按键与旋钮是汽车中控台上数量较多且操作较频繁的人机接口,整车厂需要对出厂产品的按键和旋钮手感特性进行定量测试,以衡量其与设计参数之间的差异,达到控制产品质量的目的[1]。目前市场上常见的测试方法,大多采用单轴电机与力和扭矩传感器来进行测量,无法根据力和扭矩的信号输入进行不同方向的抓手位置调整,也无法消除侧向力不平衡导致的测量数据偏移。本文介绍了一种采用6轴机械手和6轴力和扭矩传感器进行按键和旋钮手感测试的方法,该方法能根据力和扭矩的输入信号,动态的调整抓手位置方向和位移,消除侧向力不平衡导致的测量数据失真,准确地测量出按键和旋钮的参数特征,并且描述了该方法实现步骤。
Buttons and knobs are man-machine interfaces that have a large number on the center console of the car and operate more frequently. The OEM needs to quantitatively test the characteristics of buttons and knobs of the manufactured products to measure the difference from the design parameters The purpose of controlling product quality [1]. Common test methods currently on the market are mostly single-axis motors with force and torque sensors to measure, can not be based on force and torque signal input for different directions of the grip position adjustment, can not eliminate the lateral force imbalance caused by the measurement Data offset. This article presents a method for testing key and knob feel using a 6-axis robot and a 6-axis force and torque sensor that dynamically adjusts the direction and displacement of the gripper based on input signals for force and torque to eliminate lateral forces The measured data caused by unbalanced distortion accurately measure the parameters of the keys and knobs, and describe the method to achieve the steps.
