In the process of electric vehicle operation,the heat generated by the battery charge and discharge will cause the temperature of the battery to rise,and the temperature will affect the performance,service life and even combustion explosion of the battery.In the development of power battery pack,it is necessary to simulate and analyze the temperature field in the battery pack,and combinethe test of the battery-bed to ensure that the thermal performance meets the requirements in the operation process.In this paper,thethermal simulation analysis model of the battery pack based on the coupling of equivalent circuit and the heat flow was established,andits simulation results wereagreement with test results.It is shown that the simulation method is correct,which can provide advices andsuggestions for the design and development of EV power battery pack.

车身内表跟踪喷涂机器人及其输送链组成的系统,在安装和施工过程中,不可避免地存在安装误差,为实现离线编程和不同机器人的程序互拷,需要对机器人基座进行标定。本文描述了轨道机器人的跟踪运动学模型,建立跟踪坐标系误差模型。将某台机器人定义为主机器人,通过跟踪示教车身特征点,辨识其他机器人跟踪坐标系参数,使从机器人精度接近主机器人,实现不同机器人的程序互拷。
车身内表喷涂站的开门机在打开车门过程中,开门机与车门的运动轨迹不同步而引发一些故障报警。根据车体铰链的两个中心坐标,获得铰链轴线方程,构建铰链坐标系。通过齐次变换,将平面圆轨迹转换到开门机空间坐标系下,得到开门机的精确运动轨迹。获得的开门机轨迹分布在以铰链为轴线的空间圆弧上,开门机轨迹与车门运动同步,消除了两者的运动偏差。
辊床是涂装车间普遍使用的一种车身输送形式,广泛应用于涂装车间各工艺线的地面输送。本文通过校核辊床的侧板强度、螺栓强度、轴承寿命及电动机选型,分析由新车型并入带来的载荷增加的影响,对其他涂装车间也有很大的参考价值。
汽车制造行业在国内发展日渐成熟,国产输送设备也趋于稳定,涂装车间的设备制造及安装也已积累越来越多的经验。本文以某公司新建涂装车间为例,对输送设备的创新改进进行总结与分享。
