DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport simulation device, and more particularly to a transport simulation device suitable for use in simulating and evaluating damage to continuous vibration and impact during normal transport.

[0002]

2. Description of the Related Art For example, when a product is housed in a container such as a container and transported, the cargo may collapse or be damaged by vibrations or impacts continuously acting during transportation by truck or wagon. Therefore, by loading containers such as containers containing products on the loading platform of traveling vehicles such as trucks in advance and actually traveling assuming the actual transport situation, by applying vibration and impact during transportation to the containers etc. In some cases, the collapse and damage of the cargo are reproduced and evaluated.

[0003] According to this test method, it is possible to grasp to some extent the state of collapse or damage that may occur during actual transportation, and it is possible to take measures. However, this test takes an enormous amount of time, and it is difficult to test every conceivable transportation situation.

[0004] As a countermeasure against the problem, it is generated and evaluated by simulation using a transport simulation device.

[0005] As this transport simulation device,
A method is widely used in which a vibration tester applies vibration to a container such as a container fixed on a vibration table by repeatedly applying fine amplitude vibration to a vibration table using a hydraulic servo device or the like, Many large vibration testing machines vibrate the vibration table only in one-dimensional direction.

As another transport simulation device, an impact test device is used. A simulation method using the impact test device is such that a container such as a container for storing products is slid down on an inclined table which is inclined to a container or the like. There is a method of evaluating the damage state by giving an impact or by lifting the container to a predetermined height by a crane or the like and dropping the container to give an impact to a container or the like.

[0007] As a prior art relating to an impact durability inspection apparatus for measuring the durability against vibration and impact applied to a product during transportation or the like, there is Japanese Utility Model Application Laid-Open No. 6-51851. The impact durability inspection apparatus disclosed in this prior art lowers an inspection table on which a product, that is, a sample to be inspected, is placed at a predetermined speed by lowering means, and collides with a receiving table arranged below the inspection table. The impact durability test of the product is performed by repeating an impact process of stopping and giving an impact to the inspection table and the sample to be inspected, and raising and returning the lowered inspection table by the ascending means a set number of times.

[0008]

In the simulation method for applying vibration to a container such as a container containing a product by the above-mentioned vibration tester, it is possible to evaluate to some extent the collapse or damage of a load caused by repeated vibration. It is difficult to evaluate the state of collapse or damage caused by impact. On the other hand, the method using an impact device evaluates each time a shock is applied. In the prior art disclosed in Japanese Utility Model Laid-Open Publication No. 6-51851, the durability of the product itself is evaluated by continuously applying an impact to the product itself. Therefore, any of these methods faithfully reproduces the collapse or damage caused by vibrations and shocks acting repeatedly three-dimensionally during the actual transportation in which products are stored in containers such as pallets and transported. Is impossible.

Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to easily collapse or damage a load caused by vibration or impact during transportation in accordance with actual product transportation.

And the second vibration and shock applying means repeatedly applies vibrations and shocks in two directions intersecting the table on the same horizontal plane, thereby applying three-dimensional vibrations and shocks to the table and the container according to the actual transport conditions. This makes it possible to easily reproduce and evaluate the collapse and damage of the cargo.

Another transportation simulation apparatus according to the present invention for achieving the above object is a base, a support supported on the base so as to be able to move up and down, and a straight line on a horizontal plane on the support. A swinging member supported so as to be reciprocally movable in a direction, and a container for holding a product supported on the swinging member so as to be reciprocally movable in a direction intersecting a reciprocating direction of the swinging member on a horizontal plane. A table to be placed, a vertical vibration impact applying means provided between the base and the support table to reciprocate the support table in the vertical direction to apply vibration and impact to the support table, and to swing with the support table. A first vibration / shock applying means provided between the swing member and the table, for causing the swing member to reciprocate linearly in a horizontal plane to apply vibration and impact to the swing member; The table is set in the horizontal plane. And having a second vibration impact application means for applying vibration and shock to the table reciprocated in a direction crossing moving direction in a plan view.

Accordingly, the support table is moved up and down by the vertical vibration impact applying means to apply vertical vibration and impact to the table and the container accommodating the products on the table via the swinging member, and to perform the first vibration. The swinging member is reciprocated in a horizontal direction in a horizontal plane by an impact applying means to apply a vibration and an impact in a linear direction in the horizontal plane to the table and a container accommodating products on the table, and to apply a second vibration and impact.
