The invention discloses a pickup truck rear bumper boundary construction method and a structure design and verification method.The method comprises the step of determining the boundary position of the appearance of a rear bumper and the main section structure, and the step of determining the boundary position of the appearance of the rear bumper comprises the following steps that the assembling position of the rear bumper is input according to the whole truck plan; a departure angle is determined, the length of the rear suspension is determined, and the outline of the outermost end of the rear bumper is obtained; the distance between the intersection point of the protruding point and the tangent line of the rear bumper and the ground is obtained; determining an X-direction gap between the rear bumper and the container; determining the terrain clearance of the pedal device; determining a gap between the rear bumper and the skirt; determining a gap between a tail door and a pedal device after opening; according to the method for constructing the boundary of the rear bumper, the modeling range of the rear bumper is limited, the accuracy of determining the boundary position of the rear bumper is improved, the time for repeatedly adjusting data is saved, the modeling range is input at the initial stage of a CAS face at the same time, the accuracy of determining the boundary position of the rear bumper is improved, and the modeling creation efficiency is improved.

    本发明公开了皮卡后保险杠边界构造方法、结构设计及验证方法,包括确定后保险杠外形边界位置和主断面结构,确定后保险杠外形边界位置包括以下步骤:根据整车规划输入后保险杠装配位置;确定离去角,确定后悬长度,得到后保险杠最外端的外廓线;得到后保险杠的突出点与切线的交点距地面尺寸;确定后保险杠与货箱之间的X向间隙;确定踏板装置离地高度;确定后保险杠距裙边间隙;确定尾门开启后距踏板装置间隙;通过本发明的后保险杠边界构造方法,限制后保险杠造型范围,提高确定后保险杠边界位置的准确性,节省反复调整数据的时间,实现同时CAS面初期输入造型范围、提高后保险杠边界位置确定的准确性,提高造型创作的效率。
