Description

适用对象:中小学生科技创新项目、青少年科技实践操作等。

动力参数(可用于实验报告^_^):太阳能发电板全工况输出电压约2V,使用两块太阳能发电板串联后输出电压约为4V;马达启动电压约1.7V,全工况电压约4V。此处全工况状态指小车在充足光照条件下全速前进时各动力部分达到的数值。

光照要求:这台车不使用电池辅助,所以对光照要求比较高。要求晴天,必须可见完整太阳,可见大部分蓝天为最佳、正午阳光为宜。正确安装的小车,若初次行驶失败,多半为光照条件不满足,可选择光照良好的时间多做几次测试。注意季节不同,太阳角度的不同,可通过调节太阳能板倾角来补充光的损失,具体各位可以参考安装教程里说明。

知识点:

1- 了解不同形式能量的转换过程。利用太阳能板收集阳光,转换成电力,供应给小马达,小马达将电能转换成动能,驱动小车前进。

2- 动力传输结构的初步认识,通过马达的转轴输出动力,通过皮带传递给车轴上的皮带轮做功。大小皮带轮之间有一个减速的关系,这和皮带轮的直径成正比。

3- 电路的并联和串联练习。小车制作中涉及到基础的电路串并联知识。两块太阳能板之间是串联的。

4- 接触小的物理设备,诸如电机、太阳能板等,拉进抽象概念和实物之间的距离。培养动手能力,制作一个平时不多见的科学玩具,可以开阔眼界。undefined
