一种测试转向管柱向上转动角度变化量的装置及方法
摘要：
本发明涉及一种测试转向管柱向上转动角度变化量的装置，包括设在转向管柱实验安装台和转向管柱之间的装置本体,所述装置本体包括连接在所述转向管柱实验安装台上的角度变化量检测构件、一端与角度变化量检测构件配合连接的曲柄连杆机构、一端与曲柄连杆机构另一端连接的转向管柱连接件，所述转向管柱连接件的另一端和曲柄连杆机构的另一端还分别并与所述转向管柱配合连接。本发明能够在人体模块实验过程中，测量转向管柱向上角度变化量，并解决角速度传感器零飘大，对较小的角度变化量不灵敏、积分计算存在较大误差的问题。本发明还涉及一种测试转向管柱向上转动角度变化量的方法，为汽车碰撞安全研发设计提供支撑。
摘要（英）：

The invention relates to a device for testing the upward rotation angle variable quantity of a steering column. The device comprises a device body arranged between a steering column experiment mount table and the steering column, the device body comprises an angle variable quantity detection member connected to the steering column experiment mount table, a crank link mechanism connected with the angle variable quantity detection member on one end in a matching manner, and a steering column connecting member connected with the other end of the crank link mechanism on one end, and the other end of the steering column connecting member and the other end of the crank link mechanism are connected with the steering column in a matching manner. The device can measure the upward rotation angle variable quantity of the steering column during the human body module experiment process, and solves the problem that the angular velocity sensor is large in null shift, and is insensitive to relatively-small angle variable quantity, and the integral computation has a relatively-large error. The invention also relates to a method for testing the upward rotation angle variable quantity of a steering column, and the method provides support for automotive crash safety research, development and design.
