【摘要】 为了解决多自由度汽车电动座椅出厂位姿调整过程中的耦合问题,消除座垫不规则表面对调整过程的影响,实现座椅位姿的快速调整,提出了一种基于控制变量法的座椅位姿调整方法。首先,根据座垫表面的拟合曲线和座椅的几何结构,建立参考坐标系并分析座椅外部轮廓上的点与当前运动关节的转角或位移之间的数学关系。然后计算出座椅的当前位姿并给出调整方案。最后,通过仿真和实验验证了所提方法的可行性。仿真和实验结果表明:该方法能够消除座垫不规则表面和关节耦合对调整过程的影响,同时能提高调整的准确度和效率。研究结果对改进汽车电动座椅出厂位姿调整方法和提高座椅调整效率有一定的参考意义。更多还原

【Abstract】 To solve the coupling problems in the factory position and orientation adjustment process of multi freedom degree automobile electric seat and eliminate the influence of cushion irregular surface on the adjustment process to achieve the rapidly adjustment,a seat position and orientation adjustment method based on the control variable method was proposed.Firstly,according to the fitting curve of the cushion surface and the seat geometry structure,the mathematical relationship between the point on the seat external contour and the joint angles or displacement was established.Then,the current position and orientation of seat was calculated and the seat adjustment scheme was put forward.Lastly,the simulation and experimental verification was carried out to verify the feasibility of the proposed method.Simulation and experimental results showed that the proposed method could eliminate the effect of cushion irregular surface and joint coupling on the adjustment process and improve the accuracy and efficiency of adjustment.The results of the study have certain reference significance for improving the factory position and orientation adjustment method of automobile electric seat and seat adjustment efficiency.更多还原
