【摘要】：汽车座椅调角器是汽车中座椅部分的关键零部件，为了适应人体的姿势，可以通过调节座椅与人体靠背的角度，从而最大限度的满足人们对舒适性的要求和提供座椅对人体的支撑力。在调角器的实际应用中需满足以下几个方面：（1）零件在使用过程中要保证有足够的强度，在突发状况下，例如发生交通事故时，将会承受突如其来的外力冲击，为了保证人员的安全，零件必须具有足够的强度；（2）当乘客或者是驾驶人员进行座椅调节时，要能够确保使用人员能够方便快捷的进行调节；（3）调角器零部件在与汽车座椅进行装配时，要符合一定的间隙设计要求。本课题主要研究内容如下：一、对调角器的各种成型工艺进行对比分析，得出适合行星齿轮式调角器的成型工艺。二、分别对普通冲裁工艺、精密冲裁工艺进行对比，并对冲孔半冲孔工艺进行了解。三、利用DEFORM-3D有限元数值模拟软件对精密冲裁工艺，半冲孔工艺进行数值模拟实验验证和优化，并进一步对行星齿轮式调角器进行冲裁模拟。四、分析说明通过数值模拟而得出的数据和结果。本文对精密冲裁和普通冲裁两种成型工艺进行比较。由于调角器是汽车座椅上的关键件、安全件，其功能和质量是关乎座椅的档次和可乘人员的安全，所以调角器对质量和工艺要求较高。对调角器成型过程进行数值模拟，通过对成型过程中应力应变的分布、几何形状、成型尺寸进行分析说明，说明工艺的特点难点，并针对工艺目标的实现，说明模具达到工艺要求的具体办法和关键模具的结构原理。由于行星齿轮式汽车座椅调角器是德国设计，有德国知识产权，，产品在德国轿车上广泛应用，本研究有应用价值，是较先进的国际水平，有较好的利用价值。
[Abstract]:The car seat angle adjuster is the key part of the seat part of the automobile. In order to adapt to the posture of the human body, the angle between the seat and the body back can be adjusted by adjusting the angle of the seat and the back of the human body. So as to meet the maximum comfort requirements and provide seat support to the human body. In the practical application of the angle regulator, the following aspects should be satisfied: (1) the parts should be guaranteed to have sufficient strength in the process of use, and in sudden situations, such as traffic accidents, they will be subjected to sudden external force shocks. In order to ensure the safety of personnel, the parts must be of sufficient strength; (2) when the passenger or driver adjusts the seat, it should be able to ensure that the user can easily and quickly adjust; (3) the parts of angle adjuster should meet the requirement of clearance design when assembling with automobile seat. The main contents of this paper are as follows: 1. By comparing and analyzing the various forming processes of the angle adjuster, the forming process suitable for the planetary gear angle adjuster is obtained. Secondly, the common blanking process and the precision blanking process are compared, and the punching semi-punching process is understood. Thirdly, DEFORM-3D finite element numerical simulation software is used to verify and optimize the precision blanking process and semi-punching process, and the planetary gear angle adjuster is further simulated. Fourthly, the data and results obtained by numerical simulation are analyzed and explained. This paper compares the precision blanking process with the common blanking process. Because the angle adjuster is the key part in the automobile seat and the safety part, its function and quality are related to the safety of the seats and the safety of the passengers, so the angle adjuster requires high quality and technology. Through the numerical simulation of the forming process of the angle adjuster, the distribution of stress and strain, the geometric shape and the size of the forming process are analyzed and explained, and the characteristics and difficulties of the process are explained, and the realization of the process goal is pointed out. The concrete method and the structure principle of the key die are explained. Because the planetary gear car seat angle adjuster is a German design with German intellectual property rights and its products are widely used in German cars, this research has applied value, is a more advanced international level, and has better utilization value.
