Based on an analysis of the structures of large parts in machine tools as well as their loading conditions, this paper proposes a method of applying finite element analysis to the calcultion of structures composed of plates and beams with an aim to raise the accuracy of calculation. In order to reduce the requirement on the computer memory, certain measures have been taken to adapt the mechanical models and method of computation to the situation.

Three methods of theoretical dynamic analysis for a steel tower are conducted.(1) Space-truss-multimass dynamic system calculated with the method of mode analysis; (2) Space truss dynamic system calculated with the same method; (3) Space-truss-multimass dynamic system, the response of which is calculated with inputting the earthquake record.For verifying the results of the analysis, two other methods of dynamic test on the prototype structure are also made. (1) forced vibration carried out by vibrators; (2) microseismic measurement recorded by graph and by magnetic tape and analysed by signal-processor. The results of different methods of analysis and tests are compared in the paper.

In the revision of the 《Specifications for the Design of Rigid Pavement》, the finite difference method was used, as presented in this paper, to calculate the stresses and deformations of the rigid pavement under wheel loads so as to verify the result obtained by the finite element method originally used. It is found that it has the same degree of accuracy as compared with the finite element method. Besides, the mathematical-mechanical models used and its method of calculation are also simpler than the former...

In the revision of the 《Specifications for the Design of Rigid Pavement》, the finite difference method was used, as presented in this paper, to calculate the stresses and deformations of the rigid pavement under wheel loads so as to verify the result obtained by the finite element method originally used. It is found that it has the same degree of accuracy as compared with the finite element method. Besides, the mathematical-mechanical models used and its method of calculation are also simpler than the former method. Consequently it is also deemed as a feasible method to be used in the design of rigid pavvement.

在修改《刚性路面》设计规范中,为了验算有限单元法解,本文利用有限差分法算出水泥混凝土路面在车轮荷载作用下的应力和变形.与有限单元法比较,有限差分法解具有同样的精度;所用数学力学模型及计算方法较为简单,易于掌握.有限差分法也是计算水泥混凝土路面的可行方法.
