such as the internal stress and deformation, is discussed. The larger the stress value is, the more obvious the stress concentration phenomenon is.
