具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的目的是提供一种结构稳定、尺寸灵活的道路模拟试验台架，用以适应不同类型底盘的道路模拟试验需要。
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。
如图1-5所示，本实施例提供一种道路模拟试验台架，包括立柱支撑结构10、水平调节结构和连接盘6。其中，立柱支撑结构10用以支撑水平调节结构，水平调节结构能够改变横向尺寸，从而适应不同底盘的模拟试验需要，连接盘6用以和激励结构接触，将激励传递至水平调节结构，从而模拟不同路面条件下底盘的震动情况。
水平调节结构包括调节支架4、直线导向结构和承载板5，直线导向结构固定于调节支架4上，直线导向结构用以支撑承载板5并使承载板5沿直线运动，调节支架4的第一端连接于立柱支撑结构10上。直线导向结构有多种类型，本领域技术人员可以根据实际需要进行选择。连接盘6铰接于直线导向结构的下侧，可将不同方向上的震动进行传递。
使用时，将立柱支撑结构10固定于地面或底座上，将试验车辆的底盘固定于承载板5上，然后启动激励结构，使激励结构向连接盘6传递激励即可。可根据底盘的实际尺寸调整承载板5所在位置，使试验台可测量车辆最大轮距得到大幅度提升，满足大底盘的测试需求。立柱10-2的固定方式有多种，本实施例的立柱10-2下端具有法兰端面，法兰端面用以通过螺栓固定于地面上。
为了提高整体稳定性，本实施例的立柱支撑结构10包括连接架10-1、垂向板和两个立柱10-2，两个立柱10-2的上端通过连接架10-1固定连接，垂向板固定于连接架10-1的端部，调节支架4的第一端连接于垂向板上，承载板5位于两个立柱10-2的轴线所在平面上。双立柱结构用以承受由 于力臂延长所带来的力和力矩，在增加试验台架承重的同时，有效地避免试验台激振头承受过大弯矩而损坏，从而能更加全面地满足工程机械相关车辆，特别是大底盘、大吨位的车辆对道路模拟试验的要求。
为了便于调整底盘的高度，本实施例的调节支架4通过竖直调节结构连接于垂向板上，竖直调节结构包括竖直导轨8和滑块7，竖直导轨8沿竖直方向通过固定座9固定于垂向板上，滑块7滑动设置于竖直导轨8上，调节支架4的第一端与滑块7固定连接。通过改变滑块7在竖直导轨8上的位置，可调整底盘的高度。
为了避免底盘与立柱支撑结构10发生碰撞，本实施例的调节支架4为Z形结构，包括第一水平部、竖直部和第二水平部，第二水平部的第一端与滑块7固定连接，第二水平部的第二端与竖直部的下端固定相连，竖直部的上端与第一水平部的第一端固定相连，连接盘6铰接于第一水平部的下侧。调节支架4为桁架结构，由若干方钢焊接而成。连接盘6通过铰链11与第一水平部铰接，其中连接盘6与铰链11的一个自由端通过螺栓固定连接，铰链11的另一个自由端与第一水平部通过螺栓固定连接，铰链11的两个自由端能够相对转动。通过使滑块7在竖直导轨8上向上滑动，可使承载板5高于连接架10-1，从而避免底盘和连接架10-1相互碰撞。
当水平调节结构为两个时，可实现双向尺寸调节，当水平调节结构为一个时，可实现单向尺寸调节。本实施例中，垂向板和水平调节结构均为两个，且对称分布于立柱支撑结构10的两侧，水平调节结构包括第一水平调节结构和第二水平调节结构。通过使第一水平调节结构和第二水平调节结构对称设置，可平衡两侧力矩，从而提高整体稳定性。
本实施例中，第一水平调节结构的直线导向结构为丝杠螺母组件，第二水平调节结构的直线导向结构为直线轴承组件。丝杠螺母组件包括丝杠13和螺母14，丝杠13的两端通过轴承座12连接于第一水平调节结构的调节支架4上，第一水平调节结构的承载板5与螺母14固定相连。通过驱动电机驱动丝杠13转动，可调整螺母14在丝杠13上的轴向位置。直线轴承组件包括光轴1和直线轴承2，光轴1的两端通过光轴座3连接于第二水平调节结构的调节支架4上，第二水平调节结构的承载板5与直 线轴承2固定相连。
由于丝杠13和光轴1的径向承载能力有限，为了满足大吨位底盘的测试需求，本实施例的承载板5与调节支架4滑动接触，使丝杠13仅承受轴向力，光轴1仅用于导向。
在调整承载板5的位置时，为了避免承载板5脱离调节支架4，本实施例的调节支架4上远离立柱支撑结构10的一端具有限位挡板，限位挡板用以限制承载板5的位移。
根据力平衡和力矩平衡原理，可得到调节支架4的力和力矩方程，可计算得到调节支架4的力和力矩图如图5所示。可以看出，合理选择连接盘6与道路模拟试验台的连接位置可避免由于力臂增加而附加的弯矩，因此保证了试验台的寿命。
本说明书中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处。综上所述，本说明书内容不应理解为对本发明的限制。
